Hi!
I've been looking at FS source code and realized that at least the invite_contact can be changed by declaring the contact-user, ext-sip-ip and ext-sip-port profile variables.
I would like to know what other option do i have to change contact(all the sip_uri string) in the different stages of a call: REGISTER/INVITE/SESSION_IN_PROGRESS, ACK, OK, etc...
I would also like to be able to change contact in runtime dynamically, what option do i have in this case?
