Level 1

Dear Experts,

I have CME router 2811 with 15 - 6921 phones and added 1 new Cisco 7962 phone. All the 6921 phones are registered and working fine.

7962 phone does not register and the screen goes blank after the phone boot. Software version the phone is running is 9.3.1 SR2-1S
Verified the CNF File is created

tftp-server system:/its/vrf1/XMLDefault7962.cnf.xml alias SEP501CBFFC8735.cnf.xml

 

Here is the configuration on the router.


ip dhcp pool VOICE
   network 192.168.10.0 255.255.255.0
   default-router 192.168.10.1
   option 150 ip 192.168.10.1

 

ephone-dn  11  octo-line
 number 2211
 label ABC 2221
 name ABC

ephone  11
 device-security-mode none
 mac-address 501C.BFFC.8735
 type 7962
 button  1:11

The results of the debug tftp events are as below -

What version was the 7962G initially running before?  If it is 8.3(3) and earlier, you need to do an INITIAL upgrade to 8.5(2) before jumping to 9.3(1)SR2.  

SCCP Firmware Upgrade Issues

 

 

Leo,

I haven't upgraded the firmware. That's the default  firmware since I connected the phone. Shall I update the firmware to a higher version? Could this be a firmware issue.
 

The CM Server settings in IP Phone display "CM1 unavailable" though of the CME IP is correct.

Also I have upgraded the firmware to cmterm-7942_7962-sccp.9-3-1SR3-1 from SR2.

 

 

Please post your full config

Thanks for your response Sean. Please find the attached config.

 

 

 

Hi,

 

So the phone actually upgrades correctly and pulls down the software, but then fails to register? What IOS are you currently running?

Yes... the IOS is

(C2800NM-ADVENTERPRISEK9-M), Version 15.1(1)T

 

This could be a compatibility issue. Looking at the feature matrix, 15.1 is CME8.8 and only has support for SCCP42.9-2-1S.loads. Even the latest CME (10.5) only has listed support for 9.2.1 on 7962.

 

I would try downgrading the phone firmware to 9.2.1 and see if you continue to have the issue.

 

Also, make sure you are advertising all the following files on TFTP:

 

  • SCCP42.9-2-1S.loads
  • apps42.9-2-1TH1-13.sbn
  • cnu42.9-2-1TH1-13.sbn
  • cvm42sccp.9-2-1TH1-13.sbn
  • dsp42.9-2-1TH1-13.sbn
  • jar42sccp.9-2-1TH1-13.sbn
  • term42.default.loads
  • term62.default.loads

thanks Sean.. will try to downgrade the phones to old firmware tomorrow and update with the results. thanks.
