[asterisk-users] SIP/IAX2 Provider with fallback dialing?

[Steve Finkelstein]

Hi all,

I was curious if anyone can recommend a company that would work with
small businesses, and capable of using a fallback number (mobile
phone, home number etc) in the event SIP or IAX2 peering was to
terminate because of some outage.  This could be useful when you do
not have a backup T1 PRI, etc.

Thanks all,
