Whoo Hoo! I managed to get * up and running last night. My most pressing problem is that there is a considerable amount of hiss heard by the called party when using a SIP phone (xten or GXP-2000). I've tried two different computers with two different headsets, and the hiss still remains when you should be hearing silence (or near silence). The hiss does not occur when you're on one of the extensions of the legacy PBX (Nortel). Anyone have some ideas on where I should be looking? Basics below: PSTN (via PRI) --> * --> PRI --> Nortel Meridian I've got a basic dial plan setup to forward most calls through * to the legacy PBX.

So far all of them have high frequency hiss and noise. I record and then apply a low pass filter and the playback sounds fine. When I have the time I will be testing some usb headsets. I get the hiss and noise with softphones using all headsets I have tried so far. I don't get it with grandstream budgetone 101 phones or phones connected to ata's.
Is the ambient noise in the room high?> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users- > bounces@lists.digium.com] On Behalf Of Matt Riddell > Sent: Tuesday, November 08, 2005 8:53 AM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: Re: [Asterisk-Users] Hiss > > Paul wrote: > > I get the hiss and noise with softphones using all headsets I havetried> > so far.
