Hi all,

I'm writing an UAS.

The UAS has a feature, that if the called number is matching with a pattern, it will send 183 Session in progress, than plays an RTP stream and then redirect the UAC with 302 Moved Temporarily..

There is an UAC, and it's developers says that I should not send 302 Redirect after the 183 Session in progress.

This solution works well with CISCO media gateways.

I could not find the exact paraghaph about it in the RFC 3261.

Can sy help me in this ?


So, the call flow is the following:

UAC                      UAS
    --- INVITE --->
    <--- 100 ------
    <--- 183 ------
    <-- RTP --
         .
         .
         .
    <--- 302 ----


Is this correct ?


Thanks,
Misi
