[Users] Is there some functions which can append parameters for specific header field?

[杨冬]

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.
