[Asterisk-Users] Audio Quality over LAN very bad
Hi All, I'm running Asterisk on the following vendor_id : GenuineIntelmodel name : Celeron (Coppermine)cpu MHz : 668.202cache size : 128 KB with 192 MB Ram Audio coming from Asterisk (the demo ) is excellent when using a SIP phone on the LAN to Asterisk, and when dialling in from outside via ISDN to Asterisk. However, when connecting from SIP phone to SIP phone (across LAN) and dialling from externally to SIPwhich is on the local LAN it is very choppy and one can barely make out the other party. I'm using an Eicon Diva 2-m card and 100mb network all round. What could be the cause as I believe bandwidth is ruled out.

Maybe you're transcoding on the server with cpu intensive codecs? That would be the first thing I'd look at. Try using G.711 (ulaw)on both SIP phones and remove reinvite=no and canreinvite=no from your phone declarations in sip.conf. Hope that helps.

Thanks for the reply, It was on GSM, Ive changed to ulaw last night, It did make a differance but I'd say its still not as good in quality as the recorded messages being played back. What is the suggested or should I say, "Best Practise" when it comes to audio codecs used on asterisk ?

You should check also if your linux is using swap (cmd free) Probably it will becouse of 192M RAM than the speed of harddisk Is in question too -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chamberland-Larose, Guillaume Sent: Tuesday, February 01, 2005 2:07 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] Audio Quality over LAN very bad Maybe you're transcoding on the server with cpu intensive codecs?
