Registration telephone SPA508g on CME

[damjankosir]

Hi all,

I have Cisco telephone SPA508G. I want registration this telephone by SIP on Call Manager Express v.8.1.

SW on a phone is SPA50x-7-3-7. Do you have any idea how can I registration this phone to CME?

Phone gets ip address but I could not set username and password?

Are you registering to a UC5xx?  These phones are only supported on the SBCS CME platforms.

You may get it working by registering it to SIP CME on an ISR, but it's technically treated as a third party SIP phone to CME, which isn't a supported solution.  ISR CME phone supported phone list is here:
