[SR-Users] Register Transaction Callback function

[Bruno Bresciani]

Hello,

I have no a valid sip msg struture on my functions exported. I want get
only the call-id of specific transaction created by t_relay() (or other tm
functions such as t_newtran()). If I understood, I have that declare a
global sip msg struture and give it to function register_tmcb?

Cheers,
