Bandwidth considerations

[Sharleen Suarez]

Hi everyone,

Is there a table or a calculator that computes for the bandwidth that a phone take when registering in CUCM over a WAN. The case is that the UCM will be housed in one place and the phones will be in another place. How many phones can a 1MB pipe handle? When calling from one IP phone to another IP phone, will there be transcoding? How much bandwidth would it take?

Would appreciate any answers.

Thanks,

Sharleen

  Take a look at this calculator

In addition, if you look at the SRND for CUCM there is a section on bandwidth calculations for RTP, control traffic etc
