Question

Asterisk

Poke please in technology / software.

Problem 2: many clients live in a remote area, so some of them don’t even have faxes, they run “to the next pharmacy”, so e-mail and others like it are excluded.
Problem 3: the call is usually to another city or country, so it is advisable to start everything by IP.
Task 1: how to arrange everything in a smart way so that everything works simply? Local asterisk specialists say that they have problems with faxes.
Task 2: recommend free CRM, preferably integrating with asterisk.
