[Asterisk-Users] Transferring calls - BUG0003710

[Douglas Garstang]

Olle,
 
xxx.187.142.20 is a phone (not sure if it's the caller or callee)
xxx.187.142.203 is an OpenSER system, which sits in between the phones and Asterisk.
 
I guess OpenSER must be changing the callid when it forwards SIP messages to Asterisk. It's surprising that no one else seems to have encountered this problem, as a lot of people use OpenSER, as we have done, to get around some pretty serious limitations with Asterisk.
 
Why on earth is OpenSER's ip address in there anyway? It's not in the RTP path. Asterisk should have the phone's IP address in there. It's a little like SIP subscribe/notify messages. Asterisk sends notify messages back to OpenSER, where the SUBSCRIBE's came from, rather than sending them directly to the phone. Why is that?
 
Arrgh.
 
Doug

	That call may be on another server - your sip show channels confirm 
	that it is not on this server.
	The error message clearly says that both legs must reside on Asterisk 
	box...
