HD telephony in sipgate: the highest voice quality for VoIP calls – automatically included in all plans.
HD telephony enables the highest possible voice quality currently available for landline or VoIP calls and is automatically included in all sipgate plans.
The simple answer: clearer, fuller, and more natural. The technical background: Unlike conventional telephony, a wider frequency spectrum of the voice is transmitted. No additional bandwidth from your internet connection is required.
You do not need to make or adjust any settings in your sipgate account. If your hardware meets the requirements, you will automatically make calls in HD. To do this, you need HD-capable phones or end devices. In detail, this means that your VoIP phone must support the required codec (G722 and Opus), which can transmit speech in HD quality. Many phones already support exactly these codecs, but you may need to adjust the configuration of the end device.
A phone call naturally always goes both ways. If the person on the other end of the line does not have HD telephony, you will automatically make calls in normal voice quality. But many telephony and device providers have already switched to HD or are working on it. So it can be assumed that HD telephony will become the absolute standard in the near future – and with sipgate, you are already perfectly equipped for it now.
