I have discovered a problem I've never seen before.

On a 6 PIM 2000 IPS, when you use an analogue extension for a voice call (using a standard analogue phone), the call quality for the user at the analogue phone end is both exceptionally quiet (including dial tone) and also has lots of static with speech.

The caller - whether on a digital, IP or external connection doesn't hear any issue with the call - sounds fine and loud and clear.

It happens on any analogue card in any PIM. To me it almost 'feels' like a physical problem and not a programming one. I've never encountered this before (in 10 years supporting IPS).

Any ideas?
