Hi;
We recently replaced a 2811 router running CUCME 7.1 with a Cisco 4431 running CUCME 10.5, we have migrated the configuration from the old router to the new router. The IP phones on my LAN network registered and works perfectly with the new router.However the IP phones on my LAN can't make phones calls to the Branches where we have cisco 2811 running CUCME 7.1, i have configured the dial-peers pointing the branch router but still can't make calls there, the IP Phone gives an error message " Unkwon Number".
The tricky part is that from the branches they can call on my LAN without any problem.
Has anyone faced this before? Am still new to IP telephony.
