Wi-Fi Calling Hosting

Reliable business calling where cellular can't reach.

Hosted Wi-Fi calling that turns any room with internet into a clean voice environment — basements, warehouses, metal buildings, rural sites, healthcare facilities.

The problem we solve

Modern business phones, even SIP softphones, depend on either rock-solid cellular signal or rock-solid Wi-Fi. Cellular fails in metal buildings, basements, healthcare facilities, and most of rural Iowa. Wi-Fi is everywhere — but raw Wi-Fi calling has packet-loss and codec problems that make business calls sound bad.

Greenway's hosted Wi-Fi calling service sits between your devices and the PSTN, handles codec negotiation, manages jitter buffers, and delivers carrier-grade audio over whatever Wi-Fi you have.

What's included

  • DID + extension assignment per user, with optional ring-group routing.
  • Standard SIP clients — works with Zoiper, Linphone, Bria, native iOS/Android softphones.
  • Codec negotiation for low-bandwidth connections (Opus, G.722, G.711 fallback).
  • Voicemail with email delivery.
  • SMS / MMS optional — business texting on the same number.
  • 911 with registered address for safety compliance.
  • Bring-your-own-Wi-Fi — no special access points or hardware required.

Who this is for

Healthcare facilities, warehouses, manufacturing floors, basement offices, rural businesses, and field-service crews who need a real phone number that rings reliably from anywhere with Wi-Fi.
