ABSTRACT:
To allow a call received from an accommodated device to arrive at the other party by diverting the call from an IP network to a detour network even with different numbering systems between communications over the IP network and over the detour network. A VoIP gateway apparatus1includes an ISDN terminal side IF portion101, an IP network side IF portion102, an ISDN network side IF portion103, a condition storage portion109, a detour determining portion108, and a number editing portion106. The detour determining portion108determines whether a call arriving at the ISDN terminal side IF portion101satisfies a detour condition stored in the condition storage portion109or not. If so, the number editing portion106edits the called party number of the call under a number editing condition stored in the condition storage portion109and then transmits it from the ISDN network side IF portion103. If not, the call is transmitted from the IP network side IF portion102without editing the called party number.
