Cisco Bug: CSCsz48623 - SIPD isn't calling updateSrtpFallbackSupport for SIPAlertInd
Jul 06, 2017
- Cisco Unified Communications Manager (CallManager)
Known Affected Releases
Symptom: Fallback to RTP might not work while CUCM interworks with PGW - leading to call drop. Conditions: Fallback to RTP fails when PGW sends a 180 with SRTP offer SDP to CUCM. CUCM fails to recognize the Supported:x-cisco-srtp-fallback header in 180 response. This causes the call to drop if the originating CUCM endpoint is RTP only.
