What technology does INX use?
INX uses a standards-based voice-over-IP (VoIP) protocol called SIP (Session Initiation Protocol) with software that allows INX endpoints to work on packet switched IP networks. INX also uses advanced voice compression protocols (G.729) to maximize voice quality and minimize latency over public IP networks. In many instances, INX’s voice quality often exceeds that available on PSTN or mobile phone networks. Lastly, we use gateways to connected to the public telephone network so that you can make and receive calls for any wireline or mobile phone in the world.
