I have a asterisk server. Two SIP Soft XLites are connected to the server. I am able to make
calls from one SIP Phones to the other SIP Phones and landlines successfully. The SIP Soft Phone on th eother side can hear my voice but I cannot hear their voice.

They can call my local cell phone as well. Samething, they can hears my voice, I cannot hear their voice.

The microphone and speakers are working on both sides because we are able to use google talk and are able to talk successfully. But it would not work on XLite over asterisk for some reason.

The Asterisk server is a linux server. There is no firewall between the servers. It is in a DMZ.

Any suggestion how to get it to work Smile

Thanks,
Sanjoy.

My bet is that it's not a *true* DMZ. You're still dealing with NAT,
and that's what's causing the one-way audio.

This topic has been discussed ad nauseam on the list and is documented
quite well on the wiki - search there and you'll most likely find the
answers you're looking for.

Erik, i having the exact same problem, but couldn't find anything on the
wiki for that. Maybe you could assist and point us newbies to the
relevant page.

Is there a mailing list archive search engine somewhere?

thanks

Look at the "transmit silence" option in X-Lite and make sure that the
client *does* transmit silence, not attempt to keep quiet. I can't
remember if checking the box transmits or does not transmit: you want
it to transmit silence.
