Hi all,
I am facing a big problem, I made a trunk between Asterisk and Mitel,and I have two users calling each other, one on mitel and the other on asterisk.
when I make the trunk call I attach custom SIP header to the SIP invite message
but when the message is recieved to the Mitel User its without the SIP header.
How can I fix this problem.
the Asterisk connects to Mitel Gateway.
thank you
