Dear Support,
We have 1x MyPBX U500 + 100x T42G + 30x T46G in our university. We just finished installation of IP phones on users desk and started to remove old analog phones.
And then nightmare started...
It is already second week that every day I receive complains from number of IP phone users stating that their phones are accidentally went reboot during calls.
I noticed that all affected persons are T46G model owners (though it could be just coincidence).
Please advice what could be the reason of Yealink IP phones reboot, and how to eliminate this issue ?
Thank you
