asterisk users - Jul 2005 - network problem -- echo

Hi, all

I have problem with echo.
I am running Asterisk server and someone else is running FireFly IAX2 phone. 
When I talk to this person I get very strong echo on my end. His end is OK.

At same time, I was trying to set up someone else with exactly same setup 
and there is no problem at all. So, looks like this is a network problem at 
this particular site. He is on ADSL 256/64. I have feeling that it is his 
router, but this is just a gut feel. I do not have other ADSLmodem /router.

Are there any way to troubleshoot echo problems?

Thanks,
Rudolf

1. Ask if they are using a speaker and mic built into the PC (This will 
create echo) - solution: Tell them to use a headset

2. Check if they have any output volume (in volume control, advanced, 
recording) set to record.

3. Check if they have a crappy sound card - solution: get another sound 
card/usb headset/usb phone

Start with the simple things.  Can he use a different PC there?

The problem is not their PC. I am getting effect as if I am talking to 
myself over the phone. Very loud and clear. Not the echo effect you get 
because they use speakers.
