Abstract (en)

[origin: WO0245399A2] The invention enables an IP address to be "smuggled" through an existing CTI protocol and through the PBX to an IP Telephony Gateway (ITG) function by utilising a component to identify the Dialled Number as a special case which can be used "as is" by the ITG function to make the call to the specified IP address. The invention gets the IP address to the ITG function, which currently works off the DN (Dialled Number) from the switch, and resolves it on the ITG card to an IP address. Preferably, the number supplied to the PBX looks like an existing Dialled Number (DN). The conventional IP quad notation is padded to form a 3 digits per octet representation of the IP address and so eliminate the need to support the "." of usual dot notation within an IP address. By representing the IP address as a normal number with digits only in the range 0-9, it can also be entered by, for example, Call Centre Agents, via existing dial-pads and does not require either special characters to be transported across CTI links which might require changes to the CTI specification or adapting ITG function APIs.
