摘要:
A Multicall telephony system has a first land-line telephone connected to a central switch in a land-line telephone network and a server executing SW on a processor from a non-transitory medium, the server also coupled to the land-line telephone system by a service telephone number. In operation a user dials the service telephone number, and when connected, dials two or more telephone numbers separated by delimiters and followed by a terminator character, and the server, executing the software, dials the two or more telephone numbers separated by delimiters in the call from the first land-line telephone, and connects answered calls in a conference with the call placed by the first land-line telephone.
