usa2k,
No, I'm not saying the HT-286/486 is not good device, it is. After all, I use the HT-502 which works flawlessly as well (yes, I was around when VOIPo was battling them) but GS finally fixed them. I've used the HT-502 in front of and (currently) behind my router without an issue. The PAP2T is a good device as well, but Atlanta having the largest local calling area in the nation (3 area codes and about to go to 4) the last area code with the most available numbers is servicing a huge geographic area, causing some calls to go thru several switching stations before it 'finds' you, which would consistently overflow the PAP2T and force a reboot of the device. Every time my virtual number was called, you could see the PAP2T reboot and if I was on the phone when that occurred, the call was abruptly broken. The HT-502 having route capabilities doesn't suffer the same drawbacks as I suspect most ATA's with route abilities are immune to this issue as well.
