Switched routers - now no service

also- dont assign a static address in the dhcp range of your router as a general rule.

You might try turning all port forwarding off to test and see what happens.

Initially after setup, I did not enable any port forwarding, and it did not work either. I enabled the port forwarding in hopes of getting it to work, to no avail.

I have the D-Link DIR-600 router.

I assume you have checked the other router settings, for example outbound filters. Also, make sure the ALG for VoIP is turned off, and SPI is turned off.

I turned SPI off, same result. I'm not sure what ALG is? I tried to access the PAP2t, but it wants a username and password.

ALG is Application Layer Gateway. I have a different D-Link router, but the setting on mine (DGL-4100) can be found under Advanced/Firewall. There are different ALGs for various applications, including one for SIP. I can almost guarantee that if the SIP ALG is checked, it will cause your problem.

The ALG is short for "Application Level Gateway". IIRC, the DLink routers do have one for SIP (which is the one for VoIP that needs to be turned off). Look under your firewall tab. The box on the bottom should NOT be checked. See image below...

Well, the mystery continues. I found the setting and it was checked. I unchecked it and restarted both devices and now there is no dial tone at all. I rechecked the box and restarted, and it's back to the original condition described in the first post. At this point, I am at a loss. Thanks you to everyone for all of the help so far.

Just as proof of concept remove your router and connect your ATA directly to the modem. Confirm that your phone service works perfectly - this will also confirm that introducing the router causes the issues.

Even though you get no dial tone now, I think in the end the ALG setting should be unchecked. Do your logs indicate what is happening? Do they show packets being blocked or dropped? When you go to VPanel, does your device show as being registered?

Sometimes you have to wait a little while until things clear -- e.g., there may be some bad addresses cached in the servers or the router. I'm sure Support will be able to fix you up, particularly if they can look at the adapter logs. It's just too bad this had to happen on the weekend.
