Registration to CCM

[elp]

Is there any limitation on registering multiple SIP AoRs on the CUCM with a single source IP address and TCP port?

The restriction depends on CCM Server model not multiple SIP AoRs.

Hi,

Can you elaborate a bit further? Just to clarify the question a bit, let's suppose that I want to register 3 SIP phones (Let's assume extensions 3001, 3002, and 3003) as SIP line devices on the CUCM, using the same IP address (i.e. 192.162.1.1) and the same TCP source port (i.e. 5060).

Did you imply that it depends on the CCM version I'm using? If so, do you know which version would allow such behavior?

Thanks!
