    1.10 +				when a subscriber communicates with an application (MOAT/AOMT messaging)
    1.11 +				he might not want expose his identity (MSISDN or IMSI);
    1.12 +				the aliasing feature (sometimes called hashing) deployed on an SMS gateway enables this communication and rewrites the subscriber's ID to some generated ID;
    1.13 +				the application can then send a response on a message without knowing subscriber's identity (on the gateway the ID is translated back to real ID – de-aliasing);
    1.14 +				use case:
    1.15 +					subscribers can vote in some survey,
    1.16 +					everyone will have one vote,
    1.17 +					but the owner of the survey will not know the opinion of particular subscibers
    1.18 +					because of missing their real IDs
