Can a CP-6921-C-K9 phone be used as a third party SIP device on CUCM 6?
We will be upgrading soon to a new version of CUCM where 6921 would be supported but for now can we get them to work on CUCM 6 as SIP phones?
It looks like the SIP support is even later in the 7.1.x line. No documented operation as 3rd party SIP that I can find.
The phones are supported in Cisco Unified Communications Manager and Cisco Unified Communications Manager Business Edition Versions 7.1.2 and later using Skinny Client Control Protocol (SCCP) or SIP with Cisco Unified Communications Manager and Cisco Unified Communications Manager Business Edition Versions 7.1.5 and later.
yes I found the same information about SIP support in 7.1.X but was wondering if anyone had tried to connect the phones as a third party SIP phones in CUCM 6. I don't see why it should not work but there is no way for me to test this now.
