[Asterisk-Users] Audio Quality over LAN very bad

[Chamberland-Larose, Guillaume]

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.

	Hi All,
	 
	I'm running Asterisk on the following
	 
	vendor_id       : GenuineIntel
	model name      : Celeron (Coppermine)
	cpu MHz         : 668.202
	cache 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 SIP which 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.
	 
	 
	Thanks and regards
	Nic
