150 Concurrent calls

Hi all, i am planning to configure freepbx for atleast 150 extensions and the might do concurrent calls. So i am wondering on the server side resources for example what kind of server should i use or how many rams, etc, and also bandwidth.

How does a 150 extensions = 150 concurrent calls?

equal or more than Intel Core i5

Take this with a pinch of salt

Worst-Case Server Recommendation
CPU: 8 vCPU
RAM: 16 GB
Disk: 250 GB SSD
NIC: 1 Gbps
Bandwidth: 50 Mbps symmetrical (minimum if G.711)

I’ve done 300+ concurrent calls over Asterisk with a system half of those specs and it barely broke a sweat.

It would take about 15Mbps (symmetrical) or so to support 150ish concurrent calls at g711.

Different Asterisk-based multitenant solution. 8 vCPU/8GB RAM. Just stress tested and was able to do 200-250 concurrent calls no issues. I stand corrected. Thanks for the correction

Was is recording every call?

yes :smiley:
