Hi Inaki,
Then what should I do if I get the following error: SIP/2.0 481 Call Leg/Transaction Does Not Exist
When both caller and callee are online?
And why do you assume that it's a fail related to the "To" header?
RFC 3261 21.4.19 481 Call/Transaction Does Not Exist
This status indicates that the UAS received a request that does not match any existing dialog or transaction.
Also read how a UA tries to match an incoming request to an existing transaction: http://tools.ietf.org/html/rfc3261#section-17.2.3
WeSIP receive the request with the real From uri but the To uri contains the IP of openser server. Is this the correct situation?
Sincerely, you should read the RFC 3261 to understand that the "To" header is usually not examinated by the UAS, just the Request-Uri. But you cannot asumme something incorrect without reading about it and later ask "then what?".
