System Setup & Configuration Flashcards

What information is typically required to provision a new IP phone on a cloud system?

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.

What is auto-provisioning (zero-touch provisioning) for IP phones?

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.

What is a VLAN (Virtual Local Area Network) used for with VoIP phones?

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.

What is PoE (Power over Ethernet) in the context of IP phones?

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.

What should be configured first when setting up a new business phone system?

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.

What is a SIP registrar server?

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.
