| 摘要 |
A switching system that enables the provision of a hold tone in a hold operation to be performed efficiently, comprising a first communication terminal (100) capable of packet communications, a second communication terminal (110) that performs packet communications with the first communication terminal (100), and a network (130) that connects the first communication terminal (100) and second communication terminal (110). When the first communication terminal (100) puts the second communication terminal (110) on hold, the first communication terminal (100) converts hold data (103) that it possesses to audio that can be interpreted by the second communication terminal (110) by means of a hold data conversion section (104), and transmits the converted audio as a hold tone.
