Hi Cisco techs,
7912 IP phone fails to register in CME 3.3.
CME shows name of user, MAC address, phone sequence number, telephone number and the type being normal but doesn't register when doing command
sh ephone registered
Replies with no ephone in specified type/condition
Sh ephone output is
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:0
IP:0.0.0.0 0 Unknown 0 keepalive 0 max_line 0
Sh telephony-service output is
cme_router#sh telephony-service
CONFIG (Version=3.3)

I can ping the phone from the router no troubles
And the router clock keeps going back to 19:43:41.519 14:54 Fri Mar 1 2002
Please advise further. Thanks again. Let me know if more information is required

Why would you use 192.168.3.0 as the source-address/TFTP server? They need to point to the CME box.

Your ip source-address doesn't look right:
ip source-address 192.168.3.0 port 2000
What does "show ip int brief | e una" show for addresses on the box?
Try running "debug ephone register" as well to see if you get any useful information.
Also what TFTP server address do you have configured on the 7912?

Thanks Brian. I will run these and let you know
04-29-2014 05:44 PM
OK. IP source-address is correct.
cme_router#sh ip int brief | e una
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 192.168.0.12 YES NVRAM up up
FastEthernet0/0.1 192.168.1.2 YES NVRAM up up
FastEthernet0/0.2 192.168.3.2 YES NVRAM up up
Debug ephone register output
cme_router#debug ephone register
EPHONE registration debugging is enabled
cme_router#
TFTP server address is 192.168.3.0.
Phones IP address is 192.168.3.1
Let me know if more information is required. Thanks Brian in advance

Why do you have the source address and TFTP server set to 192.168.3.0 when that's not an IP address on the box?
Change the ip source-address to 192.168.3.2 and change the TFTP server to 192.168.3.2 as well.

Thanks for your reply Brian.
Source address is the DHCP server that the phone is getting the IP address from as the phone confirms.
Same as the TFTP server.

I understood that the TFTP server could either be the CME box or separately.
OK then. Will re-configure. As I have also found out. The files for the phone appear to have gone missing as when I used sh ephone phone-load..the output is nothing. As in nothing.
