When to use VoLTE vs. an OTT voice app
In a previous article, we discussed voice over LTE (VoLTE) and its implications for the enterprise VoIP phone system. All voice traffic over the LTE (also known as 4G mobile) network is packetized and conforms to modern VoIP standards, making it the first mobile telephony standard to completely circumvent the traditional circuit-switched telephony infrastructure.
In many ways, VoLTE sounds a lot like over-the-top (OTT) voice applications that leverage the same protocols for voice. In this article, we look at what OTT voice apps are, what VoLTE is in relation to OTT, and the benefits of using one, the other or both over an LTE network.
