Description (partial)

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

Conditions:
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.
