Automatically reducing communication bandwidth to coincide with the state of a communication call by a communication terminal. If a first telecommunication terminal puts a second telecommunication terminal on hold, thefirst telecommunication terminal transmits a transport message that reduces the bandwidth of the call to a low speed data link. When the first telecommunicationterminal wishes to again be in communication with the second telecommunication terminal, a transport message is utilized to restore the communication bandwidth. If a first communication terminal calls a second communication terminal and the second communication terminal is busy, the first communication terminal reduces the bandwidth of the communication call to that of a low speed data link. When the second telecommunication terminal becomes idle, the second terminal sends a message to the first terminal indicating the idle state. The first telecommunication terminal then uses a transport message to increase the communication bandwidth to the desired amount and engages the second communication terminal in a communication call.
