asterisk users - Jul 2006 - Voice with echo

Hi group

I have my * box installed with a public IP address and I'm testing two
extensions. I'm using SJphone for softphone. When I make the call from an
extension to another, the voice sounds with echo. Besides sounds like creepy
and it seems like a radio (for making a description)

This is my sip.conf :

And these are my extensions:

;***************** extension de usuario 1 ******************
exten => 2426098,1,dial(SIP/usuario1)
 exten => usuario1,1,goto(2426098,1) ; To be able to dial with text,
"usuario1"


;***************** extension de usuario 2 ******************
exten => 2418150,1,dial(SIP/usuario2)
 exten => usuario2,1,goto(2418150,1) ; To be able to dial with text,
"usuario2"

This is an output for the conversation: ********************

I don't know if there is some problem with the codecs or on my
configuration. Do I have to change some line?

Thanks for any help.

Are you using a headset?  If not you are probably just hearing the  
speakers feedback through the mic.

Your configurations don't look like they are the problem to me.
