[Asterisk-Users] Clustering

[Douglas Garstang]

Uhm, No.
 
We have multiple Asterisk boxes. OSPF only fails over between interfaces in a single Asterisk system.
We're not using regexten (cuz there's no frikkin docs for it!!!). We're using OpenSER's send() command to forward registrations from a phone to all Asterisk systems.

Regarding OSPF, so your saying you have multiple * boxes setup with same exact config and then just have OSPF fail everthing over to the new server if it cant get to it? That makes sense, just never of even thought of doing it that way. Heck, if you want to get real complex just run BGP and you could then setup priorties for each server and all kinds of cool stuff.

Are you then using regexten on all servers so when a * tries to make a call it can find where to go, or are you using something else?

Thanks!
Ron

How does OSPF tell the remote end (assuming he does not know your setup) start sending RTP packets to the other interface?

No, only if a network interface in the server fails. We have two network interfaces per system (actually we have four, but two are on a private network with a MySQL server). If one of the network interfaces fails, OSPF will switch the default route over to the other interface pretty quick smart. There's probably a little luck involved here too.

        So you are actually able to maintain a call in progress even if the server 
        its connected to fails (by routing to another)?
