BoxPhone PRO turns your iPhone's phone into a power tool for anyone who dials more than a plain number: PBX and switchboard users, road warriors, tinkerers and the phone-curious. Do more with your phone. PRO DIALING PROFILES Save prefix + pause + number + suffix as reusable profiles (office PBX, home VoIP, calling cards…). Add automatic pauses, a manual "wait" step for IVR menus, and per-call caller-ID suppression. Switch the active profile in a tap, override it for a single contact, or dial with no profile at all. FAST CALL, EVERYWHERE Put your favorites one tap away — Home Screen and Lock Screen widgets, StandBy, a Control Center control, the Action Button, Siri and Shortcuts. Every shortcut dials through your PBX profile, not just a raw number. For contacts with more than one number, pick exactly which one to use. A KEYPAD THAT FEELS RIGHT A clean dialer with real DTMF key tones, favorites and full Contacts integration — fast, focused and easy on the eyes in a modern dark design. TONE TOOLS A professional multi-frequency tone generator (DTMF, MF R1, call-progress) and a live DTMF decoder that reads tones straight from the microphone. Perfect for testing IVRs, PBX extensions and phone systems. PHREAK MUSEUM A nostalgic, educational corner with the historic signaling tones that shaped telecom — 2600 Hz, blue box and red box. For history and curiosity only: these tones do nothing on modern networks. PRIVACY FIRST No ads. No tracking. No account. Your contacts and favorites stay on your device. Do more with your phone — with BoxPhone PRO.

PrefixPlus allows you to add the prefix number to phone numbers in Contacts at once. Phone numbers with the prefix number will not be replaced but added to contacts. For example, if you set the number "+81" and the label "Call(JP)", contacts will be updated as follows. [Before update] Home: 03-1234-5678 Mobile: 090-1234-5678 [After update] Home: 03-1234-5678 Mobile: 090-1234-5678 Call(JP) Home: +81-3-1234-5678 Call(JP) Mobile: +81-90-1234-5678 (Caution) Be sure to back up contacts as security against accidents. For example, if you back up to iCloud, you can restore contacts at some point in the past. Please note that you can add prefix numbers to contacts synchronized with local, iCloud, Gmail only.
