I am installing secure 9620L PDB SIP phones and the handset has no audio. The speaker works fine but the microphone is disabled on purpose. Is there a special power requirement? If I plug in a regular 9620L phone it works fine. Any thoughts?

An update. There is a "push to talk button" that is actually labelled HOLD on these phones. It is not a hold button so I guess I will just peel off the sticker that they placed on it.
