Just noticed my Simonics GV service is showing in my Asterisk as "UNREACHABLE".
Checking out their web page, I see this notification in small print at the bottom of the page:
Google Voice Gateways gvgw1 and gvgw2, and Fax by E-mail will be offline for maint. Saturday Feb 9, 8pm-12a EST. Faxes sent will be queued.
