I have a problem to configure a trunk SIP on my CCM 4.2 SR3.
There's no problem to configure SIP trunk on Asterisk, but to configure this on CCM, you must before configure a MTP (Media Termination Point) on CCM.
However, I can't do this because I can't add a new MTP on CCM because I can't the IP adress of my asterisk on cisco. How can I do ?
In Host server, it tell me "not selected"
If you have an idea.
