If you are still having this problem, you need to add the following on your configuration:

voice service voip
 sip
  registrar server expires max 600 min 60

Let me know if that works...it did for me. After debugging registration, the phone was  looking to register to the server.

Hey;

try this and please let me know if it fixed;

Voice register pool  1
 busy-trigger-per-button 2
 id mac xxxx.xxxx.xxxx
 type 7821
 number 1 dn 1
 presence call-list
 dtmf-relay rtp-nte
 codec g711ulaw

session-transport tcp 

and go to "voice register global"

create profile

if problem still active please attach "debug tftp events" and status messages from an ip phone maybe you can take a pic of screen

Good day

Hello Adnan,

I am facing same issue in CME 10.0.

How did you ended up with your problem ?

Hi Ilana!!

As I explained on another similar case... after one week testing (and fighting) with Cisco TAC, they accepted my RMA requirement of the SPIAD Router.

Once I received and installed the replacement router, all phones registered !!!! Including a new CP-8831 !!

If you have a SPIAD Router, with similar strange behavior i really recommend you to require a RMA.

I HTH
