Phone continues to not register in CME

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)#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 Unknown 0  keepalive 0 max_line 0


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

Can someone please advise

michael o'nan

try no create cnf-files

create cnf-files

see if that gives you anything different

Thanks Michael. I had tried that already. Much appreciated though

post the output from "debug tftp event/ debug tftp packet", when you reset the phone, and lets see what happened, trust me the above command is very helpful when troublshooting CME phone registration.

What phone is displaying on its screen ? can you attach cme config (You can remove ip details).

Otherwise try to reconfigure ephone with different ephone tag and attach "debug tftp events"


Phone goes into a constant loop of:-

Configuring vlan, configuring CM List, then configuring IP

Switch can ping router/tftp(same IP address)

Can ping phone from router ok.

CME configuration is:

cme_router#sh telephony-service
CONFIG (Version=3.3)
Version 3.3
Cisco CallManager Express

it looks like phones do not have ip addresses

sh ip dhcp bin

sh logg

sh ip dhc con


Thanks Tagir for your reply.

Sorry for the late reply. Didn't see your second post.

Used your commands but ephone command not available under telephony-service.

Ephone goes under global config not telephony-service. Try removing your load command and see if that helps. If you are not seeing any TFTP events then there is a communication issue between the phone and TFTP server. I would recommend posting the full running config if you want to get this problem resolved.

Removed load command

Strange about your communication issue between TFTP and phone as phone gets IP address and is pingable from router

Anyway. Attached is full running config

Thanks again Michael. Much appreciated :)

ip dhcp pool Voice_Scope
 must be     default-router


I also do foolprof config

I do add option 150 to data network to

Here are some changes I would suggest making:

!(removed .sbin on the alias)

tftp-server flash:CP7912060000SCCP050124A.sbin alias CP7912060000SCCP050124A

!(changed source address to your voice VLAN and specified load with new alias)

no ip source-address port 2000
 ip source-address port 2000
 load 7912 CP7912060000SCCP050124A

!(Recommend to specify this interface as the h323 gateway)

interface FastEthernet0/0.2
 h323-gateway voip interface
 h323-gateway voip bind srcaddr


Also make sure your files are available with tftp-server which looks like this for a different phone model:

tftp-server flash:apps42.9-2-1TH1-13.sbn
tftp-server flash:cnu42.9-2-1TH1-13.sbn
tftp-server flash:cvm42sccp.9-2-1TH1-13.sbn
tftp-server flash:dsp42.9-2-1TH1-13.sbn
tftp-server flash:jar42sccp.9-2-1TH1-13.sbn
tftp-server flash:SCCP42.9-2-1S.loads
