[asterisk-users] Upgrade cisco SIP phone 7940

[Kelvin Williams]

Be sure your OS79XX.TXT and SIPDefault.cnf file and SIP[MACADDRESS].cnf file
all agree on the version of software the phones are to be running.

 

For example OS79XX.TXT should read: P0S3-08-2-00, and in SIPDefault.cnf a
line should read: image_version:P0S3-08-2-00. If you were trying to run
P003-08-2-00

 

The image_version line is not required in SIP[MACADDRESS].cnf file so I
wouldn't put it there otherwise if you have many phones you'll have to edit
each phone each time you change the software.

Subject: [asterisk-users] Upgrade cisco SIP phone 7940

 

Hi All,

 

My current 7940 phones use P0S3-06-3-00.  I'd like to upgrade them so
they're not massively out of date.

I found a page at http://www.voip-info.org/wiki-Asterisk+phone+cisco+79xx
that gives some info, and using the cisco links there have tried to upgrade.

 

According to the procedures, I should be able to upgrade, but once the
phones loaded and reboots it says it downgrades again and reboots, then the
cycle starts again.

 

Anyone had any success in doing this?
