sounds like the inbound (out from the phone, into the local net) RTP packets are getting dropped..

just a guess here.. whats the output of "iptables -L -v"

Yes, I can call the phones, they ring, etc, and call call out, just no outbound

Asterisk that could cause it, e.g., different ports, protocols, 
connection/discovery methods, etc?

Thanks,

Some way you should have a udp filter between you box and your phones. I see
that before.

Can you call those phones?

Asterisk/phones work perfectly within our LAN.  Asterisk box has a public IP
- no NAT or firewalls.   When I take the phones to a remote location (again,
public IP - no NAT or firewalls that I know of) the outgoing audio does not
work.  I can hear the other party, my phones ring, I can dial out, etc, but
the other party cannot hear me (even if I dial #'s, etc).

Any ideas?

Thanks,

Ross
