12.4(5.11) 12.4(5.11)T

Description (partial)

Symptom:
Other SIP endpoints send SIP signaling to the gateway's source port.  By default, this is an ephemeral port.  

Conditions:
This command is used to solve the problem:

sip-ua
 connection-reuse

However, this is a hidden command and customers, partners, and other parties that work with SIP gateways are unaware of this capability. Without proper documentation, we are unable to give customers accurate information about the implications of the command.  It it widespread enough to justify fully supporting the issue as it is one of the common interoperability problems with the gateway.

This can be compared to other products like CUCM which have the opposite behavior, and use the same source and destination port.
