Hi, all Suddenly I started to have bad sound quality. Happens with all providers as well as with softphones connected to my * server on the Internet. It was OK on 1.1.17, then I migrated to 1.2.5 and it was OK for some time. Nothing has changed in my setup, but voice quality degraged greatly. When I call someone, they can hear myself quite clear, but I hear lots of interruptions in the voice. It actually gets worse. It may start as a good clear conversation and in a few seconds it "slips" and I can not make out what they say. Seem to only happen when calling via Internet. I have tried to restart both * server and my main server/gateway. I also made sure no other traffic is going through. Nothing like P2P. When I do use P2P I am getting my usual dowload speed, so looks like my ISP is fine. I run ADSL 512/128. Any ideas on what could happen? Thanks, Rudolf

I think you are right. 1.0.7 I connect via VoIP providers -- via Internet only. No direct PSTN connection. (Well I do have TDM400, but did not have time to set ot up yet). I use Polycom SP300 phones I even have problems when talking to people with softphones registered on my * server. Somehoe, I am starting to suspect that my ISP have something to do with that. Is there any way to check quality of Internet connection? Not just speed but quality.
