PROBLEM:
-when call to other extension, no tone when press any key
-when receive call from other extension, no ringing but light blinking
-I can hear other party voice and vice versa
-I can see there is voice mail indicator blinking, but I try to access it ask me an account. I can't hear anything.
-Speaker phone, no sound as well

Seems this problem is common for Yealink.
How to fix that

thanks

hi

please check if you set the volume to the mute

then try to factory reset the phone and test again

Volume max
Factory reset already try 2 times
No DND.

I'll return this item to the seller this morning.
I'll try http://www.escene.cn because it has
-LDAP Phonebook
-https GUI
Does Yealink have those?
