# How can I fix issues such as background noise, echo and poor voice quality?

The first basic requirement for good voice quality is a **broadband internet connection**. The important thing is the speed: a single phone call over the internet requires about **100 kbit/s** (for both upload and download). Too little bandwidth can cause dropouts.

* **example**: Even with a standard DSL connection with 16,000 Mbit/s download and 1 Mbit/s upload, up to 10 simultaneous calls are possible.

Your internet connection is fast enough and yet it's still choppy? Here's a list of possible problems and solutions:

* **A cable is better than Wi‑Fi:** Sounds like a rule of thumb, and in most cases it is true. If your router and computer are connected to the internet via network cable, you get more out of your bandwidth.
* **The right headset:** There are many good Bluetooth headsets. Nevertheless, wired headsets are usually faster.
* **Strong interference on the line:** If your voice is accompanied by strong interference, check your microphone settings under **Start -> System Settings -> Audio Settings.**
* **Audio input and output:** Perhaps your audio settings are not quite correct. For example, you hear the call through the computer speakers even though you have a headset connected. Usually, in your operating system's system settings, you can select the appropriate audio input and output for your device and also adjust the input level – that is, how sensitive your microphone should be.
* **Do you hear yourself, and twice?** This is usually due to your conversation partner(s). They hear you so loudly - perhaps through computer speakers - that your own voice comes back to you through the other person's microphone.
* **Still echoing?** You have already checked all the technical settings and yet your conversation partner still hears you as echoing? The first option would be to lower your microphone's input level (in your operating system's system settings). Another solution may sound rather banal, but perhaps you are making the call in an unsuitable room. If there is generally a lot of echo in your room, then unfortunately even the best technology will have difficulty compensating for this problem.
* **Echo on your conversation partner's end?** Of course, your conversation partner(s) could have the same problems, as described in the previous point. But they may also be using the speakerphone function. The microphone on the phone is then often very sensitive so that the person can also set the phone down and still be heard. But this in turn means that you hear more of the room, and thus also more echo, more loudly.

## 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/allgemeine-losungen-beim-telefonieren-mit-sipgate/wie-kann-ich-probleme-wie-stoergeraeusche-hall-und-schlechte-sprachqualitaet-beh.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.
