In simple terms SS7 is the suite of protocols used by all major networks for interconnecting their 'real' telephone exchanges. There are many telecomms platforms which only support SS7 if you want to connect into them you will need SS7 support. Note that SS7 is not limited to 'call' data, there are many protcols which sit on the SS7 stack such as MAP (Mobile Appilication Part - used in GSM - directly talk to proper SMSC's), INAP (Intelligent Networks Application Part - used for intelligent networks, deploying services such as pre-paid, tele-voting). The equivalent of ISDN/PRI in SS7 is ISUP (ISDN User Part) which is typically used in modern networks for inter-exchange call routing (some older networks use TUP - Telephony User Part - even older networks use non SS7 ), which I would suppose is the first step for Asterisk having not followed it myself. Typically there are very stringent interconnect tests required for anybody looking to interface with another operators SS7 network, not like ISDN/PRI lines which are designed for PBX use. Of course networks are moving towards consolidating their IP/Telecomms backbone so SS7 is being routed over IP - http://www.sigtran.org/. BR /Kev,
