Cube ACR Not Recording Calls — What to Do and What to Use Instead

TL;DR: First check permissions, the connector, the audio source, battery optimisation and updates. If your team relies on Cube ACR, recurring problems may mean that an app running on each person's phone is not reliable enough for your business.

Problem: only one side is recorded

This is usually an audio-source issue. Android limits access to call audio, so recording apps test different modes such as voice call, voice recognition, microphone, or software source.

Try:

1. Update Cube ACR.
2. Enable Cube ACR App Connector in your phone's Accessibility settings.
3. Test other recording audio sources.
4. Make a test call without Bluetooth headphones.
5. Check microphone and phone permissions.

Problems after an Android update

System updates can disable permissions, change how Accessibility features work or restrict background activity. Re-enable permissions, disable battery optimisation for Cube, restart the phone, check the connector, and test again.

Problem: no recording file

Check that automatic recording is enabled, the number is not excluded from recording, there is space available, the recording folder exists and the app is not being put to sleep.

iPhone issue

Cube on iPhone works differently. According to its App Store listing (checked 19 October 2026), your carrier must support three-way calls: you add the recording service's number and merge the calls. If the carrier does not support call merging, or the steps are not followed, recording will fail. Adding Heilo to a call with Heilo Select uses the same mechanism, and the notes land in your team's dashboard.

When to stop fixing Cube

For private use, testing settings can be worth it. For business, count the cost:

• missed recordings,
• unusable files,
• manual MP3 sharing,
• missed calls with no message,
• recordings stuck on personal phones.

If calls bring in revenue, your recording process cannot depend on a single Accessibility setting.

Alternatives

Built-in phone recording — good when available on one device. Our guide on how to record phone calls covers the built-in options on Android and iPhone.

Another recording app — may help, but faces similar system limits.

A business-number system — best when you need transcription, shared access, contact history, and missed-call capture. For a point-by-point comparison, see Cube ACR vs Heilo.

Current troubleshooting from the publisher

Cube ACR's official FAQ, reviewed on 19 October 2026, explains how recording depends on your device, Android version, connector and audio source. For Android 10–14 it recommends the “voice recognition (software)” audio source, “force in-communication mode” in the same menu, and Cube ACR App Connector switched on in Accessibility settings; for Android 6–9 it names “voice call (software)”, and for Android 9 also “voice communication (software)”; if the Android 10–14 settings do not help, it suggests trying “voice call (software)”. The publisher also says its workaround for Android 9–14 does not work for calls through Bluetooth or a headset, and that not every device can record VoIP calls because of hardware limits that software cannot fix. The FAQ says nothing about newer Android versions. These recommendations come from the publisher; we have not tested every handset.

Note your device model, OS version and app version. Change one setting at a time, then check that both voices can be heard in a test recording. Download any required helper app only from the channels listed by the publisher, and review the permissions it requests. Installing it does not guarantee that recording will work. Test Bluetooth, ordinary phone calls and calls made through any other apps you need separately. Our guide to recording WhatsApp, Messenger and Telegram calls covers the limits of app calls.

An alternative must capture the call you actually need

With missed-call forwarding, Heilo records the message a caller leaves; it does not replace Cube for a conversation you answer. To capture calls you answer, add Heilo to a supported conference call with Heilo Select (Heilo records from the moment it joins), or use a Heilo business number with Heilo Line, the default for regular recording. Each rep gets their own +48 number, and calls through it are recorded automatically; by default a new number plays a recording notice to the other person. After each call you get a transcript, a summary, suggested tasks and notes from the call coach on what went well and what to improve. Outbound calls start in the dashboard with “Call via Heilo” (+48 numbers only). Once you set up an integration, the API, signed webhooks, Zapier or Make send the results to your own CRM.

If SMS notifications are configured, they provide context and a link; the full transcript is available in Heilo. Before you choose a plan, check with your carrier that it supports conference calling, which Heilo Select requires. Plans and prices are on the pricing page.

Conclusion

Cube ACR can be a good tool for personal use. If you constantly need to fix its settings, the problem goes beyond the software: your company needs call records that the team can find, read and use to assign follow-up work.
