Hi there, Having some issues with call quality when taking calls from E1, using Asterisk to reroute the call back out onto E1. Sometimes there's quite a big echo and others the line is just very scratchy. Call quality for incoming calls to VoIP is fine. To redirect the incoming call I use an AGI that fires off the Dial command to redial the extension back out over PSTN. Is this the right way to redirect a call out over PSTN? Would doing this cause any kind of call quality loss? Cheers for any suggestions or help, Ben Griffin Internet T: 0870 8040862 F: 0870 8040805 W: www.griffin.com <http://www.griffin.com/> -------------- next part -------------- An HTML attachment was scrubbed...

So far, I've found two possible solutions: a) Get a new motherboard b) Get a new motherboard and a new TE410p (instead of my current TE405p) I am still suffering this problem since I can't really afford to buy a new motherboard, cpu, memory.... besides, how do I know that after buying all that, it will even solve the problem? Looking forward to a motherboard whitelist.... ? someone? Regards, Adam
Hmm, When we first got our TE410p (we have 2 at the minute) it was in a normal IDE ATA100 box with a P4, and the static on the line was really, REALLY bad. We don't have this issue now we use a Compaq with SCSI, unless we reroute the call back onto PSTN. It doesn't always happen I might add though! It seems to be some landlines that have more problems than others. Mobiles tend to be fine. Is this a Digital -> Analogue issue? Strange that it should be fine the rest of the time :( Yes, a hardware guide for Asterisk would be a god send! I'm getting two new DELLs next week to play with (SCSI again). I'll let you know how well they work with Asterisk!
