in the rtp.conf you specify range of ports, this range should be forwarded on the firewall to the asterisk box.
I have asterisk running on 192.168.0.250 ip and connect to broadvoice server. here is my iptables rule: -A PREROUTING -i eth0 -s 147.135.0.128 -p udp -m udp --dport 10010:10013 -j DNAT --to-destination 192.168.0.250 with rtp range being: rtpstart=10010 rtpend=10013 -- Alex.
