Which chat systems provide an operator?

Question

Outsourcing

Which of the existing online chat systems on the site are outsourced by the operator? SiteHeart used to provide, but now they say no.

Answer 1

Here is the only solution:
Letitchat: chat + bots + operators
(3in1)

Answer 2

This service should rather be sought not from chat hosters, but from call centers.
For example:
- www.infotell.ru/ru/uslugi/other-services/operchat
- kolocall.com/price
etc.
Found by Google for "call center online chat".
