Sorry, but your way above my level on this technology. So the way it is currently set up is NOT good?

Modem->Router->Grandstream

Brmstech,

Under Firewall for the DIR 655 change "UDP NAT ENDPOINT FILTERING" to "NAT ENDPOINT INDEPENDENT"

Here is an emulator: http://support.dlink.com/emulators/d.../Firewall.html so you can see what I am referencing.

Also at the bottom you will see a checkmark box for 'SIP' (ALG). Uncheck this box.

Once that has been updated & saved -- power down all network devices and then power back up all network devices.

Let me know how this works out for you, thanks!

Will do, thank you.

Thank you , VOIPoBrandon . . .Those changes to my D-Link 655 configuration have been installed and with the Grandstream plugged directly into the router . . .my VOIPo phone line currently seems to work fine. Still have my finger crossed that this condition continues.

Not a problem. Glad to be of help! Do let me know if you run into any further issues, thanks!

Keep in mind the Motorola modem is still in the mix. If you need to do nothing else then wonderful! But the modem has a firewall and could potentially come to be an issue. Get a ticket in and proceed with that knowledge if needed.

Good Luck!

Thank you, chpalmer. . . Will do.
