No. All packets are routed through the CPU for processing.
Minimal TCB, the most airtight SBA security model as specified by MSFT (firewalled off from the network, with no Internet Explorer, IIS or Windows networking)
No, SBA has separate external Ethernet connection at constant risk of attack
No, SBA has separate external Ethernet connection at constant risk of attack.
"Lifeline" ports to assure PBX and analog phones can still place calls into the PSTN in the event of a power loss.
12 analog lifeline ports, single T1/E1 PRI digital voice lifeline connection.
5 analog lifeline ports with single T1/E1 PRI digital voice lifeline connection.

Additional information on Note 3 - The signalling on the Genband products has historically not been handled by a network processor with only media being handled via the network processor. The signalling has historically been handled by the Linux IPTables, which has problems with high data rates and isn’t capable of providing wire-rate protection. Signalling encryption has historically been performed in software and may also be a limiting scale factor. Information as to whether this functionality has been migrated into Network processors in a recent release needs to be obtained to verify these perceived weaknesses.
Additionally overload control has historically been poor in comparison to other manufacturers.

Ease of Use and Certainty of Correct Operation
Single Integrated SBC/SBA Web Management Interface to achieve single look and feel across the SBC & SBA.
Yes No
TDM channel virtualization and visibility for VoIP calls
Integrated SBA management operations to acquire and confirm correct SBA operation e.g. SBA SW load identification, replication status, call status, etc.
Recovery partition in the SBA processing complex allows user to store an uncorrupted SBA & OS image for fallback in catastrophic crash
Yes, "one click" recovery
option
Network access available during SBA booting allows remote operator to load uncorrupted image in recovery partition recover from SBA catastrophic crash.
No, on-site re-boot only
Signed roll-up patch service from gateway vendor to simplify SBA patching and reduce customer IT costs:
• Gateway vendor is the single source of all required patches, vs. multiple disparate sources
• Simplified patch management procedure, vs. complex multiple disparate patch application
Lync SBAv2 compliance, Lync RBA (Resilient Branch Appliance) for Lync survivability over 3G/4G
Yes, first and only vendor
Multi-forest AD support for separating out AD query for monitoring network traffic and AD query for voice traffic

Ease of Lync Deployment
Integrated SBC co-existing with Microsoft® Lync™ Survivable Branch Appliance for:
• Protection of customer network via segregation and NAT, prevention of DOS, CAC
• Public/private IP network demarcation services
• Reduction of SIP trunking costs with multi-ITSP registration.
Yes
Not available as pure E-SBC with Lync™ SBA
Configurations, requires MSBR configuration
Full on-board call forking to support multiple call terminations to both SIP and TDM/analog clients and simplify Lync migration into the branch
Yes, up to 8 analog/TDM/SIP call destinations per forked call
Limited on-board call forking (10 SIP endpoints only) & consumes SIP licenses
Programmable AD Integration to support custom AD-supported call flows. No
Optional AD caching to optimize network traffic & prevent lost phone calls during AD server outage.
No, support for intermittent failure only
Lync SBAv2 compliance, Lync RBA (Resilient Branch Appliance) for Lync survivability over 3G/4G
