# Enable or Disable Call Waiting

Call Waiting lets a second caller reach you while you are already on a call. Say you are talking with a coworker and a customer dials in: rather than sending the customer straight to voicemail, you can put your coworker on hold and take the new call. Turn this behavior on or off in the Cloud Voice App whenever it suits you.

## Turn on Call Waiting

1. On the **Calls** page, tap your account in the top-left corner.
2. Open **Settings > Advanced**.
3. Enable the **Call Waiting** switch.

With Call Waiting on, a second incoming call plays an alert tone during your active call and gives you three options for the new call:

- ![Hang up icon](/images/pbx/hang-up.png) **Hang up**: end the call in progress and pick up the new one.
- ![Reject icon](/images/pbx/reject.png) **Reject**: decline the incoming call and stay on your current call.
- ![Answer icon](/images/pbx/answer.png) **Answer**: put the current call on hold and answer the new one.

:::caution
**Hang up** ends the call you are already on, not the new one. If you only want to decline the second caller and stay with your current contact, tap **Reject** instead.

:::tip
Once both calls are connected, tap the banner at the top of the screen to move back and forth between them.

2. Open **Settings > Advanced**.
3. Disable the **Call Waiting** switch.

With Call Waiting off, callers who dial in while you are on a call cannot break through. Depending on your [When Busy forwarding destination](/pbx/mobile-client-user-guide/presence-settings/#presence-settings__when-busy), each caller is either asked to leave a voicemail or routed to the destination you configured.

:::note
Because a second caller never rings through when Call Waiting is off, set your When Busy destination first (voicemail or a forwarding number). Otherwise those callers have no fallback and may simply be dropped.
