UCM - minimum BW between servers & endpoints

Unanswered Question
May 12th, 2009

Hi all,

I have a question related to UCM server that needs discussing from you:

What is the minimum BW (and what is the maximum delay) between the server and the endpoints.

I have such the question because we have some remote sites that connect to the central site via 128kbps links.

Thanks,

I have this problem too.

The maximum one-way delay between any two Unified CM servers should not exceed 20 msec, or 40 msec round-trip time (RTT). The minimum recommended bandwidth between sites that are clustered over the WAN is 1.544 Mbps.

Thanks for reply.

But your answers didnot solve my question! My question is "the minimum bandwidth between the CCM server(s) & the endpoints (IP Phones)).

Any other?

Thanks,
