SIP/VoIP softphone with caller greeting, hold music and call recording.
Read full description
Callwise turns the VoIP account you already have into a calm, reliable phone line on your Android phone.
Add the account from your VoIP provider or office phone system (SIP user name, password and server), then make and receive calls like on a regular phone, with the lock screen, Bluetooth and your contacts working the way you expect.
WHY CALLWISE • Greet every caller: answer with your own welcome message, then callers hear hold music until you tap “Take the call”. Record the greeting with your voice or use any audio file. • Never miss a call: calls ring like normal phone calls, even when your phone is locked and the app is closed. • Works with your provider: any standard SIP account from a VoIP provider, hosted PBX or office phone system. • Simple and calm: a clean dialer, recents and contacts. Technical settings stay under Advanced, out of your way. • Private by design: no ads, no tracking, no sign-up. Your password is stored encrypted on your phone, and your calls, contacts and recordings stay with you. • Light and dark mode, in English, Turkish and Spanish.
FEATURES • Incoming calls full screen, on the lock screen • Receive calls while the app is closed (Pro) • Call recording, with one tap or automatic (Pro) • Greeting: callers hear your message and hold music until you take the call (Pro) • Speaker, Bluetooth headsets and car kits, mute, hold and keypad tones • Call history with a missed-call filter, favourites from your address book • Advanced: UDP, TCP and TLS, SRTP media encryption, STUN / TURN, outbound proxy, custom port • Diagnostics: connection health and a report you can share with your provider
FREE TRIAL AND PRO Every feature is free for 14 days, no payment details needed. After that, Callwise stays free to use while the app is open. Callwise Pro keeps your line ready in the background and unlocks call recording and the greeting: monthly, yearly, or once for a lifetime.
GOOD TO KNOW • Callwise is a softphone: you need a SIP account from a VoIP provider or your company. Callwise does not sell phone numbers or call minutes. • Callwise is not a replacement for your phone's regular calling. Use your phone's own dialer for emergency calls. • Call recording laws differ by country. Tell the other person when you record.
