Please help!! I'm trying to upgrade Cisco 7912G IP phone to SIP

leohopkins1 · ‎04-04-2014

Hello everyone,

I am trying my hardest to upgrade my Cisco 7912 to use SIP but I have hit a stumbling block.

I have set up the TFTP server and have these two files in the TFTP directory as per the instructions:

gkdefault.cfg

CP7912080000SIP060111A.sbin

I have specified the TFTP server on the handset and it connects okay, however it appears that the phone is looking for a lot more than just these two files and the upgrade does not happen.

The output of the log file from the TFTP server reads as follows:

Connection received from 192.168.0.5 on port 14914 [04/04 22:18:32.068]

Is anyone able to offer any help?

Many thanks in advance!

I have no idea where you got the idea that all you need are TWO (2) files and you can convert the phone to SIP. You will need the following:

DHCP option 150 pointing to your TFTP server;
The filename "OS79XX.txt";
The filename "XMLDefault.cnf.xml";
The filename "SIPMACaddress.cnf";
The filename "SIPDefault.cnf";
And finally, four firmware files for the specific phone model in question.

For more detailed instructions, go to www.voip-info.org and enter the statement "convert 7960 to sip" in the search field.

Hi Leo,

Many thanks I will have a look at this, the method I have was listed in a readme file downloaded from cisco's website itself. The contents of the readme file I have listed below.

Are you able to point me in the right direction of obtaining the correct files / firmware?

Many thanks !!

--------------------------------------------------------------------------------
ABOUT CISCO IP PHONES SOFTWARE UPGRADE IMAGES
--------------------------------------------------------------------------------

The Cisco 7905G SIP software package includes two upgrade images:

CP7905xxxx.zup
CP7905xxxx.sbin

The Cisco 7912G SIP software package includes one upgrade image:

CP7912xxxx.sbin

A Cisco 7905G IP phone may request either the .zup or .sbin upgrade image
depending whether it can perform image authentication, which is a
process all new Cisco IP phones use to verify the image authenticity.

A Cisco 7905G IP phone without the ability to perform image authentication
will request the .zup image first, which will provide it with the ability
to verify the authenticity of .sbin images in future upgrades.

A Cisco 7905G IP phone that can already perform file authentication will
only request .sbin files.

All Cisco 7912G IP phones are capable of performing image authentication
and will request only the .sbin upgrade image.

If a phone's profile specifies the .ZUP upgrade image, an authentication-aware
phone will modify the image extension name and request the .SBIN upgrade image
from the TFTP server.

--------------------------------------------------------------------------------
HOW TO UPGRADE A CISCO IP PHONE
--------------------------------------------------------------------------------

For your convenience, a default configuration file has been created to help
you quickly upgrade to the latest .zup or .sbin software image. The
"lddefault.cfg" for the 7905G and "gkdefault.cfg" for the 7912G are based
on the "lddefault.txt" and "gkdefault.txt", respectively. A default GUI/Web
password of "1234" is set. You will be prompted for this password when you
try to change the Network or SIP configuration, or access the phone's web page.
If the password is disabled (set to 0), then the phone configuration via the
web is also disabled.

To upgrade your Cisco IP phone, please follow the steps below.

1. Copy the following files to the TFTP server.

For Cisco 7905G For Cisco 7912G
--------------- ---------------
CP7905xxxx.zup CP7912xxxx.sbin
CP7905xxxx.sbin gkdefault.cfg
lddefault.cfg

2. Enable the use of TFTP on the Cisco IP phone.

3.2 Select Settings > Status > Firmware Versions
3.3 Check the software version

Firstly, Cisco will NEVER have a good documentation on how to convert 79XX phones from SCCP to SIP. This is because converting 79XX to SIP will take business AWAY from CUCM business unit.

Secondly, if you have a valid Service Contract, 7905 firmware can be found here and 7912 can be found here.

Go to the website I've mentioned in my previous post. That website is a wealth of information in regards to anything SIP with Cisco phones.

Let us know how you go.

hi. I have succesfully upgraded a 7912G phone to SIP image.

You will need 2 files , one is the sbin image as you pointed out; but the other is not the cfg as they say in the upgrade readme.

The other file should be called SEP[mac].cnf.xml, where [mac] is the phone mac address (uppercase), and this file should have the following content:

<device>
<loadInformation model="IP Phone 7912">CP7912010300SIP050414A</loadInformation>
</device>

where CP7912010300SIP050414A should match the name of the sbin file without extension.

Cheers,
