From TBwiki
SS7 is a signaling protocol which is used to set up and tear down phone calls.
TelcoBridges provides SS7 support with all of its media gateway, VAS development platform and monitoring devices. SS7 functionality is licensed separately and can be provided at initial purchase or added later on via a software key.
Systems developed using TelcoBridges hardware can support up to a maximum of 64 point codes. It is worth noting that a single poitncode can be used for 2 or more devices configured as a single system.
