[Asterisk-Users] Are IAX2 providers ready for prime time?

[Jim Archer]

Hi All...

I have been putting together a call center and I was hoping to use a VoIP 
provider who can terminate IAX2.  A participant here has been kind enough 
to help me off list, for which I am grateful.  I have called two VoIP 
providers, Coloco and NuFone.  Coloco has yet to return my calls and 
although I spoke with someone at NuFone yesterday, today when I tried to 
call to get service I got several "all circuits are busy" messages. 
Calling on the non-toll free number I left voice mail, but got no call 
back, or response to my email.

I looked at Voice Pulse, but have read here that there are issues with 
reliability.  They also seem set up for end user consumers, as do a few 
others.

So I am starting to get a bad feeling about VoIP providers.  They seem like 
really, really small outfits.  Realistically, is the service provided by 
VoIP providers reliable and stable?  Can you bet your business on it?  How 
often does it go down?

I would appreciate any feedback.  Thanks!
