[asterisk-biz] Unlimited DID

[Jai Rangi]

I feel that most of the folks in asterisk community are very smart and they
know what they are doing. In fact some of you are exceptionally good.
Anyone who get in the business and want to offer this kind of service must
have to spend tons of hours and lots of money before they offer service
specially to the people who know all tits and bits of technology.

To be honest I believe we have done all kind of testing we can think of. But
does it mean that we are never going to have problems? I don't think so.
There is not such thing called 100% just like there is no such thing called
unlimited.
Example yesterday I called my Wife cell phone (from Verizon to Sprint) 5
times and she did not get a single ring. Her phone was showing 4 bars of
signal. Now these are level 1 carriers.

The idea is how many 9s you can support. Based on reliability/availability
of service in last 6 months I would put myself on 3 9s.(99.9%). Again
Remember we offer FREE trial before you buy.
