[asterisk-users] Asterisk Peaking and 91 Calls And not a Dime More!

[Nick Khamis]

Hello Marie,

Increasing the rate got us up 2 folds, Thank you so much for your
help. We have a clustered asterisk setup, and it seems like 200
concurrent calls at 70% cpu is how we can keep these machine humming
comfortably.

Kind Regards,

Nick
