No luck … I followed this post - **Solved**How to create IP based authentication with two Asterisk servers using FreeBPX but still no joy.
Here is my peer config;
disallow=all allow=alaw canreinvite=no dtmfmode=rfc2833 host=172.22.4.123 insecure=invite,port port=5060 qualify=yes type=friend
Not working, I’ve put that in USER as well to try that. Tried insecure=yes|invite|invite,port|very - no luck. Asterisk always replies to anything from CUCM with 401 auth challenge…
