It was also my first though, but my LAN is very SIMPLE, so I was 
wondering if something else could cause the problem.

You're probably right, but it depends on Asterisk internals (which I 
don't know well).
If Asterisk would stop to send RTP audio when just a qualify packet get 
lost it can make the situation worst.

It should, but my LAN is very simple...
I have a 10/100 Mbit switch with no more than 15 servers on it.

Traffic on the LAN is not heavy even if the time of the day I see in the 
logs make me think it could be an issue related to network load trafic

Anyhow I'll try to generate some heavy traffic on the LAN to see if it 
could be related to that.

I also noticed that this problem began to happen when I upgraded my 
Asterisk to 1.2, but it can be a concidence.

Do you think it could be related to bugs in ethernet drivers, kernel or 
whatever at the OS level ??

We have some Asterisk spread all over the public Internet, but firstly 
we should solve this problem at a LAN level

Tnx for attention
