Supported audio codecs

Our IP telephony service is compatible with the G711u, G711A, G729 and G723 audio codecs. However, we recommend using the G711u or G711a if you have an excellent Internet connection and use the G729 if you have low-speed internet. If you are going to use the service on a mobile phone or tablet via 3G, we recommend the G729 for good audio quality.
