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.

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.
Cheers,
Abdul
