First thing to check is if the phone is in headset mode, this is what it sounds like.
Check your "Feature Access Codes" form and look up the code to disable headset.
Hi sarond,
I think you're right. Any idea where I will find this form?
I found the manual online and it said to type 317 to turn off headset mode but as soon as I press the number 3, it comes up with INVALID on the screen. So I'm still not sure.
Also if you are familiar with the maintenance commands you could try "LOCATE FEATURE EXTENSION {EXT}" where {EXT} is your extension number.
It should tell you if it is headset mode.
After typing that command in, this is what I get:
IP Device ID: 15
Circuit Location : 1 3 1 15 1
Extension : 804
Active Features :
Headset
Phone Lock: UnLocked
MAC Address : 08:00:0F:45:D2:1E
Does that look like headset mode?
