Hi,

I want to know what should be the behaviour of UAC after receiving 180 
response when dialog is already in confirmed state.
I think it should process it, is this behaviour mentioned anywhere in RFC?

This scenario can occur in prepaid calling card application where user A 
first calls B, and after finsihing talking, he calls another user C on the 
same call.
To connect user C, we can send Re-invite to user A agent resulting in call 
connected between A and C as per thirdparty call control.

But before the call is answered by user C, if 180 Ringing is send to user 
agent A, it should play ringback as user need to hear the ringback to know 
the status of the second call.
