[asterisk-biz] Starting a VOIP Business

Sun Feb 3 15:19:41 CST 2008

As far as I can tell, as long as you are talking about wireless broadband, 
i.e. the ISP installs the antenna/router at the customer location, as long 
as they have a well engineered network everything works great.

We have about a dozen such companies selling our turnkey VoIP and hosted PBX 
and they have none of the issues being discussed here.  As long as you have
good control over jitter
goot control over latency
no common issues with congestion
and public IP addresses

Everything works fine.  Our smallest wireless broadband client has about 100 
customers on his network total, our largest almost 10,000.  We have seen 
some fail, but that was because they were selling crap wireless.  Good 
network = VoIP works just as well as on cable or DSL, bad network = blood 
bath. But no one should be surprised at that!
