With regards to #3, the advantage of putting in a PRI is that you get
23 or 24 channels that are absolutely reliable and have signal/voice
quality that is essentially as good as it gets. A PRI has got to be one
of the most reliably engineered basic services that a telephone company
can offer. With a PRI, you can expect approximately one hour of
downtime per year. Even with a fairly reliable Internet connection, I
think you have to expect more than one hour of total outage time per
year (which consists of approximately 8700 hours) on a VoIP
termination/origination service. <br>
<br>
The major disadvantages of using a PRI of which I am aware are that you
are limited to 23 or 24 channels on a single line, that you have to pay
for the PRI line, and that long distance termination over the PRI line
may be somewhat more expensive than what you could arrange to purchase
over SIP or IAX Internet trunking. <br>
<br>
As far as companies go, VoIPJet offers good rates but their terms of
service are completely ludicrous and do a good job of steering me away
from that company no matter how good their service may (or may not) be.
As a matter of fact, I am prohibited from disclosing the fact
(according to VoIPJet's terms of service) that I am now or have ever
been their customer (if indeed that were to be the case)! WTF? <br>
<br>
I am currently testing Teliax and have had good luck with them, but
have only been testing them for a couple of days. If their service
continues working as well as it has been, then I see no problem with
using them as my primary gateway to the PSTN given the level of
reliability that my system requires (which is lower than that of the
public-switched telephone network itself).<br>

<br><font size="3"> </font>
<br><font face="Arial" size="2">1) If we do use Asterisk, what would be a
good billing system to use to keep track of thousands of customers minutes?</font>
<br><font face="Arial" size="2">2) Are there are any good back end software
available for Asterisk in which our customers could log into and view their
usage, etc?</font>
<br><font face="Arial" size="2">3) We are currently testing the Asterisk
system using VoIPJet over an IAX connection to our Asterisk system.
Would their be any benefits or disadvantages to putting in a PRI line instead?

<br><font face="Arial" size="2">4) What is some good company names to purchase
DID's and VoIP termination from? I have been looking at VoIPJet and
Teliax. I also am a member of DIDX. DIDX does not seem to have
any numbers in the area where I will be marketing first.</font>

<br><font face="Arial" size="2">I have read some solutions to all my answers
above on the Wiki, however, I would like some comments from people who
have actually gone through his process. As we all know, it is much
easier to put in a good system from the beginning, then have to switch
everything over once its running.</font>
