[Asterisk-biz] lowest voip service with IAX2 termination

[Brandon Patterson]

800 calls are not free. The called party pays the bill. Every call takes up 
so
much bandwidth and the equipment to process that call PSTN or VoIP. A
carriers like MCI for example has alot of capacity and when you are a PSTN
customer MCI will be happy to allow you to have access to many calls in 
progress.
Unlimited, Free - never. VoIP providers use gateways between their equipment 
and
the carriers. Many carriers use a Session Border Control device between the 
VoIP
provider and their switch. In most cases this is where the limit on the 
amount of calls
becomes a problem. Carriers, VoIP providers and anyone with business sense 
is not
going to purchase mega amount of expensive equipment for customers that can 
be here
this month, gone the next.

* uLaw will give you the best match in most cases with the majority of 
providers/carriers.
** In band DTMF, RFC2388, T.38 are all things that are NOT supported on many 
of the major
networks. Until the markets started growing again these things are slow to 
happen. How do you
buy equipment when calls are selling at the carrier level for less than 1/4 
of a penny?



Same reason as they are free on PSTN lines, or, how does that change from
pstn and voip?
