DID Outgoing display issue

I did a fresh install of the MTE version 8.0.1.1, created a tenant in which i set the External Caller ID to "1111" (as an example)...
Under the tenant i created an extension (1112) and set a DID to 1112...
If i call from external to 1112, the extension rings, no issues...
If i call from the extension to external, the number being displayed is 1111 not 1112...
Under the extension > Advanced Settings i have tried setting the External Caller ID Number to:
Use Assigned Default
Use DID as Caller ID
Enter (and i enter 1112)

All external calls will appear to be 1111...

Tried different tenants and different extensions, all with the same result...

Any suggesions???
