Your service.
Your workspace.

Open directly to Dialer login. A small OTP link takes you to the separate OTP login. Account creation, email verification and initial signup stay on the website.

What you can try today

Email and Google login, live dashboard and recent calls, health metrics, expandable call recordings, CRM contacts, text conversations, voicemail audio and greetings, password settings, recordings, monthly performance graphs, team and support cases with optional screenshots. OTP has country-first service search, 12 featured offers and a dedicated activation confirmation page. Message removal hides customer inbox entries while retaining server records under the existing policy. Number requests include a package estimate. One support case may stay active at a time. OTP includes catalog, quotes, orders, codes, wallet and local payment submissions. Incoming SIP calls, ringing, full-screen wake, earpiece, speaker and microphone mute have been checked on an Android 12 phone, including after Android closes the background app process.

Updates inside the app

When a newer version is available, updating is required after active work finishes. Calls, waiting OTP orders, audio playback, forms and requests defer the prompt. Direct installations download inside Kandrex and verify the APK before Android’s install confirmation. Settings → Updates also shows update status. The Play release variant integrates Google Play updates; Play track validation is pending.

Before public launch

Native calling now includes outgoing calls, hold, keypad and recording controls. SIP transfer and three-person calling support external US/Canada destinations on metered calls. These new controls await device acceptance testing. SDK AI call acceptance, on-network transfer/add-person, message attachments and production Play signing remain unverified or unavailable. Text messaging uses your existing account permissions and SMS allowance.

v0.12.3 · Android 8.0+ · Early access

Version 0.12.3 restores saved sessions automatically, retries temporary read failures quietly, and signs out after seven days without user activity. It retains native outgoing calls, hold/resume, an in-call keypad, recording, and metered SIP transfer/add-person controls for external US/Canada numbers. The new controls await owner acceptance testing. It retains native incoming-call ringing and full-screen wake while locked or backgrounded, including after Android closes the app process. Earpiece, speaker and microphone mute were verified on an Android 12 phone. It retains automatic crypto payment invoices with QR codes, copy buttons, and a one-hour payment window. Closing the prompt keeps server payment monitoring active. It includes private account notifications for messages, voicemail, missed calls, OTP codes and refunds, payment decisions and support replies. It keeps the update prompt hidden while Android installs, defers required updates during calls and OTP activity, and displays SMS codes and international numbers with copy buttons. Android asks you to approve installation. Install over your existing app to keep your account data.
