Scaling to 20000+ concurrent calls

Hello Guys,

is there a way to scale a vicidial mega cluster to 20000+ concurrent calls with Galera or any technology available around.

Thank You..

We'd usually suggest breaking that up into multiple clusters. We have done it before on VICIhost with 10 separate clusters placing outbound calls and one "closer" cluster with agents handling transfers from the fronter clusters. That's if you need full VICIdial functionality. If you're looking for more sparse features on the outbound side you could probably do it with a lot less hardware, but it wouldn't be able to do everything that VICIdial currently does.

If you build a system that generates massive calls (pure robodial) and only passes the calls to the Vicidial Cluster upon answer (as inbound to Vicidial), you no longer have a limit on the calls, technically. This requires (as Matt pointed out) knowledge that you only need mass outbound calls. Would also be nice to know if your goal is to play a recording and await "press one" before transferring to an agent or if you have some other call center model in mind.
