Simple SIP Proxy with auto answer function

Question

Asterisk

Bottom line: you need to install a simple SIP-Proxy behind a remote asterisk server, but there are a number of necessary conditions:
1. The presence of the ability to automatically "pick up" any incoming call and only then redirect it further (even just one user can), preferably preserving metadata. Provided that there is already an active call - do nothing.
2. Ease of deployment and configuration is highly desirable.
3. GNU/Linux, CLI-only
I wouldn't want to deploy a full-fledged asterisk, because I'm dealing with VoIP for the first time, it will take a long time to master it.

If there is no desire to understand, formulate the TOR and look for an artist on freelansim.ru for example.
