Two telephony servers one carrier

[DomeDan]

No this is not some kind of bizarre video

This is the situation:
I'm trying to setup a telephony/web server at a remote office
that connects to my main server DB/web/telephony through a openvpn tunnel.

My goal is to have a secure connection between the two servers and use the main server to call the carrier with.

Code: Select all

                                                       agent agent agent
                                                             \ l /
agent --\                  [DB-data and IAX2-data]            \l/
agent ----> asterisk/web ------[openvpn-tunnel]------> DB/asterisk/web------> carrier
agent --/     10.0.8.2                                   10.0.8.1


A call on the main site seams to be working, only thing I did there really was changing the ip adress to the tunnel-adress (yes I ran ADMIN_changer_server_ip.pl)


Here is a call to 0046701212121 done on the remote site: (Asterisk CLI)

I'ts kind of working, but I would like to hear your opinions,
is this the proper way to do it?
should I use any other method?
can I do something in my dial-plan?


Both servers installed with Vicibox 3.1.15
both revision r1859 (admin build 120831-1523)

First off, I do not think this will work, mainly because the VPN tunnel is going to add considerable latency to the database connection. This will cause problems.

That said if you wish to continue down this path, you need to setup the two systems differently. First off you cannot use the cross server links that are in place. You will have to build your own. When you do on the main system put the context that the calls from the remote box as loopback-no-log. In loopback-no-log context put a dialplan entry that calls out through your carrier, but does not call the call_log agi script. On the remote system setup the carrier entry over to the main box just like you would any other carrier.

The problem with how you currently have the call flow setup is that you are not logging it on the remote box, and you are logging it on the main box. This is going to completely confuse Vicidial because the box initiating the call is not the one logging the call.

[DomeDan]

Yeah your right, It would probably not work,
just to get it working I white-listed the remote office ip-address and let the agents connect to my main server.
Now when they are working the server is walking on its knees, I need to separate the DB from the web/telephony to keep down the load.

And I don't what to go down the road with ugly hacks and get a non working system every time I want to update the vicidial system.

Thank you for your comment, It gave me more insight on the setup!

Domedan

Maybe you should consider a cluster ?
And just let your remote office logon to the cluster.

[DomeDan]

Yes, that's what I'm gonna do.
the setup will look like this when I'm done:
* HP DL360 G3 2x3.06GHz 2x76Gb 10k scsi raid1 web/telephony
* HP DL360 G3 2x3.06GHz 2x76Gb 10k scsi raid1 DB
* HP DL360 G3 1x2.80GHz 2x76Gb 10k scsi raid1 DB slave (just a simple replication)
