Is there a high reliability build of Asterisk?

Question

Asterisk

Which version or build of Asterisk is the most fault tolerant and stable under high load?

Answer 1

freepbx

Answer 2

rather than Asterisk, it will be FreeSwitch - it was designed just for a heavy load

Answer 3

For the requirements of the greatest reliability, you should choose:
1) The longest supported LTS branch of asterisk at the moment
2) When installing Asterisk, disable all unnecessary modules
3) Provide sufficient resources (network, processor memory) - there is no universal recipe here
The rest depends on the functionality that you need to implement it on asterisk - just a wrongly written dialplan can already ruin any stability.

Answer 4

From experience, asterisk is reliable. But as for the machine on which it is launched, I derived the following requirements for myself:
1) 2 GB of RAM (provided MySQL + Asterisk)
2) 2 processor cores (not critical)
3) high-quality Internet channel - for a normal system - stability , for highly loaded additional requirement is the channel width.

Answer 5

In the Elastix distribution, the Asterisk build has always been highly reliable and stable. According to experience, ~ 20 thousand incoming per hour holds without problems, on the server ~ = core-i3 / 8Gb
