Issues with calls not getting through

Sometimes, you may notice that certain calls are not getting through. This can happen for a number of reasons, including:

1. Issue with the tracking number provider or network

Certain calls never connect and don’t reach your destination. There may be an outage or technical problem on the tracking number provider’s network. Nimbata cannot deliver these calls if the number provider or underlying network isn’t processing the call properly. Contact Nimbata support to confirm if the provider is at fault.

Before concluding this is a provider issue, it’s recommended to confirm that the tracking number is correctly assigned to a call flow.

2. Tracking number not assigned to a call flow

Calls may be initiated but get dropped or declined before reaching your team. The tracking number is not assigned to any call flow, so Nimbata doesn’t know where to send the call. Assign the number to an existing call flow - or create a new call flow and assign it.

3. Call disposition statuses showing failures

Nimbata logs call disposition statuses that help diagnose why calls didn’t connect. These are useful for troubleshooting and for automation. For example:

• User Busy (network or recipient engaged)
• No User Response / No Answer (ringed but unanswered)
• Call Rejected
• Service Unavailable / Network Failure
• Invalid Number Format

4. No connected calls because no calls were placed

In some cases, the issue may simply be that no one has attempted to call the number yet. You set everything up correctly, numbers, call flows, analytics, but see zero calls. There simply haven’t been any incoming calls yet:

• Confirm your setup via Day 1 checklist.
• Look in Analytics > Visit Stats and verify the date range.
• Check Calls per channel.

Start by making sure that your tracking numbers are assigned to call flows.

If the issue isn’t explained by the points above, get in touch with us and include any relevant call logs or timestamps.
