[asterisk-users] Background noise

[khalid touati]

Hi Guys,
i have recently connected my (working) asterisk 1.2 server, with two 1.4
asterisk servers (one using SIP the other using IAX), since then (i believe)
people starts complaining about a high background noise when using the
handset on Polycom phones (but when using the speaker it's fine, and i
noticed that my self), my question is, can anybody tell me any step to begin
diagnosing the issue, to be honest i don't know from where to begin!!
