[SR-Users] disptacher failover

[Daniel-Constantin Mierla]

Hello,

it is a matter of the used dispatching algorithm. For a call, first gateway
based on algorithm is selected and the rest, starting with the next, are
added in a list of avps to be used for failover purposes.

So if you do round robin and one gw is down, if you don't mark it as
inactive, 2 calls are going to the next one after the one that is done and
1 call to the third gw, and so on.

Cheers,
Daniel
