That's funny, I'm trying to chase down pop/clicks on two of my installations
but they are only heard by the internal recipient. The outside caller
doesn't hear it at all! We have Dell SC420, Asterisk/Zaptel 1.2.1 and a
TE110P integrated into a legacy PBX.

It only occurs with internal users that are using their legacy handsets to
call out through Asterisk. The Cisco 79XX users do not have this issue.
