[Asterisk-Users] SoftPhone to SoftPhone with No Voice

[deepak at netandroid.com]

Hello

I Installed Asterisk on RedHat 9. I am currently try to configure minimum with
two softphone talking to each other over the LAN. I am using X-Lite softphones
from xten.com site. I defined 3 phones in sip.conf and also specifies in
extensions.conf file. I am able to ring other computer but there is no voice
exchange ( i can't hear any think except ring). Here is the portion of sip.conf
and extensions.conf. 

Let me know if i missed something.

Thanks

Deepak
