In a VOIP solution, can the Combined publisher / TFTP and Call Manager reside on the same server?

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.

If you don't want to have redundancy,

then no need for clustering and hence all

component i.e call-manager , publisher and tftp can reside on one platform.

I would think the publisher would not be playing a major role here or even be inactive since no

clustering is being done and you're running a stand alone ccm application.

For clustering at its minimum though, you can use two server but three is recommended.

1 server is primary call agent and the second server is the publisher/tftp and secondary call agent.
