Setting up a SIP Trunk from Asterisk to Cisco

Hi -

I want to make external calls from Asterisk. I have a CISCO router that is connected to providers through whom I can make external calls.

Please tell me the method to create a trunk from Asterisk to Cisco so that I can make external calls.

Any help is highly appreciated.


This is the wrong forum for support questions.

You subject implies you are using CUCM, but the body suggests you are using some sort of router with limited SIP capabilities. You need to be more precise.

From the Asterisk side, when connecting to CUCM, a standard, unauthenticated trunk configuration works.
