I experienced the Callcentric issues too. Their website showed the device as unregistered even though it was registered when I saw the Linksys PAP2.
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.
Oddly, at the time, the two ATA's that failed were using DNS SRV. The one that continued to work was not.
