Hi list, I have one E1 linK, PSTN, working very well, no sound problems. I was testing in laboratory some ATAs PAP2-NA from Linksys, at the same Asterisk's network, but I'm having one problem. 1. When I call another SIP phone everything goes very well and the quality of sound is perfect in both sides. 2. When I make an outbound call, by PSTN, with one of my softphones I have no problens too. 3. When we dial a number, through the digium card using the PAP2-NA, we can hear the other part with a high quality sound, but they listen to us very bad. It isn't an echo problem, the timbre of our voice becomes very different, poor. It's like a robot saying the words with a pause between the words. I have no load problem in my server. My telephones don't have any problem. They already be tested and substituted. I'm using g.711. I have bandwidth, it's local area. It's only happens with the PAP2-NA using the digium card. The card is working for another telephones.... My PAP2-NA version is 3.1.3. The leds are ok. my sip conf: [712] type=friend secret=*** callerid="My Linksys PAP2-NA p1" <712> host=dynamic canreinvite=no disallow=all allow=alaw allow=ulaw context=sip dtmfmode=rfc2833 So Anyone has the answer? Or can give me a help :-) Best Regards, Loureiro. -- Bruno de Assump??o Loureiro msn: loureiro_bruno@hotmail.com
