Troubleshooting the Dialer app
Stuck some where or something is not working? You’ll find answers here
Below you can find some troubleshooting steps to resolve common problems we've seen with the Convolo Dialer.
Convolo Dialer restarts/reconnects frequently | #DialerCrashes #ReconnectingIssue
- Step 1: Close and Reopen the App. Most common case of Dialer showing the message below is after the computer’s sleep mode. In that case make sure to click “RESTART” or close/reopen the Dialer app.

- Step 2: Make sure that you have Dialer version above 0.1.342 or 0.1.415 (otherwise you can download the latest version here↗️)

- Step 3: Check your Network Speed For the best call clarity, the minimum speed for VoIP phone calls is between 90 kbps (kilobits per second) to 156 kbps at the other end of the VoIP speed spectrum. Please note that the recommended speeded by Convolo.ai is above 5 Mbps+ for Upload and Download. If you’re not sure what the speed of your connection is, you can use our quick and easy free speed test to see where you’re at. Whether the issue persists, try a different network or wifi and check whether the Dialer acts the same. After changing networks, remember to restart the application.
- Step 4: Ensure that no third-party applications such as Firewalls and Antivirus are interfering with the dialer app. We highly advise reconfiguring or enabling the Dialer app to work freely on such programs because they can severely impair the Dialer app's functionality.

Key Press Recognition (DTMF) doesn’t work | #NumberPressing
Possible reasons why DTMF is not captured correctly
Handset Issues: The handset is not sending the DTMF tones correctly over the telephony lines. This could be because of the settings in the handset, manufacturing defect, speaker/earphone mode, etc.
Carrier Issues: One or more carriers involved during the transmission of DTMF tones fail to transmit it properly (This could be due to a combination of the handset, operators, location/cell towers involved).
Environmental Factors: Any factor which can cause sound (DTMF tone) to be altered or lost, such as background noise, poor reception, poor audio quality, etc. can make it difficult to distinguish the DTMF tones, or can also lead to duplicate tones being detected (if a noise chops a single DTMF sound into two parts).
User Behavior: Problems might arise if a user provides DTMF key inputs in mute or speaker mode. It may also be because the user presses the keys too quickly for the DTMF to be interpreted.
Solution
1. Dial one of the following numbers. You should hear a voice command.
Phone number for test | Country to call from |
US/CA & Global | |
Scandinavia | |
UAE |
2. After the voice command, please press numbers 1-7. You should then hear a voice answer. If this works, that means the outgoing DTMF is working for you ✅
3. Then press 8 or 9. The call should stop, but you will receive a callback to the number you called in a few seconds.
4. Then again, after the voice command, please press any number, and you should hear a voice answer. If this works, that means the incoming DTMF is working for you ✅
Incoming and outgoing DTMF may be independent, so it makes sense to test both.
If one of the tests fails, or you still have DTMF issues, please get in touch with support@convolo.ai (providing specific examples is highly appreciated to solve the issue quickly).
