Grandstream Wave is a free, carrier‑grade SIP softphone application that transforms your smartphone or tablet into a fully functional IP phone. It's the perfect companion for Grandstream IP PBX systems, enabling mobility without sacrificing call quality or business features. Whether you're at home, on a business trip, or walking through the warehouse, Wave keeps you connected to your office extension seamlessly.

Unmatched Flexibility: Wave supports up to 6 independent SIP accounts with multiple lines. That means you can have your desk extension, a department hotline, and even personal VoIP accounts all on the same device. The app’s intuitive interface mirrors a physical phone — complete with a dial pad, call logs, and contact management — making it instantly familiar to anyone who has used a Grandstream desk phone.

Designed for Business: Wave is not just a dialler. It offers features you typically find on enterprise IP phones: transfer (blind and attended), 6‑way ad‑hoc conferencing, call hold, and DND. Virtual BLF keys let you monitor the presence of colleagues and speed dial with a single tap. LDAP and Active Directory integration ensures you always have access to the corporate phonebook.

Zero‑Touch for IT: Administrators love Wave because it can be provisioned in seconds. Users with a Grandstream UCM can generate a QR code; the user scans it with the Wave app, and all SIP credentials, server settings, and feature keys are auto‑configured. For larger deployments, GDMS (Grandstream Device Management System) offers cloud‑based provisioning and management.

Cost‑Effective Mobility: Rather than purchasing expensive cordless handsets, many businesses equip staff with Wave on their existing smartphones. It runs on Wi‑Fi or mobile data (3G/4G) with excellent call quality, thanks to Opus and G.722 audio codecs and advanced jitter buffer technology. It's an ideal solution for remote workers, sales teams, and warehouse staff who need to stay connected while on the move.

Completely Free: Grandstream Wave is free to download and use. There are no subscription fees or in‑app purchases. Simply install it, connect it to your SIP server, and you have a powerful softphone that can replace a physical desk phone entirely.
