✍️ Sample ACA Questions & Answers
1. AudioCodes 'WebRTC' support on the SBC enables:
The AudioCodes SBC bridges WebRTC clients (using DTLS-SRTP and ICE for NAT traversal) with standard SIP infrastructure, enabling browser-based calling without plugins.
2. What AudioCodes tool is used to monitor the health and status of an HA pair in real time?
The AudioCodes OVOC (formerly EMS) and the device's own Web Management Interface both provide real-time HA status, active/standby role display, and switchover controls.
3. Which log level should be used on an AudioCodes Mediant during a security investigation to capture detailed SIP message content?
Setting the syslog level to Debug (7) captures full SIP message details including all headers and body content, essential for security forensics and intrusion analysis.
4. What is the primary function of SIP in VoIP systems?
The primary function of SIP (Session Initiation Protocol) in VoIP systems is to manage the lifecycle of communication sessions. This includes initiating a call (e.g., ringing a phone), modifying session parameters (e.g., adding video), and gracefully terminating the session (e.g., hanging up). SIP acts as the control plane for setting up and tearing down calls.
5. In AudioCodes Teams Direct Routing, which FQDN pattern does Microsoft require the SBC certificate's Subject Alternative Name (SAN) to match?
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.
6. What does 'SRTP with SDES key exchange' mean in an AudioCodes SBC context?
SDES (Session Description Protocol Security Descriptions) embeds SRTP key material directly in SDP, making TLS mandatory for the SIP signaling to protect those keys.
