# Callflow

In a basic configuration there are only two requirements for our telephony to work: 

1. A central Omnidesk number for your customers to call (see [Numbers](https://docs.omnidesk.io/omnidesk/numbers#numbers), in the sample below: +13512312311). 
2. An agent with a browser or phonenumber.

That's it.
