Grandstream Wave for iPhone

Turn your iPhone into a business-grade softphone

Grandstream Wave lets you use your iPhone as a full-function softphone when paired with a Grandstream UCM63XX series IP PBX. Install the app and register an extension on the UCM63XX platform to place and receive calls, host or join meetings, and stay connected while away from the office.

Core capabilities

• Register and manage UCM63XX extensions directly from your iPhone
• Place high-quality audio and video calls over the IP network
• Schedule meetings and join conference sessions without logging in
• Dial internal extensions, PSTN landlines, or mobile numbers as needed
• Create and participate in collaborative meetings from the app

Benefits for mobile teams

• Use the same extension and presence whether you’re at your desk or on the move, improving continuity and availability
• Reduce travel and centralize collaboration by joining meetings from anywhere
• Maintain call quality and reliability for voice and video communications
• Increase productivity by handling calls, transfers, and conference joins from a single app
• Support enterprise telephony features while minimizing hardware needs

Alternative option to consider

If you’re looking for a different solution for group viewing or casual meetups, Rave Watch Party (Free) is a recommended alternative that focuses on shared media experiences rather than corporate PBX integration.
