Call Manager capacities

v-yelmene · ‎06-26-2007

can someone point me in the right direction? I need a Call Manager that can handle 100-200 IP phones. We need the accounting and CDR details from the Call Manager for chargeback, otherwise we would use Call Manager Express.

thanks

You can start with a 7815/16 which can handle up to 300 phones but only two servers in the cluster. I would also recommend going to the Callmanager Business edition which has callmanager and unity connection built into one server. Right now there is no redundancy from a server standpoint, but this is in the roadmap. Note that Cm 6.0 has not been out there for long, so you may want to watch out on what kind of bugs you will run into before buying one of these.

I would go ahead with a 7825 for a min. This can handle up to 1000 devices.

Use callmanager capacity tool for sizing.
