Nortel PBX’s running on a Cisco Network

Locked

I have a Nortel voice network that is running across a new Cisco network. I am having some clocking issues on the Nortel Option 11’s running through the Cisco 2811’s. Any advice

Check to see if the T1 is clocking off of the Nortel in your Opt 11. If so, change it to clock off the vendors T1 clock.
