One way audio on 7920 ?

| I am playing around with a 7920 and so far I seem to have it working but I
am only getting one way audio. I find this to be odd as it found the
callmanager server, updated the firmware, registered and I am able to place
calls to and from it but no one can every hear me. I can hear them just
fine but they cannot hear me. Same issue when calling Unity and leaving a
message. The message is empty.
Any ideas on where I should even begin on resolving this?

| Check to make sure that your 7920 and your 1200 AP are putting out the same
power.
Common mistake may be that one is putting out more power than the other, and
the other does not have enough power to reciprocate the signal.
Newer 7920 firmware (post 2.0) use DTPC (Dynamic Transmit Power Control) to
ensure this is not a problem.
Also if it is an older phone, it could be a manf defect:

| press the base of the 7920 phone together firmly. there is a field
notice on loose screws in the base of the phone causing the Mic to
appear broken.
