Kristan Posted August 18, 2009 Report Share Posted August 18, 2009 Hi all, Not really a PBXnSIP question, but I was hoping someone here might have some tips. I have a PBX customer who has moved to Ireland, and can only get satellite broadband. We've got a phone up and running, but the quality is "iffy" to say the least. There's echo, delay and starting the conversation means waiting 10 seconds or so before the audio sorts itself out (I guess as the phone/PBX figure out the latency and jitter). Is there anything that can be done either at the PBX side or at the phone side (linksys SPA-942)? I was thinking of trying something other than G711 also maybe? Anu suggestions would be appreciated! Thanks, Kristan Quote Link to comment Share on other sites More sharing options...

You should not use G.711 in this case. Maybe GSM or G.726 or G.729. And you should make the packet length like 40 ms or even 60 or 80 ms (the delay does not matter anyway). Then you can get the bandwidth down from 80 kbit/s to something like maybe 15 kbit/s. Quote Link to comment Share on other sites More sharing options...
