RTCP Collector + Outbound Proxy

[Bryan Nelson]

Thank you Flora.

This makes sense - RTCP is a normal SIP Publish packet, so it will follow the rules you set for the proxy.

It just happens to be inconvenient for us at the moment. I'll update once I test the BLF failback on v73.

* Update - It appears that the outbound proxy is still required on v73 for BLF subscriptions to return to the primary server after a failure. Without it, the BLF subscriptions remain on the secondary server while the main registration returns properly.
