asterisk users - Jun 2006 - Analog Line "Static" and Low Volume

Have a customer running a 3rd party PBX implementation based on Asterisk,
not utilizing SIP inbound and outbound calls I believe are coming through a
Digium TDM2402B.  They are utilizing Polycom phones.  They are experiencing
frequent static on the line, and overall insufficient volume on
conversations.

 

They are in a bit of a rural area, I was curious if anyone thinks it could
be an issue with their POTS provider, or if it is PBX related?  Would adding
echo cancellation perhaps alleviate static on the line, I did not think it
would, just looking for some feedback.  They have tweaked the gain settings
and this has not produced any meaningful improvements.

Definitely sounds like it could be a PSTN issue.  I also have seen both 
those circumstances (static and low volume) with one of my ata's 
(AG168V) which was rectified by a firmware update...

PS I don't think an Echo can. will help those issues at all.
