asterisk users - Mar 2007 - Newbie Question

Hi all,
  I'm new to Astrisk so bear with me.
  I have just installed AsteriskNOW and am quite familiar with RH
Linux. I have configured it and am using Xlite to connect and learn to
move around the conf files. I have a problem, however. The client
connects and dials ok, but there is no audio. In searching the
archives I found discussion of this issue primarily centered on NAT
issues. This is not my issue (I think). Here is some info:

1. * server and clients are all on the same subnet but are separated
from the internet by a proxy/firewall which forces all port 80 traffic
through the proxy.
2. The server has a single channel fxo card.
3. Snip of sip.conf:

[test]
type=friend
secret=verysecret
regexten=1234                   ; When they register, create extension 1234
callerid="Test Unit" <1234>
host=dynamic                    ; This device needs to register
nat=yes                         ; X-Lite is behind a NAT router
canreinvite=no                  ; Typically set to NO if behind NAT
disallow=all
allow=gsm                       ; GSM consumes far less bandwidth than ulaw
;allow=ulaw
;allow=alaw
mailbox=1234@default            ; Subscribe to status of multiple mailboxes
context=internal


Here is the problem:

Xlite registers fine. When I dial 500 to access the demo, the *
console shows the client connect and the demo audio plays. However,
there is no sound on the client end. I have installed Xlite on an XP
workstation and on a *nix workstation. Both installs behave the same.

Any thoughts? Or do I need to post more details?

Thanks,
Chris

If both the asterisk server and the softphone are on the same LAN then I 
would look at your firewall settings on the box. Make sure you have 5060 and 
10,000 - 20,000 UDP open. If the phone is connecting to the server over the 
internet and the server IS behind NAT then you need to forward ports 5060 
and 10,000-20,000 UDP to the asterisk server.

I use it on Linux and it does.
