Hi John,<br>
<br>
What advantage does the architecture on the following webpage provide? <br>
-
<a class="moz-txt-link-freetext" href="http://wiki.projectdiastar.org/index.php/Project_DiaStar_Server_-_SIGTRAN">http://wiki.projectdiastar.org/index.php/Project_DiaStar_Server_-_SIGTRAN</a>
<br>
<br>
Would it not be better to provide a M3UA implementation that resides on
the Asterisk server rather than a separate server?<br>
The use of Routing Contexts and Routing Keys in M3UA would help to
distribute traffic across multiple Asterisk platforms.<br>
<br>
Cheers,<br>
Amish<br>

style="font-size: 10pt; font-family: Arial;">DiaStar is an open source
application which is used to
connect our proprietary DiaStar Media Engine (a variation of our HMP
product)
to Asterisk. It uses the Woomera protocol to connect to a chan_woomera
channel
driver on the Asterisk side. Dialogic DNI boards provide a T1/E1
interface to
the PSTN for CAS, ISDN or SS7. For SIGTRAN signaling, it uses our
proprietary
DSI SIGTRAN stack. <o:p></o:p></span></font></p>
