Cisco Bug: CSCui95415 - Enhancement to make CUCM send REFER message to transfer calls
Nov 27, 2020
- Cisco Unified Communications Manager (CallManager)
Known Affected Releases
Symptom: CUCM at this point does not use the REFER method in SIP to transfer a call. It uses INVITE and UPDATE messages. This causes extra SIP communication legs in complex transfer scenarios which wouldn't be needed if REFER were used like in Meeting Place or CME. Conditions: Transfer scenario from one SIP party to another SIP party. May or may not necessarily be an inter-cluster call.
