Downgrade 9608?

Downgrade 9608?

Downgrade 9608?

Hey folks
I have a customer running rel. 8.1 and adding a new 9608 phone is giving me a headache.

Works perfect to install and use but after a reboot it appeared as model 4624 (or something like that) in system status. Still able to make calls but was quite dumb.

I read here: https://downloads.avaya.com/css/P8/documents/10101...

"Attempts to downgrade these models to lower versions of software will be
rejected. If these models are implemented in an environment that uses lower versions of
software for other 9608/9611G/9621G/9641G IP Deskphones, it is recommended to use a
mechanism to differentiate the software loads such as different HTTP servers or different

This particular phone has rel 6.6401 and does not retrieve the older files on the sd-card.

Some guidance would be awesome! An upgrade of the pbx is in the plans but not in the nearest future.


RE: Downgrade 9608?

That readme file is for Aura, not IP Office. You're basically screwed, the phone will not downgrade, you must upgrade the control unit.

RE: Downgrade 9608?

Thanks for the answer (even though I didn't like it) :D

RE: Downgrade 9608?

I had an issue where 9608s would suddenly show as 4624 in System Status, it seems to be fixed in later releases.
Although this was on 9.1.something.

Are the phones on the same subnet as the IP Office?

RE: Downgrade 9608?

Yes IPO LAN2 and all phones are on their own subnet (VLAN 20)

I've also seen wrong devicetype with a 1608L at another customer. Just threw in another shelf-warmer 1608 I had and never thought about it until now.

RE: Downgrade 9608?

I mostly had this problem on remote phone who got this after reconnecting from network loss.

RE: Downgrade 9608?

What version of 8.1 ?

RE: Downgrade 9608?

It's running 8.1(43)
Are you suggesting upgrading?

RE: Downgrade 9608?

upgrade to 8.1(95)

RE: Downgrade 9608?

Known issues, upgrade

RE: Downgrade 9608?

You probably have the new 9608 which have there own lowest versions of software and these are not supported on 8.1
Upgrade the IPO and it will be fixed.


I'm not insane, my mother had me tested!
