Kamailio FAQ
How many simultaneous calls can Kamailio handle?
On well-chosen hardware, tens of thousands of SIP dialogs are possible. Limits depend on server performance and configuration complexity.
What limitations does Kamailio have?
Kamailio is easier to scale, but PBX features are harder to configure.
Can Asterisk be used instead of Kamailio?
Yes, but it depends on the use case, because they solve different problems in VoIP. If load is low (up to hundreds of calls), Asterisk can fully replace Kamailio without losing functionality.
But it is better to combine them: Kamailio in front for signaling, Asterisk behind for media.
