[Asterisk-ss7] Let us design an open source SS7 interface for Asterisk

[Andrew Edem]

But what's the point of putting TCAP in asterisk? Are you planning on
writing applications for asterisk that use TCAP? Or, do you want
asterisk to be an SCP?

Personally, I think most people out there would like to see asterisk be
able to terminate calls to SS7 networks. For that, you only need ISUP.
