How to set up access rights to the Bitrix24 menu?

Question

1C-Bitrix

It is necessary to launch a call center on an outsourcer, they wanted to do it through an extranet, but telephony cannot work with extranet users. It was decided to create them on the intranet and give them minimal rights and access to a few menu items. But I didn’t find anywhere how to restrict access to them, I found it in the admin panel, but there are rights to 1s-Bitrix, I also found access rights to CRM. And how to set the rights, for example, they did not see some separate items in the menu on the left, for example, a calendar. disk, etc. I have a boxed version

Answer 1

And how to set the rights, for example, they did not see some separate items in the menu on the left, for example, a calendar. disk, etc.

Without editing the menu file itself (.left.menu_ext.php), such a restriction cannot be made.
The product out of the box is not designed for such restrictions.

Answer 2

There was a temporary task, to start a call center for the project, but so that they would not bend anything inside B24. Weighed all the risks and solved the problem differently. I connected the Speed ​​Call service, there is integration with B24 in both directions, separation of contacts by operators, and a huge plus for hiding phones from the operator (he sees asterisks and two digits at the end of the number in the card). I set up the creation of leads in B24 by the status of the call, in B24 everything is pulled up: result, comments, conversation recording ... I recommend it in short!
As a result, no one else enters B24 in dirty shoes, everything is neat and under my control.
