said by patnitop:That is what I saw last evening. Their website said unregistered, phone calls did not work, but my local ATA webpage said registered. My local ATA gave me dialtone, but could not dial out.
I experienced the Callcentric issues too. Their website showed the device as unregistered even though it was registered when I saw the Linksys PAP2.
Oddly, at the time, the two ATA's that failed were using DNS SRV. The one that continued to work was not.
