[asterisk-users] Asterisk as a media gateway

2014-01-31 Thread richard . seguin
I'm playing around in a lab, and I was wondering if its possible to have 
Asterisk act similar to that of a Avaya PBX, where we have media gateways do 
the heavy lifting.

This is what I was thinking of trying.

1.  One asterisk server will contain the logic of the phone system (ex: queues, 
extensions...etc). 

2.  The mains server will not handle RTP traffic,  it will send the RTP traffic 
to another system (another asterisk box?) for processing. 

At the end of the day, what I am hoping for is to have 1 brain, and mutiple 
work horse audio gateways that can be added and removed as needed.

Has this been done?  Can anyone point me to some documentation on how others 
have done this? 

It's always fun to play


Richard Seguin.

Yes, this is basically functionality for Asterisk. If you are using
SIP, you want to REINVITE media away from your core Asterisk box.  I
suggest picking up the book[1] and reading the chapter on connecting
multiple Asterisk boxes together.

[asterisk-users] asterisk as a Media Gateway

2006-11-14 Thread Osama Kamal
I am planning to use asterisk with Digium TDM2404E card as a media
gateway to terminate traffic to Cell phones. Anyone got this working
before with no problems, specially with Answer/Disconnect supervision?
Thanks

[Asterisk-Users] asterisk acts as media gateway for existing pabx ?

2005-05-31 Thread Jean-Louis curty
Hi, 

I'd like to realize the following setup  traditional phones -- pbx
(non ip )  -- asterisk --- ISDN network


is it possible to set up an asterisk server in such way that it acts
as gateway between a traditionnal pbx and an isdn network ( I'm in
France ). this to let people continue with their existing pbx + phones
and enjoy voip features ?

outgoing calls:
if yes,do I need isdn card dedicated to incoming calls from pbx to
asterisk and dedicated card from pbx to outside

and what about the setup for incoming calls... the call comes in
asterisk server.. how to dispatch the call back to the pbx if it's an
extension still connected to the pbx ?

I hope it's clear enough 

thanks 
jean-louis

Yes you can. I have done this for a while.

First of all, you need an ISDN card that supports the NT mode. HFC ones
work great with ZapHFC drivers (mode 0 = TE, mode 1 = NT).
The cable between both systems MUST have 2 100 Ohm resistances.
Depending on your PBX, you might need to power up the line or not (100V).

A full explenation is available here:

[Asterisk-Users] Asterisk as a Media Gateway Controller

2003-11-05 Thread Lal, Deepak (Contractor)
Is it possible to use Asterisk as media gateway controller? I know  * supports
MGCP, but does that also imply that I can use * to control any third party media
gateway (such as one providing media conversion from E1 to AAL2). Any pointers
would help and be appreciated. - DL
