Description (partial)

In very rare scenarios, embedded IP addresses in SIP packets may not get fixed up as expected.

This was first identified on an ASR1K running 15.1(3)S3.
The soft switch inside had static PAT configured for tcp and udp port 5060 to a mapped IP address A.
The same soft switch on the inside also bridged media and ASR was configured with dynamic PAT overload to a mapped address B.
Inbound and Outbound connection must be configured to use different mapped IP address.
