I'd be interested to hear more detail - why do we need both SS7 amd CAS for 800
calls?
What are the security issues with SS7?

              Gents,
Just a few comments:
1)   SS7 and CAS compliment each other, thus for an advanced 800-calls we
must use both!
2)   About 15% LECs  still use MF signaling;
3)   Many customers, such as banks, prefer MF to interconnect to
IP-backbone due to security  issues with SS7.
Regards,
Lev.
