ACA Gateway Configuration & Management 2 — Questions and Answers
Question 1: In AudioCodes gateway configuration, what is an 'IP Group' used for?
- To represent a logical entity such as a SIP trunk or IP-PBX for routing and policy purposes (Correct answer)
- To define a subnet of media relay addresses
- To group physical Ethernet ports
- To configure VLAN membership for voice interfaces
Correct answer: To represent a logical entity such as a SIP trunk or IP-PBX for routing and policy purposes
An IP Group represents a logical signaling entity (e.g., SIP trunk, IP-PBX) and is referenced in routing rules, manipulation rules, and call admission control policies.
Question 2: What is the function of the 'SIP Interface' parameter in AudioCodes Mediant configuration?
- It defines the local IP address, port, and transport protocol used for SIP signaling (Correct answer)
- It specifies the codec list for media negotiation
- It configures the physical Ethernet interface for voice traffic
- It sets the registration expiry timer
Correct answer: It defines the local IP address, port, and transport protocol used for SIP signaling
A SIP Interface specifies the local UDP/TCP/TLS port and IP address the device uses to send and receive SIP signaling messages.
Question 3: Which AudioCodes configuration element is used to manipulate SIP headers before forwarding a call?
- Message Manipulation Rule (Correct answer)
- Dial Plan Rule
- Prefix Tree
- Call Routing Table
Correct answer: Message Manipulation Rule
Message Manipulation Rules allow modifying, adding, or removing SIP headers and body parameters as calls pass through the gateway.
Question 4: What does 'Registration Account' configuration on an AudioCodes gateway enable?
- The gateway to register a SIP URI with a remote proxy on behalf of connected endpoints (Correct answer)
- Local user authentication for the web GUI
- SNMP trap destination registration
- DNS-based SRV record advertisement
Correct answer: The gateway to register a SIP URI with a remote proxy on behalf of connected endpoints
Registration Accounts allow the gateway to send SIP REGISTER messages to a remote proxy, enabling the device to appear as a registered SIP UA for inbound routing.
Question 5: In AudioCodes Mediant, what is the role of 'Coders Groups' (codec groups)?
- They define an ordered list of audio codecs offered during SDP negotiation (Correct answer)
- They group physical DSP resources by capacity
- They assign DTMF relay methods per call leg
- They configure jitter buffer depths per endpoint
Correct answer: They define an ordered list of audio codecs offered during SDP negotiation
Coders Groups define the priority-ordered list of audio codecs the gateway will offer and accept in SDP, controlling codec negotiation with remote peers.
Question 6: Which HTTP method does AudioCodes OVOC use to push configuration updates to managed devices?
- PUT
- GET
- POST (Correct answer)
- PATCH
Correct answer: POST
OVOC uses HTTP POST requests to push configuration data and management commands to managed AudioCodes devices.
