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.
 
One Business S has maximum 250 trunk lines.
 

I don't have any practical information on extreme tuning. Look at the address

Hints for all Providers​

  • Concurrent calls via ITSP (depending on the available bandwidth and used Codec).
    • 30 for OpenScape Business X1
    • up to 120 for OpenScape Business X3 / X5 / X8
    • 180 for OpenScape Business S
