3CX Queue Callback Limits

[itnetworks.gr]

Greetings,

We have configured a queue with 5 agents and Callback enabled. The PBX may receive more than 20 calls during specific timeframes and we would like to know for the Callback limits (how many phone numbers can it store and perform a callback) and how they are prioritized.

Thank you in advance.

I am not aware of any limitations, and it is a queue -- first in, first out.
