How to organize a call center?

Question

CRM

Good afternoon!
Bottom line : there is a call center consisting of 5 telephone operators, which is mainly engaged in receiving incoming calls, recording people for an upcoming bus flight. The task of the operators is to fill the bus to the maximum. At the moment, operators work through a banal database through Excel. From time to time there is a need to load the bus by calling potential customers on a ready-made database in the same Excel. All numbers are connected to the Virtual PBX Megafon. There is also one operator that processes flight requests through the feedback form on the website, WhatsApp, Telegram channel and online chat on the website, VKontakte and FB groups.
Question: what software solutions can be used to manage a call center, see where a client signed up, at what time, for which flight. You also need the need to distribute customers to certain operators in the event of a call. Ideally, I would like to combine the employees of the call center and the Internet manager into one database, where the manager will be able to observe who has done how much work and for which flight there are not enough people.
I tried to consider crm solutions from Bitrix 24 and AmoCrm, but the specifics are not quite suitable. We do not collect leads, we do not carry out sales, most of the clients contact us on their own using the phone.
Thanks in advance for your reply.

Use SIP and virtual PBX: there are plenty of WEB<->SIP integration modules.
CRM - any.
