+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by

+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.

+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program

+app_conference is a channel-independent conference application.
+
+Design goals
+It has several design goals which are different than meetme:
+
+    * It does not require a zap channel for timing.
+    * It is very efficient when used with channels which support DTX (silence
+	detection/discontinuous transmission).
+
+    * It can do VAD on channels which do not support DTX (although this 
+	is more expensive than just mixing them, but less expensive then
+	encoding; therefore it might still be a win). 
+    * It presents messages on the Monitor interface for determine which 
+	speakers are active. 
+
+
+I believe that people other than myself are using this, but my environment is
+pretty rigid, and cases outside of this aren't tested:
+
+    * Some callers come from the PSTN via IAX2 from a box with Zaptel cards, 
+	via uLaw.
+    * Other callers come from iaxclient based softphones using speex
+     	(was GSM) via IAX2 (with DTX). 
+    * Some conferences have a single SIP channel which listens in GSM.
+
+
+Mixing design
+
+    * Minimize encoding/decoding, minimize mixing.
+    * Minimize generational loss from trancoding.
+    * Usual cases are handled very efficiently:
+          o One speaker: That speaker's frame is sent directly to each 
+		participant which uses the same codec. It is trancoded 
+		_once_ for each additional codec type used by participants.
+          o Two speakers: Each speaker gets the other speaker's frames.  
+		The two speaker's frames are decoded and mixed, and then 
+		encoded _once_ for each codec type used by participants. 
+
+
+License
+Naturally, app_conference is GPL. The CVS also includes parts of libspeex,
+which is distributed under it's a BSD-style license.
+
+Getting app_conference
+app_conference is available from the 'iaxclient' project on sourceforge:
+
+    * CVS browse: http://iaxclient.cvs.sourceforge.net/iaxclient/app_conference/
+    * Project page: http://sourceforge.net/projects/iaxclient/
+
+
+Compiling app_conference
+
+    * just like any other asterisk application.
+    * Some makefile fiddling may be necessary 
+
+
+Using app_conference
+There is no configuration file. Conferences are created on-the-fly.
+
+Dialplan syntax: Conference(ConferenceName|Flags|Priority[|VADSTART|VADCONTINUE])
+
+    * ConferenceName: Whatever you want to name the conference
+    * Flags one of more of the following:
+          o M: Moderator (presently same as speaker)
+          o S: Speaker
+          o L: Listener
+          o T: "Telephone caller" (just for stats?).
+          o V: Do VAD on this caller
+          o D: Use Denoise filter on this caller. 
+          o d: Send manager events when DTMF is received.
+          o q: Do not play enter or exit sounds.
+          o i: use inband dtmf broadcast.
+          o t: use rfc dtmf signal broadcast.
+    * Priority: Currently ignored; was to be a "speaking priority" so a 
+	higher priority caller could "override" others.
+    * VADSTART: Optional: "probability" to use to detect start of speech.
+    * VADCONTINUE: Optional: "probability" to use to detect continuation 
+	of speech. 
+
+
+Features / CLI/Manager Commands
+
+    * conference debug <conference_name> [ on | off ]  
+	enable debugging for a conference
+
+    * conference show stats  show conference stats
+
+    * conference play sound <channel-id> <sound-file> [mute]
+	play a sound to a conference member, optionally muting them.
+
+Manager Events
+app_conference generates several detailed manager events so that applications
+interfacing with the manager API can monitor conferences:
+
+    * ConferenceState:  sent as members begin/end speaking.
+	Channel: The channel
+	State: "speaking" or "silent"
+
+    * ConferenceDTMF: sent when conference members send DTMF to the conference
+	Channel: The channel
+	Key: The DTMF key send [0-9*#]
+
+    * ConferenceSoundComplete: send when the conference has finished playing 
+		a sound to a user	
+	Channel: The channel
+	Sound: The first 255 bytes of the file requested in conference play 
+		sound CLI/Mgr command.	
+
+
+Benchmarking
+It would be nice to have solid benchmarks to present, but a good size 
+machine should be able to handle many callers when either (a) they are 
+using DTX, or (b) they are listen-only.  It's used often with hundreds of
+simultaneous callers.
+
+Discussion
+The iaxclient-devel mailing list is probably as good a place as any to discuss.

+Matt Florell Changes for VD_app_conference tarball version. In order to use this
+as seemlessly as possible for VICIDIAL it was necessary to modify the code. This
+module can now be used in place of using meetme for VICIDIAL. This is 
+experimental, please test thoroughly before putting it in production.
+
+CHANGES MADE FOR VICIDIAL:
+
+- Default to member type of S instead of L
+- Commented out many repetative NOTICEs and ERRORs 
+- Added entry and exit sounds except for Local/786 and Local/8500998 (VDsilent and DTMFapp)
+- Added conf-onlyperson mesage to first conference participant
+- Included enter.gsm and leave.gsm files as well as DTMF wav and gsm sounds
+- Removed restart from "make install" and added audio file copying
+- If no 'd' option is set and DTMF frames are detected, the DTMF audio will be played to the member
+- Added 'q' flag to prevent playing of entry/exit sounds
+- Added 'i' flag to enable playing of DTMF sounds inband to all members
+- Added 't' flag to enable sending of RFC DTMF signals to all members
+- Changed delimiter to pipe | from slash / to be more compliant with meetme standards

+NOTE TO 64-BIT LINUX USERS:
+If you have problems with 64-bit Linux please use the included 64_Makefile instead of the default one.

+VICIDIAL and app_conference
+(1.2 tree) EXPERIMENTAL!!! 
+
+app_conference offers the plusses of being able to do conferencing
+without any zaptel hardware or timers as well as doing native codec
+streaming, meaning no manditory downsampling to slin like meetme.
+These two features alone mean a rather significant performance boost
+to companies who only use VOIP for agents and trunks as well as not
+requiring the cost of zaptel hardware or the nightmare of getting
+ztdummy to work on some systems.
+
+As of right now, I have a test system fully up and running using
+app_conference with VICIDIAL on Asterisk 1.2.8. I have made several
+modifications to the app_conference code to make it more of a drop-in
+replacement for meetme so that it does not require any changes to the
+VICIDIAL codebase. I have added entry and exit sounds(slightly
+different from meetme's) as well as "only one in this conference"
+message in addition to changing the default member type to speaker(S).
+So far I have tested with IAX and SIP channels only and everything
+works just like on meetme but I have not done any capacity testing or
+tested it in production yet.
+
+If you want to use app_conference instead of meetme for VICIDIAL then follow these instructions:
+
+cd /usr/src/asterisk
+wget http://www.eflo.net/files/VD_app_conference_0.6.zip
+unzip VD_app_conference_0.6.zip
+cd app_conference
+make clean
+make
+make install
