Firstly, the message “call cannot be completed as dialed” is generated by the CUCM, not the provider. This message is played when the CUCM cannot handle the call. You mentioned that both working and non-working extensions have the same CSS. Could you please check the CSS assigned at the phone level for both these extensions? I’m asking this because if there’s a CSS at the extension level and a different one at the phone level, the phone CSS takes precedence.
Have you debugged the gateway? If the calls are functioning when you change the gateway, then the issue lies with the gateway. Debugging the call will provide more information.
Could you share the debugs of the gateway? If it’s a SIP gateway, use “debug CCSIP messages”. If it’s a PRI, use “debug isdn q931”. also share, “debug voice ccapi inout”.

It might be worthwhile to examine a working phone/target number and a non-working phone/target number using the Dialed Number Analyzer. Saving both outputs and comparing them might show what the difference is.
I agree with @Nithin Eluvathingal - The first thing I'd check is that both the Line CSS and Device CSS are the same on the non-working phone as the working phone.
If they are the same, then the next step would be to collect a debug on the gateway/CUBE for a working and non-working call to see if the non-working call is reaching the gateway. If it is not then the issue is 100% a CUCM issue. If it is reaching the gateway, then it is likely a gateway issue.
