[asterisk-users] Two Asterisk machines for redundancy

[Aaron Roberts]

You might want to look at a product called "astribank" made by Xorcom, which does a pretty good job of giving redundancy on E1.  In their redundant asterisk setups, they use drbd to mirror configuration and data between asterisk hosts.

using realtime functions has been added since 1.2.x,
about E1, I thought  you are using external voip gateway like cisco,... if you are using e1 as dahdi driver you have not redundancy option(as I think)

Database: but this require to use Asterisk version that support Database, correct? Which Asterisk version does this?

About DNS, please note I am talking about E1 connected to the server, so I was mean, in case first Asterisk down, then to send E1 calls to second Asterisk. I am not talking about IP Trunk. Any help?

Hi All;

I would like to have two Asterisk machines to have redundancy between them, so if first machine failed then we can depend on the second machine.

Because of this, I would like to know (if someone can advise me):

1) If I did modification on the configuration, how this will be applied to the other machine?

2) I am going to use E1s, so what is the method to be able to let the calls go for other Asterisk machine if first one is down (due to maintenance or upgrade)? Is there a switch or something can help in this?

Thanks for the help in advance.
Regards
Bilal
