[Users] Call-ID discrepancy

[Sam Lee]

Because of this , it causes a problem for my RTPproxy.
My RTP proxy reference the same dialog by the call-id , so if it is
different from the initial call-id, the entire dialog will be
interpreted as 2 separated sessions and RTP ports allocated differently.
The end result ? , one way voice.

Is this kind of behaviour correct ?

I have actually seen an ALG do exactly that before, and my client
dropped all messages coming back through it, as expected.
