[VoiceOps] Has anyone seen this? Voice UCaaS application on iPhone generated call: switching source IP address mid-call with no SIP signaling to indicate

[Richard Jobson]

Just curious as to whether the community thinks this is a network configuration issue or a Mobile app issue


This is either …

1.        Something to do with the app on the iPhone
2.       Or is the Wireless IMS Network SBC that is changing the srce IP Addr mid-call
3.            Or RTP has been routed to a different Wireless IMS Network SBC mid-call

this behavior is totally noncompliant to the RFC.

The Oracle SBC in our ITSP network maintains the call up because the SSRC remains the same. However, when this happens, a second or third time it gets complicated .

Many Thanks & Best Regards,
