How to use the hotline service:
Activating the service
User A picks up the phone and dials *61*TN#. Then, user A can hear an announcement indicating that the service is registered. User A has been assigned the instant hotline service right. The variable TN indicates user B's number.

Using the service
User A picks up the phone and hears the ringback tone. If user B picks up the phone, user A talks with user B.

Deactivating the service
User A cannot deactivate the service using the phone number for which the instant hotline service is enabled. User A needs to use another phone number for which the hotline service is enabled and dial #61*TN# to deactivate the instant hotline service. TN is user A's phone number.
