Voice over WiFi is finally here in India. Seeing VoWiFi on my Airtel connection. At least a dozen years too late, but better late than never. This will solve phone signal issues in basements and remote areas, and enable so many use cases.

This is phenomenally better than VoIP apps, because both ends don't need an intelligent terminal, data connectivity, or subscription to the same app. One end can be a simple landline or feature phone. After HD calling, this is another edge that VoIP apps just lost.

The ideal scenario would be telcos giving out VoIP phone connections (SIP accounts and trunks). Nevertheless, VoWiFi solves a lot of pain points.
