CUCM 7.1(3b) and Maximum supported SIP trunks/Port Numbers

Answered Question

Needed to know what is the maximum number of SIP trunks supported on a CUCM 7.1.3b server and/or cluster.

Also, can the SIP trunks be incremented by port number (I know 5060 and 5061 are reserved) - for example, using the same IP address to another 3rd party SIP device, but needing additional SIP trunks to the same server/IP - can I just increment the SIP port numbers?  And if so, how many trunks (Port numbers) can I support to a single IP address?

Thanks.

I have this problem too.

A cluster consisting of MCS 7825 or MCS 7835  servers can support a maximum of 600 H.323 devices (gateways, trunks,  and clients), digital MGCP devices, and SIP trunks.

A cluster consisting of MCS 7845 servers can  support a maximum of 2100 H.323 devices (gateways, trunks, and clients),  digital MGCP devices, and SIP trunks.
