feature request: hide caller id #404

Open electriquo opened 2 years ago

electriquo commented 2 years ago

It would very helpful if Simple Dialer would have the functionality to Hide the caller ID when making a call to a number that is not in the contact list, in the same spirit of CallerId Blocker (which cannot be found on Google Play) (for more information about GSM codes, see https://www.geckobeach.com/cellular/secrets/gsmcodes.php)

Thanks.

what does it need to implement this enhancement (on a technical level)?

electriquo commented 1 year ago

@sudwhiwdh without any familiarity with the code itself, a naive implementation would look like: given a number to dial, check whether it is in contacts. if it is, then issue the call. otherwise, prepend #31# to the given number and issue the call.

note that, #31# might be different in some cases. look at the link in the issue description.
