I just called tech support and was told that I'd done everything they could think to suggest and that I need to try another modem. I'll do that...when I can find another modem. In the meantime, I thought I'd post here to see if anyone has any bright ideas...
Hardware details:
T-Link TD-W8960N modem / router - latest firmware
Linksys PAP2T
The PAP2T is plugged directly into the modem.
Here's what I've done so far:
- Static IP for the PAP2T (although it's allocated by the TD-W8960N via DHCP as a static lease based on the PAP2Ts MAC address)
- Port forwarded 5060-5061 (TCP/UDP) and 10000-20000 (TCP/UDP) to the PAP2T (I checked a million times - it's the correct IP address)
- when port forwarding didn't work, I put the PAP2T's IP address into DMZ (again, I checked the IP address many times)
- Disabled SIP ALG on the TD-W8960N
- Factory reset the PAP2T and re-provisioned from XNet
- Disabled SPI Firewall on the TD-W8960N
I've read all the posts (Geekzone and abroad) that I can find, and I'm running out of ideas. It seems that others have VOIP working (even with VFX XNet?) with my hardware combination.
