Is there a mechanism in SIP to allow for user defined fields to be sent along with a SIP message.
Specifically I would like to periodically send some user defined fields with the re-INVITE (keep alive)
method from my SIP phone. I am assuming that the VoIP provider is able to deal with the parameters
in some proprietary way. I would be grateful for any pointers. Thanks.
