Business Phone Systems System Setup & Configuration 1 — Questions and Answers
Question 1: What information is typically required to provision a new IP phone on a cloud system?
- MAC address of the phone, assigned extension number, and SIP credentials (Correct answer)
- Serial number of the phone and billing account number
- Physical mailing address of the office and zip code
- Employee's email address and department name only
Correct answer: MAC address of the phone, assigned extension number, and SIP credentials
Provisioning an IP phone requires its MAC address to identify the device and SIP credentials (username/password/server) to register it.
Question 2: What is auto-provisioning (zero-touch provisioning) for IP phones?
- The phone automatically downloads its configuration from a provisioning server when plugged in (Correct answer)
- A feature that assigns extensions automatically to new employees
- Automatic firmware updates for all IP phones overnight
- A system that orders replacement phones when one fails
Correct answer: The phone automatically downloads its configuration from a provisioning server when plugged in
Auto-provisioning lets IP phones fetch their configuration files from a server at boot, eliminating manual setup of each device.
Question 3: What is a VLAN (Virtual Local Area Network) used for with VoIP phones?
- Separates voice traffic from data traffic on the same physical network for better QoS (Correct answer)
- Creates a private network for external callers
- Encrypts all VoIP traffic between phones
- Assigns dynamic IP addresses to IP phones
Correct answer: Separates voice traffic from data traffic on the same physical network for better QoS
Placing IP phones on a dedicated voice VLAN isolates voice traffic, making QoS prioritization easier and reducing interference from data traffic.
Question 4: What is PoE (Power over Ethernet) in the context of IP phones?
- Delivers electrical power through the Ethernet cable so IP phones don't need a separate power adapter (Correct answer)
- A high-speed ethernet standard for phone data transfers
- A protocol for encrypting phone traffic over the LAN
- A type of network switch optimized for VoIP traffic
Correct answer: Delivers electrical power through the Ethernet cable so IP phones don't need a separate power adapter
PoE allows network switches to supply power to IP phones through the same Cat5/6 cable used for data, simplifying installation.
Question 5: What should be configured first when setting up a new business phone system?
- The dial plan and call routing rules before adding extensions and devices (Correct answer)
- Individual voicemail boxes for each employee
- Conference bridge codes for the entire company
- Caller ID names for all extensions
Correct answer: The dial plan and call routing rules before adding extensions and devices
The dial plan defines how all calls will be routed, so it must be established before extensions and features that depend on it are configured.
Question 6: What is a SIP registrar server?
- A server that authenticates and tracks the current IP address of SIP devices so calls can be routed to them (Correct answer)
- A server that stores voicemail messages
- A hardware device that bridges SIP to PSTN calls
- A cloud database of all business phone numbers
Correct answer: A server that authenticates and tracks the current IP address of SIP devices so calls can be routed to them
The SIP registrar accepts REGISTER requests from SIP phones, storing their current IP location so the system knows where to send incoming calls.
