looking for a way to share BLF state between servers

[Kriss]

Hi there,

Well, everything is pretty much in the title : using 5 server running Elastix 2.4, i need a reliable way to share BLF status between my 5 IPBX.

I have heared about doing it with res_ais, or, by using a XMPP server.
Do someone got any experience on it ?

Any experience or advice welcome !
