Voice Call Continuity

What Does Voice Call Continuity Mean?

Voice call continuity (VCC) describes how a voice call persists even when being switched from one circuit to another.


The major goal of voice call continuity (VCC) is to provide call consistency to the end users as calls are continuously moving between different networks and vendor technologies. VCC enables the user’s device to select a required network automatically, providing a reliable relationship between the user’s device and network.

Techopedia Explains Voice Call Continuity

In telecommunications, voice calls are not limited to only one network but rather can move between multiple networks. These networks include circuit-switched networks and packet-switched (radio) domains. In other words, a voice call should be able to persist even when the call switches from one technology to another.

Many Internet applications are available via mobile devices, such as VoIP (voice over Internet Protocol). VCC specifications allow incoming/outgoing calls from any circuit-switched network to be carried out through IP.

VCC supports the following:
1. Wi-Fi
2. Global System for Mobile Communications (GSM)
3. Worldwide Interoperability for Microwave Acces (WiMax)
4. Code division multiple access (CDMA)
