Calling Line Identifiers (CLI) can be used in conjunction with a purchased DID (Direct Inward Dialling service) from the Sinch Customer Dashboard to show as an incoming number on a voice call.  If we do not have a DID in your region, then we can acquire one for you. Please get in touch.


Migration of customers' existing DIDs is also an option, please contact Sinch support if that is your case.
