I would like to add a few questions to this one:
(1) Do the Universal Gateways support CCS No.7 according to the ITU-T White Book? I read in a glossary of one of the Cisco docs that CCS7 is equivalent to SS7. Is there a 1-to-1 mapping, like between BS7799 and ISO 17799?
(2) Do they support CAS MFC R2?
(3) Do they support ISDN PRI DSSI?
