• entering, by the caller using the first cordless handset, a sequence which enables the two-way call feature;
• assigning, by the first base station, an alias code representing the identification number of the first cordless handset;
• sending, by the first base station to the paging terminal through the public switched telephone network in response to entering the sequence, data representing the telephone number of the line and the alias code;
• terminating by the first base station, the first communication link;
• transmitting, by the paging terminal after sending the data, to the second party a page including the data and the alias code;
• and
• initiating, by the second party after receiving the data and the alias code, a return call to the telephone number of the line by using the data;
