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

[Race Vanderdecken]

Okay, there seems to be agreement as to how to do this. Doing ISUP and
TCAP is what I have heard from others I have proposed the same questions
to in the past.

Running the SS7 to PSTN interface on a "cisco" type box also has been
recommended by others. By "cisco" I mean any certified box that is
available to most of the VoIP guys. Having to purchase an X thousand
dollar box is not going to work. Have any of you looked at ss7box.com?

So, we need to create a SS7 socket interface to asterisk.

I have built several socket interfaces in the past that have worked in
commercial products. All were based on Stevens' Unix Programming and
Networking books.

Where do I find the socket interface on our "cisco" ss7 box?

I think this is a very valid point.

I would include ISUP & TCAP.  Ideally I would rather have my SS7 A- 
links terminate in a purpose built box (ss7box, Cisco 2600 with ss7  
software).  I would want Asterisk to handle the ISUP/TCAP over IP  
(SIGTRAN ??).   I think it will be nearly impossible to get Asterisk- 
ss7 certified by an RBOC for interconnect to their network.  Without  
certification it is only good as a toy in a lab scenario.   Using an  
existing box (cisco) would make the certification process much  
easier, unnessesary.
