I would like to understand Asterisk capacity / dimensioning limits from the architectural prospective.
Imagine that you have theoretically unlimited hardware resources on your server.
In this case, what is the capacity limit of a single Asterisk node - in terms of the number of endpoints and / or concurrent calls?
Let’s assume the following:
- only SIP or PJSIP channel driver is enabled
- only basic functionality (i.e. 2-way calls) is used.
- up-to-date Asterisk version (13 or 15) is installed.
Of course, in the real life you will never get an infinite hardware capacity.
However, there should be a boundary where it will make more sense to set up a second node connected to the first one via trunk - rather than upgrade the only server.
Do you have any practical examples of running large Asterisk systems on a single node? How large are they?
