How to establish communication with clients if there are a lot of developers?

Question

Skype

The situation is such that there is a customer, he comes to Skype, then after the statement of work is approved, he needs to be redirected to another person, but so that it is possible to "replace" this person if necessary. For example, how I see it all:
we throw a link to our site to a person, he comes in and sees login: password-> chat. In the admin panel of this particular user, messages can be redirected to any messenger which will be easier to do, the main thing is that you can choose who exactly to send messages to.
Everything would be fine if there was a customer service manager ... but alas, he is not. Maybe I made something very cumbersome for myself? But now we have: we all sit in the same Skype chat and monitor the messages of the clients assigned to us, everyone reads the chat and therefore notifications of new messages immediately disappear and you need to constantly check, what if a person wrote something ... and if such people 5+ or 50+?))))
Share your ideas, thanks!

Answer 1

Slack

Answer 2

For example, I am generally against the fashionable movement "let's do without managers."
Let's call the manager a Scrum Master, a Team Lead, whatever. But when real work "in the field" intersects with management, we see the most common conflicts of the big and small worlds. Scandals at home -> mess at work.

Answer 3

Who will be the first to show initiative and start to steer clients, then will steer the whole business.
