Definitions
- the sec- ond subnetwork 3 comprises, or is connected to a registration device 17, such as a gatekeeper in an H.323 IP telephony system.
- FIG. 2 shows an embodiment of the invention.
- the first and second subnetwork are a telecommunications network 101 and a data communications network 103, respectively, interconnected by at least one gateway 105.
- the telecommunications network 101 is a public switched te- lephony system (PSTN) and the data communications network 103 is an IP network, such as the Internet.
- PSTN public switched te- lephony system
- IP network such as the Internet.
- the telecommunications network 101 comprises at least one call directing means 111.
- this call directing means is normally a service control point (SCP) or a service switching and control point (SSCP).
- SCP service control point
- SSCP service switching and control point
- the IP addresses have the format xxx.xxx
- the IP tele- phone numbers that is, the telephone numbers in the gatekeeper's 117 domain
- the telephone numbers in the telecommunications network that is in the SCP's 111 domain all belong to the number series 700-xxxx, each x representing an arbitrary digit.
- the gatekeeper 117 comprises a table 118 providing associations between IP addresses and IP telephone numbers. It also comprises a table 120 having the same format, but the IP telephone numbers registered here will be numbers taken from the list 119 of idle numbers, which, in this embodiment, is found in the SCP 111.
- the terminals connected to the data communications network may be devices in- tended specifically for telephony through an IP network or computers or computer terminals equipped with the necessary hardware and software for IP telephony.
- Step S308 The registration is refused. End of procedure.
