Troubleshooting and Diagnostics · System Troubleshooting
While monitoring an IP Office system using the System Status Application (SSA), a technician notices an alarm stating 'VCM Resources Full'. Users are reporting that they cannot make external calls or use conference features intermittently.
Which of the following scenarios is the most likely cause of this resource exhaustion?
Show answer & explanation
Correct answer: B
VCM (Voice Compression Module) channels are required for transcoding between IP-based audio (SIP/H.323) and TDM-based audio (Analog/Digital phones or PRI/Analog trunks). If there are many SIP calls connecting to non-IP endpoints, VCM channels can be depleted, triggering the alarm.

System Configuration and Administration · System Configuration
A technician is configuring a new SIP trunk and needs to ensure that emergency calls (911/999) always use a specific outgoing CLI, regardless of which user places the call.
Where should this CLI be configured to override all other user-specific settings for emergency short codes?
Show answer & explanation
Correct answer: B
In an ARS (Alternate Route Selection) short code, appending 'S' followed by the desired CLI (e.g., 911S1234567890) to the Telephone Number field forces that specific CLI to be sent for that route, overriding individual user CLI settings. This is standard practice for emergency routing.

Troubleshooting and Diagnostics · System Troubleshooting
An IP Office system is rebooting unexpectedly. The support engineer wants to capture the specific cause of the reboot for analysis.
Which type of file on the System SD card contains the binary dump of the system state at the time of the crash, and in which folder is it located?
Show answer & explanation
Correct answer: B
When an IP Office system crashes, it writes a memory dump file to the /system/primary folder on the SD card. These files are typically named with the hex address of the exception (e.g., .dmp files). Analyzing these requires Avaya engineering tools, but locating them confirms a software crash occurred.

IP Office Platform Architecture and Components · IP Office System Architecture
A multi-site company has a Server Edition Primary and a Secondary server. The administrator wants to ensure that if the Primary server fails, the IP phones at the Primary site automatically register to the Secondary server.
Which configuration field in the IP Office Manager for the Primary server's lines or extensions is critical for enabling this failover capability?
Show answer & explanation
Correct answer: D
For IP phones to failover in a Server Edition environment, the system must be aware of the backup server. This is handled via the 'Resiliency' configuration where the Secondary server is defined as the backup. The phones receive this list during registration. (Note: While 'Backup Registrar' is a field, in Server Edition, this is automated via the Solution settings/Resiliency options in the System configuration).

IP Office Platform Architecture and Components · one-X Portal Integration
An administrator is setting up a new user who needs to manage their own personal greetings and call forwarding settings via a web browser. The system is an IP Office 500 V2.
Which specific user right or license must be assigned to this user to allow access to the 'one-X Portal for IP Office'?
Show answer & explanation
Correct answer: D
Access to one-X Portal is not included in the Basic User profile. It requires an Office Worker, Teleworker, or Power User license/profile to be assigned to the extension.

IP Office Platform Architecture and Components · Session Border Controller
Case Study:
Scenario
A mid-sized logistics company uses an IP Office Server Edition with 500 users. They have recently deployed Avaya Workplace Client for mobile users.
Problem
Mobile users report that when they move from the office Wi-Fi to cellular data (4G/5G), their active calls drop immediately. However, they can re-establish the call manually after a few seconds.
Environment
- IP Office Server Edition R11.1
- Avaya Session Border Controller for Enterprise (ASBCE) deployed in the DMZ.
- Split-horizon DNS is configured.
Question
Which feature is likely misconfigured or disabled, preventing the seamless handover of the call from Wi-Fi to Cellular?
Show answer & explanation
Correct answer: D
Seamless roaming allows a call to persist when switching networks (Wi-Fi to LTE). This requires the client to detect the network change and send a re-INVITE with the new IP address. If the call drops, it indicates the session persistence or roaming handover configuration (often involving TLS and proper identity headers managed by the SBC) is failing.

System Configuration and Administration · Incoming Call Routing
A technician is setting up a new Incoming Call Route (ICR) for a DID that must route to the Reception hunt group during the day and to an Auto Attendant at night.
Which two components must be combined in the ICR configuration to achieve this time-based routing logic? (Select TWO)
Show answer & explanation
Correct answers: C, D
First, a Time Profile must be created to define what 'day' or 'business hours' means.
In IP Office, you create multiple ICR entries for the same number. One entry has the 'Business Hours' time profile assigned and routes to Reception. Another entry (often the default with no profile, or a 'Night' profile) routes to the Auto Attendant. The system checks entries with specific profiles first.
- Question 8Beginner
IP Office Platform Architecture and Components · IP Office Applications
True or False: In an IP Office Server Edition deployment, the 'System Status Application' (SSA) can be used to perform a graceful shutdown of the Linux operating system on the primary server.
Show answer & explanation
Correct answer: A
True. The System Status Application includes a 'System Shutdown' button for Server Edition systems (and Application Server), allowing for a safe halt of the OS services before powering off.
- Question 9Advanced
VoIP Protocols and Quality of Service · VoIP Protocols
A support technician is troubleshooting a fax issue over a SIP trunk. The fax machine starts the transmission but fails after the first page. The carrier supports T.38.
Which combination of settings in the SIP Line > VoIP tab is required to correctly negotiate T.38 Fax Relay?
Show answer & explanation
Correct answer: D
To support T.38, the SIP Line must have 'Fax Transport Support' enabled and set to T.38. This allows the system to detect fax tones and re-invite the session to switch from audio codec to T.38 protocol.
- Question 10Intermediate
Troubleshooting and Diagnostics · Log Analysis
When using the IP Office Monitor application to troubleshoot a 'One-way Audio' issue, which specific trace option should be enabled to view the IP addresses and ports being negotiated during the call setup?
Show answer & explanation
Correct answer: C
Enabling 'SIP Rx' and 'SIP Tx' (Receive and Transmit) in the Monitor trace filters captures the full SIP signaling, including the SDP (Session Description Protocol) body. The SDP contains the IP addresses and port numbers for the media stream, which is crucial for identifying NAT or firewall issues causing one-way audio.
