A telephone relay apparatus comprising: a specific storing unit that stores a specific telephone number of at least one specific telephone terminal that is used by a specific terminal user; a periphery storing unit that stores a peripheral telephone number of each peripheral telephone terminal expected to exist in the periphery of said specific terminal user, said peripheral telephone number being stored together with periphery requirement data; a request receiving unit that receives a line connecting request from a telephone terminal of a telephone user to said specific telephone terminal; a specific line connecting unit that tries to connect said telephone call line from said telephone terminal to said specific telephone terminal with the use of said specific telephone number in response to said line connecting request; a requirement acquiring unit that acquires at least one piece of said periphery requirement data from user scheduled data about said specific terminal user having said scheduled date and time matching a present date and time, when said telephone call line is not connected; a periphery selecting unit that selects at least one of said peripheral telephone terminals in accordance with said one or more pieces of periphery requirement data acquired; and a telephone call unit that tries to connect said telephone call line from said telephone terminal to said selected peripheral telephone terminal, with the use of said peripheral telephone number, said periphery storing unit storing information of another user who carries said peripheral telephone terminal as at least one piece of said periphery requirement data together with said peripheral telephone number, said user scheduled data containing information of said another user being stored as said periphery requirement data; said requirement acquiring unit acquiring the information of said another user from said user scheduled data about said specific terminal user of said specific telephone terminal having said scheduled date and time matching said present date and time, when said telephone call line is not connected; said periphery selecting unit selects said peripheral telephone terminal of said acquired another user; charaterized in that said telephone call unit generates a guidance message containing a name of said specific terminal user of said specific telephone terminal and transmits the generated guidance message to said telephone call line from said telephone terminal to said connected peripheral telephone terminal. a specific storing unit that stores a specific telephone number of at least one specific telephone terminal that is used by a specific terminal user;
