Dear John,<br>
<br>
The documentation on your website is a bit limited. I have some
questions:<br>
- Have you implemented an opensource SIGTRAN stack for Asterisk or an
opensource connector from Asterisk to the proprietary Dialogic SIGTRAN
stack?<br>
- Can you provide some diagrams on your website/wiki of the
network/protocol architecture?<br>
- Under what licence is the software licensed?<br>
<br>
Best Regards,<br>
Amish<br>
<br>

<p class="MsoNormal"><font size="2" face="Arial"><span
style="font-size: 10pt; font-family: Arial;">Our open source DiaStar
server can act as an SS7 gateway to
Asterisk. DiaStar has been available since last fall, but has only
recently
been qualified to work with SIGTRAN.<o:p></o:p></span></font></p>

<p class="MsoNormal"><font size="2" face="Arial"><span
style="font-size: 10pt; font-family: Arial;">It uses our DSI SIGTRAN
stack for ISUP signaling, and is integrated
directly into the Asterisk dialplan. You would just need to supply the
dialed
number and a technology type of “ss7”. Installing and setting up
a DiaStar server is quite easy. The only real work needed to get it
going is
the usual SS7 configuration against your carrier’s SIGTRAN
implementation. <o:p></o:p></span></font></p>

<p class="MsoNormal"><font size="2" face="Arial"><span
style="font-size: 10pt; font-family: Arial;">I should mention that it
uses Dialogic’s DNI T1/E1
boards (single – octal spans) for bearer channels rather than Digium
boards.<o:p></o:p></span></font></p>
