Would be possible.

Have a look at DRBD!

Betreff: Re: [SR-Users] Redundancy between 2 Kamailio servers

Hello, 

I was thinking that if i store the contacts that are registered into my proxy in a database, like this:

.

.

# ----- usrloc params -----

modparam("usrloc", "db_mode",   3)

.

.

if (is_method("REGISTER"))

{

        if (!save("location"))

        sl_reply_error();

        exit;

  }

.

.

This way i would store the contacts in table "location", and then i could make a backup of the DB and restore on the other server...is that ok? or i'm missing something?

Thanks in advance for your help!

As I said at the top of my previous mail: HeartBeat (as it is the only
I'm used to).

Could be, or not. It doesn't matter too much.
