Asterisk on our LAN with Cisco IP phones and softphone clients, SJPhone and
Firefly. Everything on our LAN works fine and the quality is good.
We have recently registered other callers not on our LAN who are using SJPhone
and Firefly as well. The audio quality is fine, but I consistently hear a
buzzing sound in the background. We have experimented with the line in and
microphone volume settings. Turning it down helped some, however the
background buzzing is still there. I've experimented with both softphone
clients, different codecs and protocols (SIP and IAX2). The buzzing does
go away when he mutes his SJPhone client. I'm thinking it might be a bad
sound card or a bad headset connections. Any advice would be
appreciated.</FONT></SPAN></DIV>
