What solution to choose for a call center (outgoing calls) for 2-3 operators?

Question

Call centers

Interested in what to choose for making outgoing calls from a computer?
It is important that it be possible to integrate with CRM (so that you can link a call record to a client card in, for example, AmoCRM) and make the cost of outgoing calls as cheap as possible.
Thank you!
PS options for other budget CRMs are also being considered

It allows you to connect your telecom operators for outgoing calls, which most other SaaS PBXs do not have
