# Inbound calls from PSTN/mobile

## Overview

With a [Number](/components/number.md) you can receive calls from PSTN and mobile network to your SIP via a [Connection](/components/connection.md) or through a [Trunk](/components/trunk.md). Same [Number](/components/number.md) can be used for inbound calls by a single [Connection](/components/connection.md) or [Trunk](/components/trunk.md) at the same time (for outbound calls number can be shared [Outbound calls to PSTN/mobile](/how-to/outbound-calls-to-pstn-mobile.md)).

Let's see how to configure this on your account.

## PSTN/mobile to your SIP via Connection

1. Go to your Connections tab at [app.voipnumber.net/connections](https://app.voipnumber.net/connections) and open selected [Connection](/components/connection.md).
2. Open `Number` settings and select your [Number](/components/number.md) from a drop down.
