Re: PSTN loop not detected

phoenixlink · ‎04-07-2011

Have just configured a UC320 - single PSTN connection to FXO port #1 - PSTN loop not being detected - standard POTS handset works fine with PSTN line ~ so not PSTN line issue . What am I doing wrong ?

Hi Paul,

This might be a really silly question

Have you tried a different cable with it? The pin configuration might be incorrect for the UC to work with, it is rare to see this but it could be a problem.

Cheers,

David.
