I''m designing a small VOIP network, 6 remote sites via T-1 WAN, 2-3 phones/site and a centralized call manager. Redundancy is not an issue, and there is no need for a PSTN access. The network is a totally closed IP WAN. Every reference I''ve found so far describes Call Manager clustering and recommends that the Combined publisher /TFTP and the Call Manager reside on seperate platforms. My question is: Is it necessary to have seperate platforms in a small implementation.
The WAN is an MPLS backbone through Worldcom's VBNS+. I understand the risks of a non-redundant voice system, however, this implementation is just going to be a small model as a proof of concept. If it goes onward to a much larger scenario, then, redundancy will come into play. For this run through I will be using an MCS-7835 for the call manager and I wasn't sure if the database and TFTP server could be colocated in the same device. I'm assuming it can.
We are running 3.0.11 on three CM. One CM is for the home office, one is for our remote offices and the third is a backup for the home and remote offices. We have TFTP running on all three for backup and load balancing purposes. We have 200 phones in the home office and a total of 100 for the remote offices. We have not seen any degradation with TFTP loaded on the CM's. Also, each server should be able to handle up to 4,000 phones with the newest CM loads.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
