server that is behind a cisco pix firewall. I have opened up ports udp / tcp
5060 and rtp 10000 - 20000 ports. <br><br>When I make a phone call out through
the sip provider, I can not hear the other person, but the other person can hear
me. Do I need to setup a stun entry for the asterisk server since it is behind
the firewall? <br><br>How can I fix this issue? <br><br>Thanks
