Common Errors in VoIP Calls on SprintHub: Causes and Solutions
When using the VoIP calls feature in SprintHub, some error messages may appear during the dialing process. These messages are provided by the VoIP carrier connected to the platform and are meant to indicate failures in attempting to complete the call. See below the main errors and how to resolve them:
⚠️ 1. “The number was not found to complete the call”
What does it mean?
This error occurs when the dialed phone number was not located by the carrier, that is, the call could not be routed because:
The number is entered incorrectly.
There is a missing digit (area code, prefix, or final digit).
The number no longer exists.
✅ How to resolve?
Check that the number is complete and includes all digits.
Confirm that the area code is correct.
Avoid copying numbers with spaces or special characters.
Try calling another number to test your VoIP connection.
⚠️ 2. “The dialed number is temporarily unavailable”
What does it mean?
This message indicates that the called number could not be completed at that time, because:
It is in an active call (busy).
It is turned off or out of coverage area.
It is temporarily inactive.
✅ How to resolve?
Wait a few minutes and try again.
Try an alternative contact (WhatsApp, email).
If the number belongs to a recurring lead or customer, notify your sales team.
⚠️3 - "Unable to place the call"
The red alert "Unable to place the call" on VoIP can represent a series of problems, failures, and incorrect configurations; follow the next steps to find where the issue is:
Insufficient account balance. Open your VoxImplant panel or other service and check if you have enough to complete calls. If the balance is low, purchase credits;
Queue configuration. If possible check the users and the queue flow, make adjustments, if it persists reset and try reconfiguring the queue;
Problem with the audio device: Before starting the call check audio devices such as microphone or speakers;
Check if the contracted VoIP service has a stable connection; if the problems above persist, reload the browser tab, wait a moment and try the call again;
Technical Support
If after reviewing the numbers the error persists, contact our support team to check:
The connection with your SIP provider.
The VoIP credit status.
If the number is active for calls on the carrier's network.
SprintHub continues to evolve to ensure a smooth, secure calling experience connected to your sales process.
