OUTBOUND DIALING OPTIMIZATIONS DOC Started: 2016-11-15 Updated: 2016-11-15
|
||||||
|
|
||||||
|
|
||||||
|
This document is a work in progress and is meant for reference only, to go over approaches to optimizing and speeding up the outbound auto-dialing processes
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Places to look at for speeding up outbound auto-dialing call routing speed:
|
||||||
|
1. Checking for Local/ channel resolution
|
||||||
|
2. Database load and query speed
|
||||||
|
3. AGI script compilation and execution time
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
SECTION 1. LOCAL/ CHANNEL RESOLUTION
|
||||||
|
|
||||||
|
First, and explanation of what exatly the "Local/ channel resolution" issue is. Auto-dial calls are placed from VICIdial to Asterisk using a Local/ channel, which goes to the dialplan and places the calls out through a carrier. When the call is placed, there is no audio stream yet, only signalling, and it stays that way until after the Answer signal is received from the carrier. At that point, the Local/ channel will resolve to it's proper channel pointer(usually SIP/... if using a sip carrier). Where the issues come in, is how long it takes for the audio to begin being received so that the channel pointer can resolve. This is extremely variable, and depends on the end customer carrier, as well as all of the carrier equipment in-between. We ahve seen Local/ channels resolve anywhere from 0.1 seconds up to 2 seconds, and in a small percentage of cases, the channel never resolves because no audio stream is received.
|
||||||
|
|
||||||
|
Currently, the outbound call agent routing process will immediately attempt to route the call if the Local/ channel has been resolved, and if it isn't, it will wait 1 second before trying again, then if it is still not resolved, giving up and logging the call as LRERR status. The optimization we are trying in the BETA script is to try multiple attempts at much faster intervals to check for Local/ channel resolution. The compilation of the AGI script can take anywhere from 0.1 to 0.3 seconds, depending on the server hardware and system load, then if the AGI script detects a Local/ channel, it quits and is tried again immediately. This also allows for a longer amount of time to wait for the channel to resolve because the number of loops is adjustable.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
SECTION 2. DATABASE LOAD AND QUERY SPEED
|
||||||
|
|
||||||
|
Basic my.cnf and proper hardware optimizations. Nothing further yet.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
SECTION 3. AGI SCRIPT COMPILATION AND EXECUTION TIME
|
||||||
|
|
||||||
|
This section goes over the option of stripping down the AGI routing process(agi-VDAD_ALL_outbound.agi) as much as possible to improve the speed of routing outbound auto-dialed calls.
|
||||||
|
|
||||||
|
The following features could safely be removed and still allow for basic outbound call routing functions within the AGI:
|
||||||
|
"LO" agent search method(try to route to agent on dialed server first, not used in default configs)
|
||||||
|
CPD AMD, Sangoma call progress, answering machine detection
|
||||||
|
QueueMetrics logging
|
||||||
|
concurrent transfers if set to AUTO
|
||||||
|
extension append CIDname
|
||||||
|
grade random next-agent-call routing
|
||||||
|
reminder message, play only
|
||||||
|
remote-agent call routing
|
||||||
|
routing initiated recordings
|
||||||
|
survey recording
|
||||||
|
survey, play message and wait for dtmf response
|
||||||
|
text-to-speech survey
|
||||||
|
inactive trigger process
|
||||||
|
|
||||||
|
Removing these features will result in the removal of over 65% of the code in the AGI script. This should greatly improve both perl interpretation time and reduce RAM usage, but might not have a very significant effect on execution time due to all of these removed code segments being enclosed inside of "if" statements that aren't run unless those features are activated anyway.
|
||||||
|
|
||||||
|
Testing this change will require either NOT removing the "remote-agent call routing", or testing on a production system that does not use remote-agents.
|
||||||
|

||||||

Added vicidial_vdad_log table to store debug and timestamp data(examples below). To enabled this level of logging in the BETA script, you must run the following SQL statement:
|
||||||
|
|

|
update system_settings set vdad_debug_logging='1';
