SIPProxy

[DavidTzur1]

Hi, I try to build SIPProxy for IMS and i use the SIPProxy Example. I add to the SIPTransportRequestReceived logic ... else if (sipRequest.Method == SIPMethodsEnum.UPDATE) { logger.LogDebug("UPDATE") }

...

The problem is i don't get the UPDATE request Attach pcap - line 14 is update

Hi, Checking the code in the SIPTransport class, I see that for request with header Required return badRequireResp. I only use as proxy . Why the response is badRequireResp ?

If your application is operating as a SIP Proxy it shouldn't have a problem forwarding UPDATE requests. Are you bale to provide a SIP trace of the traffic into and out of the proxy?

The SIP peer the UPDATE request is being forwarded to might be rejeccting it. It's not a very common or well supported method.

Hi,

This is code from the SIPHeader.cs(line 1762) it Causes the code in SIPTransport class return error

#region Require. else if (headerNameLower == SIPHeaders.SIP_HEADER_REQUIRE.ToLower()) { sipHeader.Require = headerValue;

                        **if (!String.IsNullOrEmpty(sipHeader.Require))
                        {
                            sipHeader.RequiredExtensions = SIPExtensionHeaders.ParseSIPExtensions(sipHeader.Require, out 
                               sipHeader.UnknownRequireExtension);
                        }**
                    }
