<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> Im using SIP proxy with rtpproxy
behind a PIX firewall, I can use ATAs with NAT without problems to make and
receive calls, but when I use another type of telephone like grandstream I only
can make calls, the ports which I have open in my firewall are 5060
tcp/udp. I dont know if its because the rtpproxy/ser server cant be behind
a firewall or just need to open another ports of its just a bad
configuration.</FONT></DIV>
