Well, I am not sure whether this discussion belongs to here or to the dev list, or maybe somewhere else but I still press on. :-)
"You may want to check out the design document. Please download the source code from svn and look at sipXbridge/doc/design.tar.gz"" Thanks for the pointer, it is a very useful material. I am looking at the outbound-blind-transfer-to-pbx scenario. First, I found strange messages like this: Time: 2009-01-03T19:24:36.701000Z Frame: 31 /tmp/trace.Risq9235/_.sipxbridge.trace.xml:968 Source: sipxtest.example.local-sipXBridge Dest: 81.144.230.5:5060 INVITE sip:[email protected]:5060;transport=udp SIP/2.0 CSeq: 2 INVITE Call-ID: 94befed0-c0a805ed-13c4-2872c-32686d2b-28...@sipxtest.example.local.0 From: "user4" <sip:[email protected]>;tag=8002033480187804211 To: <sip:[email protected]>;tag=SDl7pu599-621570258 Max-Forwards: 70 Allow: INVITE,BYE,ACK,CANCEL,OPTIONS Via: SIP/2.0/UDP 192.168.5.75:5080;branch=z9hG4bK46dc16e777498a3b9562fe4e92073abb Contact: <sip:[email protected]:5080;transport=udp> Accept: application/sdp Content-Length: 0 What are these for? These seem to be proxied "hold" re-INVITE requests from the Nortel 6812 desk phone but where is the body. The second, more interesting question for me, what do the parties in question hear when the transfer is in progress. My understanding is the both the source and target1 call legs are established, therefore 183 or 180 messages without SDP cannot be proxied in any way. Therefore if the REFER target is a deskphone (that often does not produce early media for ringing), no party in the call (Source, target1) will hear ringing while the transfer progresses. Am I missing something?
