Cisco 8821 IP Phone Fast Track Setup in CME 11.6

Hello Everyone,

I am trying to get a Cisco 8821 IP Phone to register with a Cisco 2951 ISR running 15.6(3)M1, which gives me CME 11.6.

The Cisco 8821 can only be registered via Fast Track in CME as full support isn't currently in the platform. The problem I have is that whilst I can get the phone to download it's firmware, and retrieve it's SEP007686CEB212.cnf configuration file, it doesn't try to register with the platform.

The following is my configuration:

tftp-server flash:dtblob8821.HE-01-005.sbn
tftp-server flash:fbi8821.HE-01-008.sbn
tftp-server flash:kern8821.11-0-3-6.sbn
tftp-server flash:rootfs8821.11-0-3-6.sbn
tftp-server flash:sb28821.HE-01-019.sbn
tftp-server flash:sip8821.11-0-3-6.loads
tftp-server flash:vc48821.11-0-3-6.sbn

As far as I can see, the handset can get the generated configuration file and it takes the password set under the username/password section of it's config so it is taking some bits of the config. It doesn't ever set it's line though, that remains greyed out on the phone.

From the handset I can see it complain about not being able to download the locale file, but I'm hoping this isn't an issue.

Has anyone managed to get an 8821 registered on CME?

Cheers,

James

Hi James,

Can you add bind command under voice service voip > sip > bind.

Also, please share the output of 'debug ccsip message' to see what errors are taking place during registration.

Thanks Mohammed, you had the right idea. Turns out the loopback interface that the customer had bound the media and signalling to was non-routeable from the voice VLAN.

Rebound now to a valid interface and the handset has registered without issue. For some reason I can't see your comment to mark it as correct, but trust me you were right.
