# How do conference calls work?

Multiple participants, easy dial-in and flexible number assignment – with the conference room you have the option of designing group calls flexibly.

The conference room offers space for 25 participants and enables easy dial-in without entering a PIN. You can freely choose which of your local or international phone numbers should be linked to the conference room.

Once you have booked the room for group calls, it can be reached worldwide from all devices and is already usable during the test phase. It is possible to book multiple conference rooms per account.

The **booking of the conference room** is only available as **Admin** possible. You can cancel on a monthly basis.

The **conference room** book in the **account management** under **conference rooms**.

#### **Secure conference calls**

The sipgate conference room requires **no PIN**. Nevertheless, you always remain in control of your conference calls. How does that work? At sipgate, multiple accounts do not share the same conference room, because each conference room has its own phone number. The following features are available to you in the conferences:

* An acoustic signal that lets you know when you are the first person in the room
* New participants are announced with a signal
* Any new phone number can be assigned to the conference room at any time
* If required, the conference room can be switched on or off

#### **Start a three-way conference**

As is customary with a telephone switchboard, you can directly forward incoming calls **using a shortcut key** to other employees or groups. The same principle also applies to three-way conferences, where you can connect with two additional participants **connect** .

To do this, simply first **the first conference participant** call. Then add the second conference participant via **Transfer** to bring them in. Tap for this **\*3** and the desired **destination number** or **extension** and confirm the action with **#.** Now simply **\*5** press to connect all participants in the conference. Want to leave the conference? Then simply hang up.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.sipgate.de/cloud-telefonanlage/en/using-sipgate/telefonie/wie-funktionieren-die-telefonkonferenzen.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
