What is Handoff in VoIP?

Handoff in VoIP is the seamless transfer of an active call from one network or device to another without dropping the call. It’s commonly used in mobile VoIP scenarios where calls transition between Wi-Fi and cellular networks or when switching between softphones, desk phones, and mobile apps. Handoff ensures that communication continues smoothly when a user moves between locations or devices. VoIP platforms supporting handoff use protocols like SIP for call signaling and maintain session continuity during the transfer. This is very helpful for remote workers and field employees who rely on consistent connectivity during business calls. Handoff enhances mobility, reduces dropped calls, and improves overall call reliability.
