Yealink T48g lost registration after restart 3cx

[jan-syntell]

Hello everybody,
I bought Yealink T48g withone dont have Provisioning Template, so I must configure it manually.
It's works well, but after restart 3CX [for now, trial version] it cannot register properly.
When I change settings sometimes it work, sometimes not...
Did someone had the same problem? It is possible a server send some unregister-order to this new featured phone?
I will be glad for each advice.

The T46G template works perfect for the T48.

Here is a link to the updated template for the T46 in 3CX which now populates T48 in the dropdown.

Any idea when the T48g will be officially supported by 3CX? About to purchase 3CX and 20+ phones and was looking to use the T48g

thanks,

My guess is simply they are behind in the development schedule and its low on the priority list under things like the web meeting, high availability, mac client, etc

T48 works well dont hesitate.

I also recomended upgrade firmware for this T48G - after it it start working more stable for me.

I also recomended upgrade firmware for this T48G - after it it start working more stable for me.

Which firmware version to you recommend for the T48G?

My phones came with 35.72.0.6 (not listed on Yealink web site).

Yealink website has 35.72.0.5 & 35.72.0.10

Interestingly enough if I register the phone with 3CX and choose "Firmware Upgrade" it will offer me 35.72.0.225 (also not on the Yealink website).

I found that the newer firmware seems to work well.

One thing I find though is that if I do a factory reset on a device with the higher firmwares (35.72.0.225 & 35.72.0.10) and then re-register it, it won't let me upload a new background image to the phone. I have to downgrade the firmware to 35.72.0.5 and then upload the background image and then upgrade the firmware and all is fine. Afterwards I can even upload new backgrounds to the phone. All stays fine unless I have to factory wipe it in which case I have to repeat the downgrade-upgrade procedure.
