Thanks Cary,<br><br>The first topology we are working on should be the best way then.<br><br>Asterisk will answer SS7 calls, route them to the ISDN channels to be terminated by the AS5300 as they were doing before. I think TDM-2-TDM shouldn't be that much of a problem eh? No further equipment needed?<br>

<p class="MsoNormal"><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy;">I don’t think Asterisk can convert
TDM to IP. It does convert TDM to SIP which is then sent out over IP. What
you want to do is have it do the TDM/Modem conversion without the PRIs and
Cisco Gear.</span></font></p>

<p class="MsoNormal"><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy;">There used to be a way to do this, and
maybe still is but not just with Asterisk perhaps.</span></font></p>

<p class="MsoNormal"><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy;">I know that Ascend/Lucent TNTs (and I am
sure some other equipment) could take TDM trunks, which could be SS7 trunks,
and convert them to IP. </span></font></p>

<p class="MsoNormal"><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy;">The point in this is that they are SS7
based. You can take SS7 trunks from either the Asterisk box or direct from the
Telco and convert them to IP.</span></font></p>

<p class="MsoNormal" style="margin-bottom: 12pt;"><font size="3" face="Times New Roman"><span style="font-size: 12pt;">Thanks Cary,<br>
<br>
What happens is, the Telco won't allow the small company to resell the ISDN
connections, meaning, they bought the trunks and DIDs, then sold dialing plans
to route incoming calls through the PRIs out the Internet. This is not the
issue though. We definitely have to migrate to an SS7 capable platform, because
that is the only way the Telco allows them to resell the dial-up connections
(not ISDN), and Asterisk is the current bet.<br>
<br>
If we can get Asterisk to pick up those calls via SS7, then authenticate them,
send them out to the Internet, we would be achieving a %100 usage on the Digium
cards, because one of them wouldn't be used to talk to the AS.<br>
<br>
Can Asterisk do this?<br>
<br>
<br>
Thanks again,<br>

<p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size: 12pt;">Hello,<br>
<br>
We are working on implementing a solution for a medium service provider. They
were previously using a Cisco AS5300 gateway with some PRI trunks to receive
modem calls, then route them out the Internet.<br>
<br>
The Telco they were buying the trunks to discovered this configuration and
restricted them due to legal conventions, and stated that in order to continue
doing this, they would have to talk SS7 directly.<br>
<br>
We are planning on solving this by placing an Asterisk server with some TE410
cards talking SS7 to Telco, and another 4 ISDN ports talking to the AS5300 for the
dial-up to complete after authenticating against a RADIUS server.<br>
<br>
My questions is: can we use only Asterisk to complete/terminate the dial-up
connection, removing the AS5300 out of the picture?<br>
<br>
Current topology to be set-up:<br>
Telco --> SS7 --> TE410P-AsteriskServer --> ISDN --> AS5300 -->
Internet<br>
<br>
Ideal topology:<br>
Telco --> SS7 --> TE410P-AsteriskServer --> Internet<br>
<br>
<br>
Some posts talk about zapRAS being able to accomplish this, not quite sure
though<br>
<br>
Sounds like possible:<br>
