HFL unit while making an outgoing call the person on the other end cannot hear anything i say just a static noise. but i can listen to the person on the other end..But on the other hand incoming calls are fine. Is there a problem with my HFL ? Landline at home dials in HFL without a problem. but if i call my land line or any cell i can hear the ringer and voice on the other end but they cant hear me. all they hear is a static.. Any recommendations or solutions.
