Our engineers can provide hourly support to work with your 3rd party hardware and configure it for you.
In terms of VoIP a codec is a choice of how your call is compressed into digital form and decompressed back into audio. All VoIP calls use some codec or another. The reason there are many is because VoIP can be used in many ways. For instance if you are in another country using a very low bandwidth connection, you can choose to use a codec with lower quality audio to make your calls while using a poor connection. When you have a strong connection you may choose to use a high quality audio codec for more call clarity. Experiment and choose the codecs that work best for you and your calling environments.
Most of the time this trouble is caused from the app. or the phone itself. It could also be a headphones or headset connection. It is best to check these things first. Make sure any headset is connected properly. Restart the app. you are using to call with. And, finally if the trouble is still there try restarting your phone.
You may be moving outside of your wifi network coverage. When this happens your phone will not be able to connect through wifi and will try to connect by your mobile data 3g/4g connection. There is no need to be concerned, just be aware that your phone will behave this way when entering and exiting wifi network areas. Otherwise, you may want to reset the application or phone device if behavior continues oddly or submit a trouble ticket if this happens on multiple devices and you feel it is a service issue.
