Ip phone 8831not registering

[ing_ivandez]

Hello engineers

I have a problem with some IP phone 8831 that are not registering because of a wrong firmware.

Could you tell me which is the right firmware for this?

I have this version:

                     CUCM 9.1.1.20000-5

Best regards!

are you registering phones as SCCP or SIP?

Hello Nadeem

Thank you for your quick answer. Phones are registering as SCCP, I have uploaded the pack cmterm-devicepack9.1.1.21026-1.cop.sgn, but it gives me the nexte error:

Major, minor and maintenance version numbers obteined from the name do NOT match those of the current version.

any idea?

I was refering some data sheet and rls notes, This is SIP phone and you are registering as SCCP, possible reason that its not getting register.
