[Asterisk-Users] MarkK: Qualty Problems

[Mark Kidd]

Hi all

i am having odd problems.
nothing worng with the server starting up or anyhting like that.

asterisk server = P4 2.4 512M Ram 80gig/hd 100M/Lan Digium 4 port FXO Card
i am using X-Lite on macines on the same network all running on 100M/Lan

calling etc all works fine calling to PSTN works fine.

the problems come in with actualy quality

calls between people on the same network are not incredibly clear often
small lag and on some calls
the people can hear their own voices after they have spoken. +/- 1 to 2
seconds later.

i have tried multiple codecs but no change. almost like a slight scratch on
the line.

we are all using Headsets. (good quality headsets).

calling externaly to PSTN numbers gives the same results.

usable but no where near as clear as an ordinary phone would be.

any ideas greatly appreciated
