Two telephone network mode automatic call having call number user memorised and following set time signal loss automatic recall with network signalling call receipt.

摘要

The automatic telephone recall method has a telephone unit (1) which has called a user on one of two networks (30,31). The number called is memorised in the unit. After a set period has elapsed without communications, the number is automatically recalled across the network. The call network detects the call has been received and signals the user.
