I have a trixbox server and every works find except the external SIPs. Inside net all sound goes fine, but if I use a SIP phone outside the net, I can connect, I can receive calls but I there is no sound.

I have this text in the sip_nat.conf:

nat=yes
externhost=xxxxx.dyndns.org
localnet=192.168.1.0/255.255.255.0
localhost=192.168.1.210
externrefresh=10
qualify=yes

And I have the ports from 5036 to 5082, 4569 and from 10000 to 20000 redirected to 192.168.1.210 on TCP and UDP.

What's wrong?

Thank you very much in advance
