[SIPForum-discussion] 302 message question

[Mihaly Zachar]

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 can't find it in the RFC 3261 who has the truth..

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
