What internet calls are
Internet calls carry voice as packets over Wi-Fi, mobile data or another IP connection instead of a traditional fixed telephone path. See also the glossary and FAQ.

Internet calls with Narayana CYou
Understand internet calls, Wi-Fi calling quality, mobile internet, international calls and practical VoIP troubleshooting.
How calls through internet work
The app or device captures audio, encodes it with a codec, sends signaling to establish the call and then exchanges RTP media packets during the conversation.
SIP vs app calling
SIP is an open signaling protocol that can work across many clients. App calling may hide those details, which is simpler but less flexible for advanced users. See also the glossary and FAQ.
Voice quality factors
Bandwidth, latency, jitter, packet loss, microphone quality, codec choice and device load all affect how natural the call sounds.
Wi-Fi vs mobile internet
Wi-Fi can be excellent when the router is stable. Mobile data is useful while moving, but coverage changes can introduce short interruptions. See also the glossary and FAQ.
International calls
Internet calling can make international contact easier, but correct number format, prepaid balance and destination rules still matter.
Troubleshooting
If calls fail, check login status, microphone permissions, balance, number format, firewall restrictions and whether another network performs better. See also the glossary and FAQ.
