From: Mihaly Zachar <[EMAIL PROTECTED]> 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. I believe the developers are incorrect. In RFC 3261, section 13.1, top of page 78, we see: After some time, those UASs can accept the invitation (meaning the session is to be established) by sending a 2xx response. If the invitation is not accepted, a 3xx, 4xx, 5xx or 6xx response is sent, depending on the reason for the rejection. Before sending a final response, the UAS can also send provisional responses (1xx) to advise the UAC of progress in contacting the called user. After possibly receiving one or more provisional responses, the UAC will get one or more 2xx responses or one non-2xx final response. This text implies that a provisional response may precede a non-2xx final response.
