Hello Nick,
Sounds like you've been in the wars!
Aye!
gradually over the course of a few minutes, the Lag from one side of the conversation increases all the way up to nearly 10Seconds!,
We've never seen this happen with asterisk, however there are a few posts on the BB's regarding GSM over internet. Try running your tests with SAIL set to fidelity mode.
Is already set to fidelity mode.
On the face of it, it looks like a resource problem somewhere. We have a few questions....
You say "one side of the conversation", do you mean one particular party is lagging but the other is OK? Please clarify.
Correct. One Side is pretty much OK, the other goes Laggy and horrible
Are these lan-to-lan calls or is one party coming in over the internet?
LAN-LAN on apretty decent Switch, One of the Machines is on Wireless and I can check tonight if that is a problem, but I've not had issues with anything in the past..
If so, what bandwidth do you have and what codec are you using? What is your cpu usage during the lag phase? How much memory do you have on the box and what cpu speed?
Asterisk Box is a P4 1.7Ghz 384MiB DDR Machine.. All good quality components (Intel branded Mobo, Branded memory etc.)
According to top, the cpu barely wakes up during the calls.
I've been running TCPDump and I can see the UDP4569 Packets hitting the asterisk server, but it doesn't seem to respond at all.
Have a look at what's happening by running ipchan on the asterisk box. It will show you the packets that your machine is seeing in realtime. If you have a traditional router, try removing the server-gateway machine from the scenario and use your router to forward the 4569 packets directly to your server-only machine. To check whether 4569 is open run either...
netstat -anp | grep 4569
or
lsof -i | grep 4569
These will tell you the port state and the PID of the application that opened it.
Let us know how you get on.

[/quote]The router is a traditional No-NAT variety (Not 'standard' ADSL modem/router PAT stuff) and its not blocking anything, but i can set up a psudo-DMZ and connect over an ethernet connection to the outside IF of aquarius to test if it a problem...
I'll try your tests and get back to you this evening. Thanks for the support guys!
