Full Version: Lync Firmware T-48G
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
Just purchased a few Yealink phones for testing with MS Lync 2013. I would like to obtain the Lync Firmware so I can begin my testing. We need to deploy a few hundred student phones and these will work. I need firmware for the T-48G and the T22.

Thanks in advance.
Dear,

To test Lync firmware, you will need to import a license. Please send an request email with the MAC address of your device to support@yealink.com or support.usa@yealink.com. Our engineer will reply with you the firmware and license the soonest.

Hi,

where I can get the firmware for T22P compatible with Lync?
Hi,

You can download the Lync firmware from the link below.
And the 7.7.0.56.rom is Lync firmware for T22, the T48-35.7.0.56.rom is the Lync firmware for T48G.
You need to upgrade to Lync firmware and reset the phone after upgrading.
And you need a license to make the phone work normally.
You can fill the register form and send it to us, we will apply the license for you. And the license is free.

Hi,

we also want to use the T48G with Lync but can't find the Firmware. Your FTP files don't exist anymore.
Could you please help me?

Thanks.
