6 APPLICATIONS
The applicability and the means of use of the VoiBridge equipment are presented below.
a) the equipment functions as SIP Trunking between an IP PBX and the mobile
telephony network (GSM / UMTS / CDMA).
One or several subscribers registered to an IP PBX equipment initiate calls to the mobile
telephony network.
These calls are transmitted to the VoiBridge equipment, which achieves the translation of the IP
calls into mobile calls.
Finally, by using the TOPEX box we will have a mobile to mobile conversation instead of an IP
to mobile call.
