Why the caller does not hear on ARMTEL DWEx Telephone?
- KKathleen GonzalezAug 16, 2025
If the caller or called subscriber cannot be heard, there might be two reasons. First, the speaker volume (microphone or handset sensitivity) could be set to the minimum; in this case, adjust the volume using the special controller. Second, the cable of the speaker (microphone, handset) may not be connected properly or could be defective; check the connection and ensure the integrity of the speaker (microphone, handset) cable.
