CROSS-CLUSTER COMMUNICATION 2011-05-27
|
|
|
|
|
|
!!!!! THIS FEATURE DOES NOT EXIST, THIS IS FOR PLANNING PURPOSES ONLY !!!!!
|
|
|
|
|
|
This is a planning document for how different vicidial clusters can communicate
|
|
with each other to send various types of information between them. The overall
|
|
goal is to allow for many clusters to talk to each other.
|
|
|
|
Some of the types of communication that we would like to achieve are:
|
|
- Setup of telco trunks(SIP/IAX) allowing for 1-way or 2-way calling
|
|
- Allowing lookup of lead information while transferring between clusters
|
|
- Allow transmission of number of calls in queue and agents available
|
|
|
|
|
|
|
|
--------------------------------
|
|
DATABASE AND ADMIN CHANGES:
|
|
--------------------------------
|
|
|
|
A new options in System Settings will be added:
|
|
- cross_cluster_enabled - Y/N
|
|
- local_cluster_id - the id that is used for this cluster by other clusters
|
|
|
|
This will require a new Admin subsection for cluster configuration:
|
|
- cluster_id
|
|
- cluster_name
|
|
- active - Y/N
|
|
- cluster_primary_server
|
|
- cluster_trunk_protocall - SIP/IAX
|
|
- cluster_agent_api_url
|
|
- cluster_nonagent_api_url
|
|
- cluster_api_user
|
|
- cluster_api_pass
|
|
- cluster_api_permissions - lead_lookup, user_lookup, ingroup_lookup, etc...
|
|
- <readonly auto-updated> cluster_dst, cluster_tz, cluster_local_gmt_now
|
|
|
|
There will be new options added to Servers:
|
|
- local_gmt_now - current calculated gmt offset
|
|
- cluster_id - default will be LOCAL cluster
|
|
- cluster_call_direction - IN_FROM_CLUSTER, OUT_TO_CLUSTER, BOTH, NONE
|
|
- cluster_server_ip - SERVER_IP, ALT_IP, EXTERNAL_IP
|
|
|
|
There will be a new table added to link lead_ids on clusters:
|
|
-vicidial_list_cluster_link
|
|
- lead_id
|
|
- cluster_id
|
|
- cluster_lead_id
|
|
- call_date
|
|
- caller_code
|
|
|
|
Some tables will have a "cluster_id" field added to them to show where the call came from
|
|
- vicidial_auto_calls
|
|
- vicidial_campaign_stats
|
|
|
|
|
|
|
|
--------------------------------
|
|
NON-AGENT API CHANGES:
|
|
--------------------------------
|
|
|
|
lead_id_lookup:
|
|
- REQUIRES: cluster_id, caller_code
|
|
- RETURNS: all lead and call information
|
|
|
|
lead_notes_lookup:
|
|
- REQUIRES: cluster_id, lead_id
|
|
- RETURNS: call history for lead_id including per-call notes
|
|
|
|
ingroup_status:
|
|
- REQUIRES: cluster_id, group_id
|
|
- RETURNS: number of agents waiting/incall/paused/total, number of calls waiting, calls today, drops today, drop %
|
|
|
|
campaign_status:
|
|
- REQUIRES: cluster_id, campaign_id
|
|
- RETURNS: number of agents waiting/incall/paused/total, number of calls waiting, calls today, drops today, dialable leads, drop %
|
|
|
|
cluster_server_status:
|
|
- REQUIRES: cluster_id
|
|
- RETURNS: listing of defined servers, their current times as well as PHP and DB times
|
|
|
|
|
|
|
|
--------------------------------
|
|
CALL FLOW AND TRUNK CHANGES:
|
|
--------------------------------
|
|
|
|
- IAX/SIP trunks would be added between every server on every active cluster(depending on direction settings)
|
|
- dialplan context would be added for each foreign cluster to route calls with proper cluster_id flag allowing for lookups of lead information
