Callback Disconnect Sequence
The Dialer has the ability to send terminating characters, for instance an MF4 #, to clear the
local PTT line after a routed call has been made. After the user hangs up the telephone, the PTT
line will be disconnected for the time specified by the 103 register (On-hook Timing). The PTT
line will then be reseized, and the terminating characters will be dialled.

characters or used as terminating characters.
