Trunk between UC-540 and Cisco 2811 CCME


recently we have installed a UC-540BRI to a customer. The customer also has a Cisco 2811 CCME connected through a Primary Line to the their public telephone provider.

I would like to know if it's possible for the UC540 to accept and place external calls through the 2811 and its primary line.

Thank You

Is there IP connectivity (WAN/LAN etc.) between 2811 and UC540 ?

If yes, then its simply a matter of configuring voip dialpeers to send

calls between the two according to ur dialplan requirements.

Hi There,

If you have IP connectivity between these 2 devices then you can definately do this. If you are using analog lines at each location with no IP connectivity then this cannot be setup with this type of connectivity.

Please post your network diagram and configs or provide a more indepth  explaination of your solution so that we can provide accurate  information pertaining to your solution.

HTH, Please rate if so

there is IP connectivity through a set of wireless bridge.

I will post network diagram and configs (UC540 & 2811CCME) in a couple of days.

Thank you!
