[asterisk-users] SJphone behind NAT/Firewall without sound

[Amit Nagpal]

Hi,

I re-created your setup locally - even ran your script to setup NAT

192.168.12.2 (SJPhone) <----> 192.168.12.1 (NAT-1) 
                                           |
 -------------(nat box)--------------------
|
(NAT-1) 10.0.15.101  <---> 10.0.15.102 Asterisk

And another client (Xlite) behind a separate NAT.

I made a call from SJPhone to XLite and vice versa - I am getting
Audio in both directions.

I used SJPhone 1.65 on Windows, and Asterisk 1.4.17.

Your problem lies somewhere else. Your script looks just fine.

Regards,
Amit.

No. I dont manage the asterisk server.  I just manage my
proxy/firewall, and i need to my users can connect to that server.
The asterisk server is of another company.  But the laptop users can
connect without problem to that server, from any place, except from my
LAN.

This is my scenarie:

LAN-----FW/PROXY------INTERNET--------ASTERISK-SRV

thanks in advance
