Testing AVAYA 9620/9630/9640 SIP phones in connection with other SIP PBX systems like Mitel MX-ONE?

It seems that the upgrade stops. I would like to upgrade the 96xx phones from H.323 to SIP, but has not yet had the luck with this.
Would it be an option to use the alternate text-ini file, listed below:

What's in your DHCP string?

Put SIG=2 in there to make the phone pull SIP firmware.


Default is 0 - stick with what you are
1=h323, 2=sip.

Also, read these release notes:

Seems you have to go through h323 release 3.

"Deskphone SIP 2.6 can only be loaded onto a 9620C or 9620L running H.323 firmware if either
 The 9620C or 9620L is running Deskphones H.323 3.0 or later
or
 96x0Hupgrade.txt includes hb96xxua3_00.bin

Thank you - we will try this asap...

Hi again

We have tried to upgrade the 9620 to SIP using the xx upgrade file that is loaded well into the phone. But in the display it reads that the callserver cannot be found and when we try to edit the setiings, this is not possible. It is only possble to restart the phone, and the the same procedure can be done - i.e. not possible to change the settings - only restart is possible.

You should be able to edit the settings - but even at that, it is very long to do by hand from the dial pad.

Your DHCP string should have HTTPSRVR=x.x.x.x and the phone should be asking for 46xxsettings.txt from that http server and it is where you would define any other parameters related to getting the phone connected to your SIP system.
