Room Phone app for iPhone and iPad

Room Phone allows you to easily control conference room phone systems with your iOS device. You can add multiple conference rooms, quickly switch between them, dial contacts from your address book, and manage in-call features like hold, mute, and call volume. Multiple users can control the phone system at once, with changes to the current call status reflected on other users devices. No more manually typing numbers into a confusing control system with speed dial presets that are out of date, Room Phone lets you dial directly from your own phone using your own contacts.

Phone System Support:
Currently Room Phone supports a range of ClearOne audio processors and BiAmp products with the Audia VOIP2 card installed. For ClearOne systems, you will need the device’s IP address, username, and password. For BiAmp products, you will need the device’s VoIP Block ID, Transmit Block ID, Receive Block ID, Device ID, and Channel.
