If outside callers get a "the number you have dialled does not exist" message but your CloudTalk test calls connect fine, this guide will help you confirm the cause and get it resolved.

Symptoms
You might notice one or more of the following:
External callers hear "the number you have dialled does not exist" or a similar message
Callers from certain countries or mobile networks can't reach your number, while others can
Test calls placed from inside CloudTalk (or from another CloudTalk number) connect successfully
No changes were made to your CloudTalk account or number setup recently
Root Cause
When someone calls your CloudTalk number from a regular phone or mobile network, the call travels through the public telephone network before it ever reaches CloudTalk. The caller's carrier looks up your number in a global routing table to find out where to send the call.
If your number's routing information hasn't fully propagated to all carriers worldwide, or a specific carrier's routing table is out of date, that carrier won't know where to send the call. The result is an error like "number does not exist," even though your number is active and correctly configured inside CloudTalk.
This is a carrier-side routing issue, not a problem with your CloudTalk account or call flow.
Common situations where this occurs:
A number was recently provisioned or ported, and routing hasn't yet spread to all networks
A carrier's routing table has become stale or wasn't updated after a network change
Callers from a specific country or mobile network are affected while others reach you fine
Step-by-Step Solution
1. Make a test call from inside CloudTalk
If the call connects, your call flow and number configuration are working correctly, and the issue is upstream rather than in your account.
2. Test from different external networks
Try calling your CloudTalk number from a mobile network, a landline, and a number from a different country.
If some networks reach you and others don't, the issue is with specific carriers, not your setup.
3. Check if the failing calls appear in Call History
Go to Dashboard > Call History and look for the failed call attempts.
If the failing calls don't appear there at all, they aren't reaching CloudTalk. This confirms the problem is upstream, in the telephone network.
If the calls do appear in Call History, the issue is unlikely to be carrier routing, check your call flow and number settings instead.
If the issue persists
If you've confirmed the calls aren't appearing in Call History, contact CloudTalk Support with:
The CloudTalk number that's affected
The date and time of failed call attempts
The country and phone network the failing callers are dialling from, if known
CloudTalk will escalate to the carrier responsible for routing your number and ask them to verify it's correctly propagated across all originating networks.
Once the carrier identifies the routing gap, propagation updates typically take a few hours to a few days to reach all networks. CloudTalk Support will keep you updated on progress.
Additional tips
The more specific you can be about which callers are affected, the faster the carrier can identify the gap. If possible, ask affected callers which country they're calling from, whether they're on mobile or landline, and the name of their phone provider.
Carrier routing tables can change over time, so a number that's worked for months can become unreachable from certain networks without any change on your end. This is outside CloudTalk's direct control, but we can escalate to the carrier to get it corrected.
This issue can affect any number but is more common with certain countries or number ranges. Most numbers work without issue.
Test calls placed from within CloudTalk travel through CloudTalk's own network and bypass the public telephone network entirely, which is why they succeed even when external callers can't get through.
If uninterrupted external reachability is critical for your business, speak with your account manager about number options that may offer broader carrier coverage.
