Phone continues to not register in CME

[John Cheetley]

Hi again Cisco techs,

Me again. 7912 cisco phone fails to register in cme 3.3 via IOS 12.4(25d)(C2691-IPVOICEK9-M),

I reset the phone to factory reset. Then done 

cme_router(config)#telephony-service
cme_router(config-telephony)#load 7912 CP7912060000SCCP050124A.sbin
Updating CNF files
CNF files update complete

cme_router(config-telephony)#reset all
ITS configuration has been changed, selecting sequence-all reset
Reset-All: no active phones
All DNs in DOWN state

Phones MAC address and extension number shows in CME 3.3

Can ping phone OK but not register as below command states

cme_router#sh ephone

ephone-1 Mac:0017.9570.8E67 TCP socket:[-1] activeLine:0 UNREGISTERED
mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:1
IP:0.0.0.0 0 Unknown 0  keepalive 0 max_line 0

cme_router#

I know that persistance pays off but this is driving me crazy.

Can someone please advise

Did you change default-router and option 150 ip in your DHCP config yet? Still showing as 0.12

Hi Michael,

That has worked. This is so "cool". The phone has "finally" registered. Wow. What an awesome moment. Tried to make a phone call. Has a tone on the line but called local number to nothing. Have to troubleshoot.
