During an operation, the patient experiences a medical complication and the surgeon has to make a critical call to a specialist. The specialist is not in the hospital but based in another city. With just a push of a button on the STENTOFON intercom station, the surgeon is able to contact the specialist and conduct a handsfree, two-way conversation to resolve the medical problem. The AlphaCom E exchange, integrated to a PBX, allows you to make instant external calls via the SIP gateway. Intercom users can connect with the telephony world by direct dialing from an intercom station to a telephone or through a call transfer in either direction.

STENTOFON Intercom and PBX integration Success Story

Shanghai Pudong International Airport (SPIA)

SPIA is currently the sixth busiest air freight hub and a major international gateway into China and East Asia. The airport employs STENTOFON standard VoIP protocols for audio encoding and control, and utilizes standard IP protocols for video and data transmissions, providing an area-wide network or broadcast and communication system at four key locations: the Traffic Operation Centre, the Airport Operation Centre, the Gate Wing and Gate Check In.

The system is run by four IP exchanges connected to a Cisco Call Manager PBX through 4 times 16 SIP trunk lines; integration is also provided to an 800m TETRA radio interface, the public network and PA. There are over 200 IP substations in the AlphaCom E system and their status can be seen as icons on a Graphical User Interface.
