Yealink Forums

Hello,

I'm new to Yealink, and I'm troubleshooting an issue with Skype for Business online related to calls dropping while using T48G and T46G phones.

While troubleshooting I noted the version of the firmware on the T48G is 35.8.0.60. Per the Microsoft site the tested firmware version listed is 35.8.1.52: Yealink T48G Skype for Business Edition website

I cannot find any reference to a version 35.8.1.52 on Yealink's site. Is this a typo, and is the correct version 35.81.0.25? Is 35.81.0.25 the version tested and certified to support Skype for Business Online?

Thank you,

Jeff

Hi Jeff,

All T4XG series support SFB online and on premise.
Now, just T48G and T46G get certificate, for other phone types, we are getting certificate now, if everything goes well. They will get certificate in May.
About the 35.8.1.52 version, it is which we sent it to Microsoft for test.
In our website, the 0.70 version is base on this version to develop and fix some bugs.

Regards
Lucia
