If ...."No audio can be heard from either the entire phone or specific parts like headset or speaker."

=== Firewall conflict ===

If the headset mode has been activated, the audio problems maybe the result of a firewall conflict. Contact your system administrator to see if the audio issue is the result of a firewall conflict. If so, they can resolve it.

=== Headset mode is off ===

If the audio
problem most likely liesis localized to the headset it maybe because the headset mode is off. Headset mode can be turned on by placing the phone in the cradle and dialing 315 (Headset on feature code) or 317 (headset on/off feature code). If Headset was off either should work and the display should show HEADSET MODE ON.

=== Bad headset receiver ===

If the audio through just the headset is faulty and its not due to a firewall conflict or the mode is off the headset receiver may need to be replaced.

=== Bad Internal Speaker ===

If the audio problem is not the result of firmware conflict and is localized to just speaker mode this may indicate a faulty internal speaker that would need to get replaced.

=== Bad Logic board ===

If audio problem is not the result of firmware conflict but persists in all parts of the phone you may have a faulty
logic board.

== Unresponsive/ Sticky buttons ==

=== Bad button pad ===

This will generally require that you tear-down the phone and either clean the connections between the buttons and the logic board or replace the button pad altogether.
