# Robotic or choppy sound

Monema App

SIP telephony or internet telephony is very susceptible to changes in the network. These can be due to various causes, the most common being:

### **If you are using a laptop or PC connected via Wi-Fi.**

Make sure you are not too far from the router and that there are not too many obstacles between you and the router. Mirrors in particular can cause interference.

-   We recommend connecting via a network cable whenever possible.

### High bandwidth usage

Cloud storage services, backups, downloading large files, video streaming, etc. High use of network resources significantly affects the quality of SIP calls.

-   If you use Wi-Fi in these cases, we recommend using a network cable to get the highest possible bandwidth and improve network stability.
-   Limit the bandwidth of applications. Many applications allow you to limit upload and download bandwidth. Try limiting it to leave room for SIP calls.

### Audio device

Ensure you are using the correct recording device.

Check under Account > Audio Settings that you have assigned the correct audio device for each of the following categories:

-   Recording device (microphone).
-   Playback device, which you will use to hear the caller/person you are calling (speakers/headphones).
-   Device for call notification when you receive a call (speakers/headphones).

### Problem with the recording device

Sometimes the microphone you are using may be of poor quality or pick up too much background noise.

-   You can record a test with any audio recording app and check if the quality is satisfactory. If not, try another device with better quality.

### Perform an “echo” test

This test consists of pressing \*9 and calling. When you speak, you should hear yourself with a slight delay. This verifies that the audio is being sent to Monema's servers and returned to you without any problems.

### The problem could be with the person you are talking to

Check patterns such as whether it only happens with one specific person or whether it happens with everyone.

-   Coverage issues with your call. If you are in an area with poor coverage, this behavior may be normal.

### Others

If you have not found a solution in the previous steps, please send us an email to [info@monema.com](mailto:info@monema.com) with the date/time of the call and, if possible, the number of the caller or the person called so that we can analyze the quality of the call and the possible causes.
