[Asterisk-biz] Inbound per minute vs. per port charge

[Max Clark]

Hi all,

I am looking for some guidance with inbound pricing. Lets say that a 
local TDM T1 circuit with unlimited inbound costs arround $600 (or 
$26/port). As I look at pricing options it seems to be more and more 
common to charge a fee (say $0.01/minute) for the inbound termination. 
This would mean that the provider is banking on 2,600 inbound minutes 
per channel to break even. Even with a 4:1 oversubscribe this is 650 
inbound minutes per month to break even.

I don't understand this math, it seems that the break even point for 
these channels is higher that what could be supported. What is an 
average assumed inbound minute/month number for telephone users? I am 
assuming that these minutes are going to be concentrated Monday-Friday 9-5.

What I am trying to get at is what is the oversubscribe rate being used 
in these models. Do I need to be concerned about busy signals and/or the 
company being able to support itself?

Your responses are appreciated,
Max
