+## Use cases
+
+### Signal for attorneys
+
+People we met at the IFF 2019 started experimenting with using Signal as
+point of contact for attorneys and their clients or whistle-blowing
+sources.
+
+They have a script that makes it possible to validate a land-line phone
+at the attorney's office to create a Signal account attached to it. This
+Signal account can then be used from Signal on a desktop computer, or
+even better, on Tails.
+
+This setup has several advantages:
+
+- Giving your office telephone to a client doesn't look as dodgy as
+ sharing your personal mobile phone number.
+- Attorneys are obliged to have a land-line phone as their official
+ point of contact.
+- Attorneys can keep their work and personal contacts separate.
+- Attorneys can attend their work Signal even when outside of office and
+ keep secure communications with their clients even when traveling.
+
+An important limitation for this to work is that you can't change the
+name of contacts that were added, using a phone number, to Signal
+desktop. There is a feature request for this upstream.
