sip trunk

[reidg]

basically how many calls can you get across a sip trunk. We're looking to connect to a mitel 3300, and the mitel chaps are talking about individual licenses for each trunk i.e. call. Whats the case with the cucm 6.1. how many can it handle, is there any license issues?

thanks in advance

There is no license for this currently, the limit is the bandwidth.

Hello,

As stated by Chris, there is no restriction on the CCM side. The following doc contains additional information regarding SIP trunks:

Hope this helps!

Because a SIP Trunk is not a physical connection, there is no explicit limit on the number of calls that can be carried over a single trunk. Each call consumes a certain amount of network bandwidth, so the number of calls is limited by the amount of bandwidth that can flow between the IP PBX and the provider's equipment.

For marketing reasons, many providers associate a SIP Trunk with a single phone call. When you purchase such a SIP Trunk, it provides the ability to place one call at a time through the service provider's network. Organizations purchase as many trunks as they need to support their specific needs,typically one trunk per 3-5 employees. Some providers allow several calls to be carried over a single trunk

thanks for the responses guys most helpful, just to be clear, from a cucm perspective no limitation on the sip trunk, set up a trunk and yuo'll get as many calls across it as the bandwidth and/or other system allows?
