Subject: RE: [Asterisk-Users] Asterisk as
a SIP/H.323 Router
Hi,
I took a look at
the architecture.
The way the
Cisco boxes will work if Asterisk in the middle is a Proxy, but it's
not.
You cannot
re-direct an incoming Voip call from one gateway to another, only a proxy can
do that.
The Asterisk in
this mode can only terminate the calls via the PSTN. If it attempts to
re-direct the call to the Cisco, it has to be via it's PRI interface (i.e.
Cisco PRI0-3 is connected to the PRI interface of the Asterisk Location
B.

Hi All,
I've been spending the
last month experimenting with Asterisk, and I must say that all results
point
to a very positive outcome.
Now, i've been asked the
following question: Is it possible to put an Asterisk box between 2
Cisco
routers or other SIP complianet equiment, then routing SIP/H.323
calls between the two routers?
Here's a drawing that will
explain:
+--------------+
+----------+
+--------------+
PRI
|
|1.1.1.2
1.1.1.3|
|1.1.2.1
1.1.2.2|
|
---->+ Cisco Router +-------------------+ Asterisk
+--------+--------+ Cisco Router +-->
PRI0-3
| Location A
|
|Location B|
|
|
|
+--------------+
+----------+
|
+--------------+
|
|
+--------------+
|
1.1.2.3|
|
+--------+ Cisco Router +-->
PRI4-7
|
|
+--------------+
The question here is this:
A phone call is is made to the router in
location A.
The Cisco router routes the call via SIP to the Asterisk Box at
Location B.
According to a set of rules on the Asterisk box, the box would
route the SIP/H.323
to one of the the other Cisco boxes, in order to
terminate the call.
What do you think, is this
possible?

Excuse me for the poor ASCII art, I
didn't want to attach a Visio or a PDF
file.
