Well, a lot depends on how the remote SIP terminal is coded. If for
instance, it does a UDP connect() to 10.0.0.1 and then a send() to send the
INVITE request and a recv() to get the responses, you maybe out of luck
since it is expecting the responses on the connected socket to 10.0.0.1 and
not 10.0.1.1.
Is it possible for you send a 200 OK over the internal bus to 10.0.0.1 and
have it send it out to the remote SIP terminal?
