Maximum number of IP Phones

[ibarra083]

Hi everybody.

I have installed a Cisco Call Manger 8.6 and I'd want to know how many ip phones can register.

Can anybody help me to resolve my doubt?

A lot of thanks.

Hi there,

You will want to have a look at this whole section of the CUCM

8.6 SRND guide

There are defined maximum supported quantities of endpoints for a given server, as shown in Table 29-5.  Note that these values are guidelines only, and it is possible that the  system may not be able to support these maximum amounts because of  other applications running in the deployment.

Table 29-5     Maximum Number of Endpoints Per Server Platform or OVA Template 

Server Platform Characteristics	Maximum Endpoints per Server or OVA Template	High-Availability Server
Cisco MCS 7845-I3 or OVA equivalent	10,000	Yes
Cisco MCS 7845 (All other supported models) or OVA equivalent	7,500	Yes
Cisco MCS 7835 (All supported models) or OVA equivalent	2,500	Yes
Cisco MCS 7825 (All supported models) or OVA equivalent	1,000	No
Cisco MCS 7816 (All supported models)	500	No
Cisco MCS 7815 (All supported models)	300	No

The designation of High Availability in Table 29-5 indicates whether those servers may be paired for high availability within a cluster consisting of those servers.

Hi Rob,

That was a great information, Correct me if i am wrong, I guess in CCM we have device calculator which gives how many

licence are required, so depending on licence we can get number of devices supported.
