<DIV><FONT face=Tahoma>We put a VWIC and a DSP in a Cisco 1720. The purpose will
be for a customer to use a T1 Crossover cable to connect the 1720 into their
existing PBX system. It'll be a "Virtual T1 PRI" type of thing. The Cisco 1720
will make the conversion to SIP and send it to our Asterisk server. As far as
his PBX is concerned, it's talking to a standard T1 PRI from the local telco or
whatever. </FONT></DIV>
<DIV><FONT face=Tahoma></FONT> </DIV>
<DIV><FONT face=Tahoma>The issue is Cisco routers don't support SIP
registration/authentication. I want this customer to be in his own context in
the extensions.conf file. </FONT></DIV>
<DIV><FONT face=Tahoma></FONT> </DIV>
<DIV><FONT face=Tahoma>What I was thinking is, if I remove "username" and
"secret" from the sip.conf for a standard user entry, but do a
"context=whatever and a "host=x.x.x.x" for his specific IP, if an
unauthenticated request comes in from that IP it should automatically put him in
that context, instead of the default one specific at the top of the file in the
[general] section. </FONT><FONT face=Tahoma>Also, if I forward several
DID's to SIP/customer1 (customer1 being what I put in brackets for this entry,
ie [customer1]) it should see the host=x.x.x.x and send it to that IP,
regardless of authentication. </FONT></DIV>
