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
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
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
I know that persistance pays off but this is driving me crazy.
Can someone please advise
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:
Cisco CallManager Express

debug tftp events not work after configuring ephone with different tag
Thanks Tagir for your reply.
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.
ip dhcp pool Voice_Scope network 192.168.2.0 255.255.255.0 default-router 192.168.0.12
must be default-router 192.168.2.2
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 192.168.0.12 port 2000
ip source-address 192.168.2.2 port 2000
load 7912 CP7912060000SCCP050124A
!(Recommend to specify this interface as the h323 gateway)
h323-gateway voip interface
h323-gateway voip bind srcaddr 192.168.2.2
Also make sure your files are available with tftp-server which looks like this for a different phone model:
