I have a cable Internet connection. My wireless router is a Belkin F5D7231-4 and is connected to my cable modem. My Handytone HT486 is connected to the router and is placed in the DMZ.

I'm trying to use Direct IP dialing to/from my Handytone and use X-Lite for this. Within the LAN, I can make successful calls from X-Lite to the HT486 and vice versa. But when dialing from an X-Lite client on the Internet to the HT486, the phone is ringing. But when answered, there is no voice. When dialing from the X-Lite client on the Internet to another X-Lite client on the Internet, everything works fine. This makes me believe that this is a configuration issue on the HT486. As the HT486 is in the DMZ, this could not be a port forwarding issue, right?

Any suggestions on how to resolve the "no voice" issue?

Is there a particular reason that makes you use direct IP dialing instead of using a service like FWD to manage the connection of each client through its respective router? I would recommend registering each client with its own FWD number and using that service to connect the two ends.

The reason for using direct IP dialing is that I use by SIP account for cheap international calls. The provider that I use does not allow calls between its users. Becuase there are no other providers that have this low rates, only direct IP dialing remains as an alternative.

The no voice problem has been resolved and was caused by low bandwidth at the other end.
