I need to connect 32 7940's at a branch office. I have a 10mb LES circuit between the head office and the branch. The call manager and Voice gateways are at the head office. My question is will the 10Mb be enough for 32 phones? I am planning to run layer 3 between the offices. What compression will work best?
That should be plenty of bandwidth depending on your current data traffic. A G.711 call consumes 64k plus overhead for headers, etc. CallManager allocates 80k. The normal best practice is to use G.729 over the WAN which reduces the per call bandwidth to 8k plus overhead. CallManager allocates 24k for calls using this codec. I'm not sure what your data traffic looks like, but I'm guessing you could get away with using G.711 and get improved quality. Also, you can use Call Admission Control to limit the amount of bandwidth consumed by voice traffic and Quality of Service mechanisms to prioritize this traffic.
As already mentioned, you should have adequate bandwidth to support G.711 (is that 10megabyte or 10 megabit?). Also keep in mind that traffic between the remote phones doesn't need to traverse the link - just the call setup info. Depending on your situation, you might never see more than 10 calls on the wan link at any given time. Biggest issue I see is enforcing priority or QOS on the traffic so someone doing an ftp doesn't stomp on the voice traffic.
