Call Party Release Source in RADIUS CDR

A problem that arises when troubleshooting a failed called is knowing where the call release came from. The IMG 2020 however has the functionality to inform the user whether the release came from the IMG 2020 (local) or the release came from the remote party (remote). When a call fails, the release information is written into the Call Detail Record (CDR) in RADIUS. The Call Party Release Info will display one of the following values below 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 2020 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"

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. Un-allocated number.

dialogic-release-source = "Calling Party Release - local"

dialogic-Q931-disconnect-cause = "1"

No match in route table. 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.
