OPENSCAPE BUSINESS S Simultaneous call

[Rafijunior]

Hi everyone,
Please help me with this topic.
I have customer, which want new solution. There are ~3000 users, and I mean, will make 4 virtual machine's with OSB S (redundancy etc.) But i have a question. Can i make minimum 500 simultaneous call beetwen operating system (OSB S), or/and make simultaneous call outgoing?
Thanks

I don't know much about the OSB but I think that a larger PABX like OpenScape 4000 or OpenScape Voice would do that work easily.
