hi, all: I've got such a problem recently. For our SIP client test, I must simulate a specific 180 message. There is a user-defined parameter in the Contact header field. I want to construct this message in openser server when it forwards the message to the caller. So I wonder there is some functions which can append a string parameter to the Contact header field. If it does, I can just add a process script into the configuration file of openser.cfg. Can anyone give some suggestions? Thanks.
