IMG 1010 - Call Release Origin in CDR
- Kelli Higdon
Overview:
A problem that arises when troubleshooting a failed called is knowing where the call release came from. The IMG however has the functionality to inform the user whether the release came from the IMG (local) or the release came from the remote party (remote). When a call fails, the release information is written into the Call Detail Records (CDR) in RADIUS. The Call Party Release Info in CDR feature will display one of the following in the Radius CDR "dialogic-release-source"
CALLED PARTY RELEASE - Local
CALLED PARTY RELEASE - Remote
CALLING PARTY RELEASE - Local
CALLING PARTY RELEASE- Remote
Example CDR:
The example below displays that the destination channel group of the inbound call does not have any free channels available so the IMG releases the call. In the CDR below it displays  dialogic-release-source = "CALLED PARTY RELEASE,Local" meaning the release came from the local party.

Release Scenarios:
Below are examples of calls being released and what would be displayed in the RADIUS CDR
CALLED PARTY RELEASE - Local
All channels in outgoing channel group are out of service.
dialogic-release-source = "Called Party Release - Local"
dialogic-Q931-disconnect-cause = "22"
IMG timed out waiting for Alerting from destination network
dialogic-release-source = "Called Party Release - Local"
dialogic-Q931-disconnect-cause = "12"
CALLED PARTY RELEASE - Remote
User busy
dialogic-release-source = "Called Party Release - Remote"
dialogic-Q931-disconnect-cause = "11"
Unallocated number
dialogic-release-source = "Called Party Release - Remote"
dialogic-Q931-disconnect-cause = "1"
CALLING PARTY RELEASE - Local
No match in incoming translation table on IMG. Un-allocated number
dialogic-release-source = "Calling Party Release - local"
dialogic-Q931-disconnect-cause = "1"
No match in route table on IMG. No route to destination
dialogic-release-source = "Calling Party Release - local"
dialogic-Q931-disconnect-cause = "3"
CALLING PARTY RELEASE - Remote
Normal call clearing
dialogic-release-source = "Calling Party Release - Remote"
dialogic-Q931-disconnect-cause = "16"
If the call is released internally by any signaling layer, the reason will indicate remote. This is being worked on and will be fixed in a future release. Until the issue is fixed, further analysis will be needed to determined the origin. For example viewing call traces.
