How to make a shared asterisk phone book?

Question

Asterisk

is it possible to make a common phone book for all users?
so that in the sip client all the numbers of
clients on android and ios are immediately clogged,
perhaps there is some kind of alternative solution to the problem,
otherwise when a new client appears, it’s not very easy to manually score more than 50 numbers

Answer 1

A few questions:
Why these questions:
PS Another option, maybe you have some kind of CRM or accounting program like 1C: ZUP from where this data (contacts within your organization) can be exported to CSV and uploaded to the same gmail.
PPS Well, one more option. You can simply send data from one client (whose all these contacts are filled) to another, for example, via WhatsApp or mail, then you just need to open and save them on your device.
