Hi Don,<br><span class="content"><p class="pB1_Body1"><b class="cBold"><span style="font-weight: bold;">E</span>quation 1:</b> Recommended Bandwidth Needed for Control Traffic without Signaling Encryption.

Bandwidth (bps) = 265 <span style="font-family: Symbol; font-style: normal; font-weight: normal;">* </span>(Number of IP phones and gateways in the branch) <br></p>Plus you need to plan for your RTP streams (audio).. but this depends on alot of things like where those phones are going to be talking to, what codec you are using, etc - so theres not just 1 formula.
<br><br>There are also other things to consider besides just the bandwidth.. example latency for the control traffic, packet loss/latency/jitter for the RTP traffic. The SRND documents are a good starting place. <a href="http://www.cisco.com/go/srnd">

I'm working on a project to give VoIP services with a CCM located<br>outside of the office... in fact at a different country. Does naybody<br>knows how much BW do I need at the CCM site for a 300 IP Phones<br>community?
