[Asterisk-Dev] Transfer of variables to remote servers (new subject)

[Soren Rathje]

With the risk of beeing flamed from here to eternity.... Eherm.. On the
subject of Asterisk-to-Asterisk interchange one word that immediately came
to my mind was SS7, or rather SS7oIP.

By implementing a true IN into Asterisk would indeed bring Asterisk into the
big league and solve a lot of questions about interoperability and
connections to the "real world" of tier one carriers.

I am by no means an expert on this subject but I know from a previous
projects in Thailand that keeping track of a 6,500+ Cisco AS5300 VoIP
network without IN is hard work even on the billing and service activation
part where we did our part... :-)

Note, by implementing IN into Asterisk (in theory) it doesn't matter what
streaming protocol is used, PSTN, SIP, H323, MGCP, IAX or "IP over Avian
Carriers with Quality of Service" (RFC 2549), the voice stream can be routed
via a different path while call control is still handled by Asterisk.

Ok, I've had my saying.. I'll return to lurking mode..
