Aiphone Intercom Has One-Way Audio or No Audio
Audio Fault
Summary
Follow the four stages below to diagnose an Aiphone call has one-way, intermittent or no audio without losing evidence, configuration or device ownership.
Applies to
- Aiphone indoor stations and supported apps
- IP and wired Aiphone intercoms
Difficulty and time
Difficulty: Moderate
Estimated time: 15 to 40 minutes
What you will need
- The exact model and current firmware or app version
- Administrator access where authorised
- A photo or screenshot of the current status
- One controlled test case and its exact time
What this guide covers
- Preserve and reproduce the fault
- Open the correct diagnostic screen
- Correct the proven cause
- Verify and document the result
Use this page when an Aiphone call has one-way, intermittent or no audio. It includes the menu or screen to look for, the status that matters and a repeatable proof test.
Exact labels can differ between recorder, controller, app and firmware versions. If the named screen is not present, do not guess at destructive options; note the model and current version for support.
Before you start
Protect the current system and record a baseline before changing anything.
- Write down the exact symptom: one party cannot hear, audio cuts out, or normal speech behaves like push-to-talk.
- Photograph the current status, error text, wiring or timeline as applicable.
- Record the last known working time and anything changed immediately before the fault.
- Record current audio/volume settings and exact failed direction before changes.
Do not assume every one-way-audio symptom is cabling
Some models use privacy or press-to-talk behaviour. Confirm the operating mode before rewiring or replacing equipment.
If the required option is missing or the result does not match this guide, stop and identify the exact model before continuing.
What usually causes this
- Call or receive volume is low
- PTT/privacy mode is active
- One microphone/speaker endpoint failed
- Network or wiring path is unstable
Step 1: Preserve the current state and reproduce the fault
Begin with a repeatable baseline so you know whether a later change genuinely helped.
- Reproduce the problem once and record: one party cannot hear, audio cuts out, or normal speech behaves like push-to-talk.
- Note whether every device or user is affected, or only one.
- Compare one working path with the failing path if a comparison exists.
- Record current audio/volume settings and exact failed direction before changes.
Step 2: Open the correct screen and inspect the evidence
The primary diagnostic location is Indoor station/app > Settings > Volume/Call Settings, then system configuration > Station/Audio settings. Do not change anything until the displayed state is recorded.
- Open Indoor station/app > Settings > Volume/Call Settings, then system configuration > Station/Audio settings. Menu wording can vary by model and firmware; use the nearest equivalent label.
- Identify which direction fails: visitor-to-resident or resident-to-visitor.
- Test a second station/app to isolate one endpoint.
- Check call, receive and microphone volume plus any privacy or press-to-talk mode.
Step 3: Correct only the cause you proved
Use the matching correction below. Make one change, save it, then repeat the same test.
- Raise the relevant call/receive volume gradually and retest.
- Disable unintended privacy/mute settings or follow the model-specific PTT operating method.
- Verify station assignment and network quality for IP systems.
- For wired audio faults, inspect cabling/terminations using the model wiring diagram.
Step 4: Verify, monitor and document the handover
A saved setting is not proof. Test the real outcome locally first, then test any app, cloud or client path separately.
- Place three calls and speak in both directions.
- Test at normal speaking distance without covering microphones.
- Compare station and app calls if both are supported.
- Confirm unlock tones and other audio cues remain at a sensible level.
Controlled support test
Situation: The reported symptom was: one party cannot hear, audio cuts out, or normal speech behaves like push-to-talk.
Solution used: The current state was recorded in Indoor station/app > Settings > Volume/Call Settings, then system configuration > Station/Audio settings, one matching correction was made, and the same test was repeated.
Why this was chosen: This separated the proven cause from unrelated settings.
Installation notes: The final screenshot and test time were saved with the handover record.

Common mistakes
- Changing several settings before repeating the original test.
- Using a factory reset, initialise or format option as an early troubleshooting step.
- Treating an app symptom as proof that the local hardware or recording has failed.
- Failing to record the model, version, exact error and test time before escalation.
- Assuming similar-looking models use identical menus or features.
Troubleshooting table
| Symptom | What to check | What to do next |
|---|---|---|
| one party cannot hear, audio cuts out, or normal speech behaves like push-to-talk | volume/mute setting, PTT/privacy mode, failed endpoint, station mapping, network loss or wiring fault | Open the named diagnostic screen, record the displayed state and use the matching correction above. |
| The named menu is not visible | Different firmware, permissions or model capability | Do not substitute a destructive menu. Capture the model and version and use its official manual. |
| The change saves but the fault remains | The selected cause was not the root cause | Undo the change if appropriate, return to the baseline and compare the failing path with a working one. |
| Local test works but app or client test fails | Account, permission, cloud or remote-network path | Keep the proven local configuration and diagnose the remote path separately. |
| Problem returns later | Intermittent power, cable, storage, network or schedule condition | Record the new failure time and status; correlate it with logs, events and the last known working interval. |
When to contact support
Contact SecurityWholesalers support when the failed direction follows one station after volume/mode, endpoint comparison and network/wiring checks.
Send the order number if available, exact model, firmware or app version, screenshot of Indoor station/app > Settings > Volume/Call Settings, then system configuration > Station/Audio settings, the failure time, and the result of the local proof test.

Frequently asked questions
-
Where should I click first for Aiphone one way audio?
Start at Indoor station/app > Settings > Volume/Call Settings, then system configuration > Station/Audio settings. Record the existing state before changing it because labels and available options can vary by model and firmware.
-
What should I look for on that screen?
Look for call/receive volume, mute/privacy/PTT mode, station identity and which direction fails.
-
What must I avoid changing during the first check?
Some models use privacy or press-to-talk behaviour. Confirm the operating mode before rewiring or replacing equipment.
-
How do I prove the correction worked?
Complete three normal calls with intelligible speech both ways and no need for undocumented workarounds.
-
Why might my menu names look different?
Recorder, controller, camera, app and firmware releases can use different labels. Use the closest equivalent only when its function is clear; otherwise record the model and version for support.
-
Should I factory-reset the device?
Not as an early step. A reset may erase users, network settings, recording configuration, licences or cloud ownership. Back up the configuration and confirm the recovery plan first.
-
What should I send technical support?
Send the exact model and version, screenshot of Indoor station/app > Settings > Volume/Call Settings, then system configuration > Station/Audio settings, exact error text, failure time, what changed before the fault and the result of the controlled local test.
-
Can configuration changes recover data or events that were never recorded?
No. A correction can restore future operation, but it cannot recreate footage, alarm events or access transactions that were never stored.
