What tasks can Asterisk solve that cloud telephony services cannot?

Question

Design

If this is NOT a call center for a hundred places, but 1-3 operators.
1. Well, the timbre can be changed.
2. Cheaper, set VDS and that's it, you don't pay for each operator (150-500 rubles).
More complex routes/redirect logic?
What else?
Now you just need to integrate with the CRM system and read a lot of negative reviews on the issue of linking Asterisk with CRM.

Answer 1

Answer 2

Half of cloud telephony is an asterisk with additional goodies and technical support.
A clean Aster on your server - you install it yourself, configure it yourself, screw the buns yourself and support it.
Well, you can really mount any buns, and not just those that the vendor decided

Answer 3

read a lot of negative reviews on the issue of linking Asterisk with CRM

This indicates problems in CRM, not in Asterisk.
Any cloud PBX is a limitation, in one form or another.
In * there are no restrictions in fact, do what you want.
