CONNECTING IP PHONES REMOTELY

[meyofmarksog1]

Hi Engineers and experts,

I have been working on a project. i decided to simulate(packet tracer 7) a network with several branches. I am stuck with the configuration of voice. the cloud is a router that does routing. i used EIGRP as routing protocol. i have been able to get them communicate within their branches. but they cannot communicate outside their WAN links with the other branches. What advise can you give me?

You'll have to more specific, this seems to be more of a routing problem than a VoIP problem.

VoIP just assumes you'll have all your routing configured to have the IP Phones reach your CUCM server, and the ability to route the RTP directly between endpoints, and have QoS if required so voice has the right priority.

To enable the various VOIP phones to communicate i configure several "dialer-pairs" with other branches.

it was a mesh approach. i wonder if there is a better way to do the configuration.
