Cisco Bug: CSCui96679 - SBC No Way Audio on Transfer calls traversing more than two SIP trunks
Apr 17, 2019
- Cisco ASR 1000 Series Aggregation Services Routers
Known Affected Releases
Symptom: On a Cisco ASR1k running the Cisco CUBE SP (Service Provider) feature set, IOS-XE version 15.1(3)S1, it is sometimes observed that a specific call transfer will have no way audio (dead air) upon the transfer completion. Conditions: The CUBE SP has at least three physical interfaces that terminate three different SIP trunks (for example to ITSP, SIP based IVR and to a Cisco Callmanager) and the problematic transfer call flow signaling traverses all three SIP trunks on the same CUBE.
