[TriLUG] Survey: Best simple SIP vendor?

[Brian via TriLUG]

Hi,

This is more a matter of curiosity than anything else at the moment, but 
say I wanted to run an Asterisk instance, and needed a VoIP vendor to 
give me a bare minimum service (e.g. a phone number and MAYBE rollover 
to another number if the connection is down).  Does anyone recommend a 
good vendor for that?  Used to be, before MS gobbled it up, Skype could 
be used by Asterisk, but I'm pretty sure that's long gone now..

Cheers,
-Brian
