Question 1

AudioCodes 'Survivability' feature on a branch SBC ensures:

Accepted Answer

Local calls continue to function during WAN outage by the SBC registering endpoints and routing calls locally

Answer

Survivability mode activates when the SBC loses connectivity to the central call control system, allowing it to register local endpoints and route intra-branch calls independently.

Question 2

Which AudioCodes SBC feature translates between different SIP variants and fixes interoperability issues between heterogeneous vendors?

Accepted Answer

SIP Normalization (via Message Manipulation Rules and SIP Profile)

Answer

SIP Normalization uses message manipulation rules and SIP profiles to modify headers, add/remove parameters, and adjust behavior to ensure interoperability between SIP implementations from different vendors.

Question 3

In AudioCodes Teams Direct Routing, which FQDN pattern does Microsoft require the SBC certificate's Subject Alternative Name (SAN) to match?

Accepted Answer

The FQDN used in the SBC's configuration on the Microsoft Teams Admin Center (must match exactly)

Answer

Microsoft requires the SBC certificate's SAN to exactly match the FQDN configured in Teams Admin Center for Direct Routing, ensuring the TLS certificate validates the SBC identity.

Question 4

What is the role of 'Local Media Optimization (LMO)' in AudioCodes Teams Direct Routing deployments?

Accepted Answer

Allows media to flow directly between Teams clients and the PSTN SBC without traversing the Microsoft media processors, reducing latency

Answer

LMO is a Microsoft Teams Direct Routing feature that allows RTP media to bypass Microsoft media processors and flow directly between the Teams client and the SBC for lower latency in optimized deployments.

Question 5

AudioCodes 'ARM (AudioCodes Routing Manager)' is used in multi-site deployments to:

Accepted Answer

Provide centralized SIP routing policy management across multiple SBCs from a single management point

Answer

ARM centralizes call routing rules and policies for multiple AudioCodes SBCs, allowing administrators to manage routing from a single interface rather than configuring each SBC independently.
