No ring tones when firewall enabled - Xen Guest / Centos 5.2 / Freeswitch 1.0.3

Hello ..

With firewall rules enabled there is no ring tone on any outbound calls, only inbound calls.

Watching the network interface on the free switch server with tcp dump:

- firewall off - UDP stream bi-directional between freeswitch and the endpoint
- firewall on - UDP stream one-way (to freeswitch) from the endpoint

As there are no outbound rules from the server, this would lead to believe it's a freeswitch problem - but how so?

BTW - with the firewall enabled in-call voice is fine (ie: two way). It's only ring tone that's affected.

Puzzled.
