Our organization does a upgrade every 2 years and we will be going to CUCM 14 in 2021 Just trying to plan for the future as we are now dealing with the current list of phones being deprecated. I am currently switching the 7942 and 7962 SCCP devices (that we have) to SIP protocol so we can get a few more years out of those. We were wondering if there was any info out about when the 7942 and 7962 telephones will no longer work. We thought it was going to be possibly with our next upgrade in 2023.
thanks for any and all inpput.
There are no field notices out for CUCM beyond 14 yet. You would need to get an update from the developers directly at this point as to what the road map for future releases will entail as far as device deprecation.
See the Cisco published field notice for which models are being deprecated in CUCM 14. 79X2s are not on the list, but I would expect them to follow in some future release, perhaps 14.5 or 15 (pure speculation on my side).
To answer your other question once the phones are deprecated and cannot be build in CUCM you can certainly add them as 3rd party SIP (assuming SIP load), but their functionality would limited to those devices capabilities.
Have you tried adding a deprecated endpoint as a SIP 3rd party?
From what I know, it would not work and also would not be supported
