[asterisk-ss7] chan_ss7 vs libss7 vs chan_zap

[hungtq]

       Hi.
       I'm designing a call center. I want to use Astersik's solution
for this one. In my project I need solution for all signaling type,
especially SS7. I wonder whether SS7 is an open source or not. If it is
not an open source how can I develop my project that support SS7 based
on Asterisk (my perpose is to be able to complete my project more easily
and saving cost). Can you give me some suggestion ?
       Best regards,
       Tara.

       Either through a library that provides the SS7 signaling 
       (libss7/chan_zap) or through a channel driver that does it all 
       (chan_ss7).

       Yes, I think with any of the current SS7 solutions you can use
Digium 
       cards for SS7.  I wrote libss7 in fact using Digium cards here at
work.
