Can I make SIP calls without Asterisk/FreeSwitch?

Question

Asterisk

There is a database of numbers, you need to automatically call them (autoinformer) via SIP. Is it possible to do without Asterisk and similar tools for this purpose, using only a SIP client such as this https://github.com/tmakkonen/sipcmd?

Answer 1

Of course, it all depends on the complexity of your scenario. You can use sipcmd, baresip (automated via http), pjsip (this is already a library on the basis of which you can create your own client).
Asterisk and Freeswitch are PBX, if your script is simple enough you can do without them.
