The 3131, a voice service that allows users to find out the number of the last unanswered call, has long been the go-to for landline subscribers. With the massive shift to internet boxes and total unbundling, this service operates unevenly depending on the operators. Some subscribers report a constant busy tone, while others experience complete silence. The question of replacing the 3131 thus arises for those who want to keep track of their incoming calls.
Why the 3131 no longer works on certain landlines
The 3131 was originally designed for the public switched telephone network (PSTN), managed by France Télécom and then Orange. Its operation relied on a centralized infrastructure that identified the last unanswered incoming call and relayed it vocally.

With the widespread adoption of internet boxes, landline telephony now transits through VoIP (voice over IP). Each operator manages its own implementation of the service. Free, for example, offered a functional 3131 on its unbundled lines, but subscribers have been reporting recurring outages for several years, with a busy tone and no clear explanation. On specialized forums like those of Univers Freebox, user feedback varies on this point: some users get a response, while others never do.

The underlying problem is structural. The 3131 has never been standardized among VoIP operators. Each maintains it (or not) according to its technical priorities, without a regulatory obligation to provide it. This lack of framework explains the disparity in experiences.
Call log on internet boxes: the solution operator by operator
The true successor to the 3131 is not a number to dial. It is the call log integrated into the internet box, accessible from the administration interface or the connected phone’s screen.
Free and Freebox OS
Free has integrated a detailed call log in Freebox OS (starting from version 4) that can be accessed via a browser. By going to the Telephony section of the local interface, subscribers can find the list of incoming, outgoing, and missed calls, with the calling number when it is not hidden. This log operates independently of the 3131 and serves as a more reliable alternative for subscribers facing repeated failures of the voice service.
Orange and recent Liveboxes
Orange has standardized its call tracking services on recent Liveboxes by integrating a call log accessible on the HD phone screen or through the box’s administration interface. This log is valid even in case of a 3131 failure or when the number is not displayed on the handset. For Orange subscribers, this is now the most direct method to consult the history of received calls.
SFR and the customer area
SFR has generalized access to the fixed call history via its online customer area, in the Telephony section. Incoming and outgoing calls are listed there, allowing users to find a number without relying on a voice service. The SFR customer area replaces the 3131 for lines managed by boxes.
Mobile applications and call history on Android smartphones
The question of replacing the 3131 arises differently for mobile phone users. On an Android smartphone, Google’s native Phone app keeps a complete history of received, missed, and outgoing calls. Access is done by opening the “Recent” tab of the app.
To go further, third-party applications like “Call History of Any Number” (available on Google Play) offer sorting, filtering by number, and call log backup features. These tools can be useful for retrieving an old call that the native log may have purged.
Here are a few points to check before installing a call management application:
- The permissions requested: a legitimate application only needs access to the call log and contacts, not to SMS or full storage
- The privacy policy: some free applications monetize call data, which raises an obvious privacy issue
- Compatibility with your version of Android: access functions to the call log have evolved between Android 6 and recent versions, with some restrictions limiting what third-party applications can read
Current limitations of tracking received calls in France
None of the solutions described replicate the exact functioning of the 3131. The original voice service allowed users to immediately call back the last caller with a single touch. The call logs of boxes and smartphones provide the information, but one-touch automatic redial no longer exists in most cases.
The presentation of the number remains another obstacle. When the caller hides their number or the operator does not correctly transmit the identifier, neither the 3131 nor the box log can display the information. This issue, regularly reported on Free and Orange forums, relates to the transmission chain between operators and not to the subscriber’s terminal.
It should also be noted that the call logs of boxes have limited storage capacity. On some models, only the most recent calls are retained. For long-term tracking, regular backups or export of the log are necessary when this function is available.
The landscape has changed: the answer to “which number called me” no longer goes through a centralized voice service but through a combination of digital tools specific to each operator and each terminal. The fragmentation complicates the process, but the information available is often more complete than with the old 3131, provided you know where to look.
