<p>A system for providing remote program selection by a held caller in a telephone hold program system wherein a caller's line (2, 4) is connected to a holding circuit (84) and a program is transmitted to a held caller. When a line (2, 4) is being held by the holding circuit (84) a hold detector (85) causes an announcement to be coupled to the held line for instructing the held caller for remotely selecting one of a plurality of programs (92). The held caller sends select signals, in the form of voice or tone data, which are decoded and used to select the desired program source (92) to be coupled to the held line. The system includes a remote volume control (97) wherein a command signal sent by the held caller controls the volume level of the program supplied.</p> |
