Upgrading/downgrading CP-7841=k9= ver 9 phone to MPP version tftp

[Osdieman]

Hello All..

I have a question on how to up or downgrade my 4 brand new CP-7841-k9=  ver.9  phones to work with 3e party sip providers.

i did manage to upgrade the phones via tftp but no way i get an MPP version loaded in the phone..

Can somebody tell me what to do..?

Kind regards Osdieman

A license, L-CP-E2M-78XX-CNV, to convert the phone to 3PCC/MPP is mandatory.

Hi Leo .. thank you for replying me..

Does this means i have to buy this license and then migrate using the cloud ?

Sorry for these noob questions.. but i am totally new in cIsco phones.. and i have only 4 of these devices...

So not sure if it is worth to migrate them  to MPP firmware or not.. ))

One license per MAC address. 

If there are 4 phones, then 4 licenses will need to be purchased.
