[cisco-voip] CCME problem using 7921G Wireless phone

[Robert Bell]

Greetings Everyone,

 

I'm hoping someone can help me out here.  I am trying to setup a Cisco 2851,
running a 12.4 IPAdvServices IOS with a Cisco wireless 7921G phone and I'm
having a little trouble.

 

I've got the phone working with the wireless network (not Cisco, but it
functions w/ 7920 and network wise 7921G phones).  I've pulled an IP Address
from the router, it loads all the TFTP info, etc to the 7921G.  My problem
is I can't load the firmware.  I've had a few problems, first was I didn't
have a XMLDefault.cnf.xml file.  I'm not real familiar with this file or
XML, but I found a sample file, loaded it on the flash and set it up for
TFTP.  I'm not sure if I need to modify it or not though or how.

 

Anyways, the phone seems happy with the file I found so I started to try and
configure the phone.  Just a little more background, I loaded the
CME-basic-4.2.0.1.tar file (I'm writing this from memory I may have the
version numbers wrong there), and using the "archive /xtract" command I also
loaded the CP7921-1.0.3.tar file.  So I think I should be good updating the
CCME files to the 4.2 version which does support the phone; however, when I
go to the telephony-service config and try and issue a "load 7921
CP7921-1.0.3" command it doesn't work because there is no 7921 option.  

 

Also, when doing a "Show telephony-service" command it shows the version is
3.3 (which I think is the CCME version).  So if loading those new IOS and
the CME-Basic file doesn't upgrade the CCME to the higher version then what
am I not doing  Cisco doesn't have a lot of info because I think they want
you to use CCM and just have CCME for local survivability.  

 

Also, I know this isn't right, but I thought I'd give it a try.  Since I
don't run any 7902 IP phones, I used this command in the telephony-services
configuration: "load 7902 CP7921-1.0.3" and in the ephone config specified
the type as a 7902 trying to 'work around' the issue.  The phone does now
try and load the firmware, but the phone continues to try and register
downloads the CCM info, attempts to load the firmware and gives messages
like: "Not in Service" and "firmware update failed."  In the Status message
section on the phone itself it keeps logging the SEP<MACaddress>.cnf.xml
file every two minutes or so.  No errors though.  

 

I'm really at a loss here.  I know I probably am not doing things the
'right/cisco way' but I've followed all the information I can find online.
There's not much information though for troubleshooting and what is out
there isn't working the way I think it's suppose to.  Any
ideas/suggestions/help would be greatly appreciated.  I think if I can
update the actual system to show version 4.X it may work since version 3.3
and earlier doesn't support the phone.
