The Google evidence is that AT&T Flexible Reach is following model (a), where individual Enterprise SBCs are certified. It's becoming more common for SIP trunking that only the CPE SBC is certified, allowing the customer some freedom on the actual SIP PBX or gateway behind the Enterprise SBC.
For example, Google shows claims that the Avaya Aura, Sipera E-SBC, and Net.com Enterprise SBCs are supported by AT&T Flexible REach.
That seems quite problematic for those who want to use/can't afford an SBC per se, or at least an approved SBC, for their network edge. -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/
