Before I completely bail on this phone, I am hoping someone here can provide me with the help I need to get it working. The Allworx vendor has been of NO assistance.

I am trying to configure this phone to work using a Belkin router connected to a cable modem from Time Warner/RoadRunner. The cable modem has only one ethernet port. Since I need to use that to connect to a wireless router, I cannot plug the phone directly into the modem.

Here is a list of steps I have taken to determine where the problem occurs:

1. Tried connecting the phone directly to the modem. Bravo. It worked perfectly. Again, since the modem has only one ethernet connection, this set up will not allow me to connect to the internet. I do know that the issue is not with my ISP nor with the cable modem.

2. I have rebooted the modem, then the router, then plugged the phone into the router to ensure it is recognized as a new connection. I then rebooted the phone. One way audio.

3. Within the router configuration, I have: a) Mapped inbound ports 2088 (UDP), 5051 (TCP & UDP), 5060 (TCP & UDP), 5061 (TCP & UDP), 5071 (TCP & UDP), 8081 (TCP) and 16001-16010 (UDP) to the same Private IP address private ports. b) disabled security. c)Disabled the firewall. d)saved all changes, rebooted as described in #2 above. One way audio.

4. I tried all of the same as #3, but used ports 16384-16393 instead of 16001-16010. One way audio.

5. I called Belkin technical support. They confirmed all settings then said there must be more Allworx ports.

6. I requested assistance again from Allworx (who initially said the ISP had some sort of filters that were causing the problem. See #1 above. It is not the ISP.) They copied and pasted a section from the Allworx knowledgebase that contained the ports I had already opened.

Can someone PLEASE help??? What am I missing??
