Confidentiality Notice
This manual is provided solely as an installation, operation, and maintenance guide and contains sensitive
business and technical information that is confidential and proprietary to GAI-Tronics. GAI-Tronics
retains all intellectual property and other rights in or to the information contained herein, and such
information may only be used in connection with the operation of your GAI-Tronics product or system.
This manual may not be disclosed in any form, in whole or in part, directly or indirectly, to any third
party.
General Information
GAI-Tronics’ Class I, Division 1 VoIP (Voice
over Internet Protocol) telephones are
constructed of cast aluminum and are
weatherproof and corrosion resistant. User
operation is identical to that of a standard
analog telephone—simply lift the handset and
dial the desired telephone number.
GAI-Tronics’ VoIP telephones connect to a
10/100 BaseT Ethernet LAN (Local Area
Network) and operate from PoE (Power-over-
Ethernet) or an external power source. VoIP
telephones provide point-to-point
communication between personnel over an
existing LAN.
This manual applies to the following models:
• Model 352-701 Division 1 VoIP
Telephone
• Model 352-703 Division 1 VoIP
Telephone with Headset
These VoIP telephones feature real-time alarm
reporting. System supervisors monitor each
telephone’s activity to address caller needs or
maintenance issues immediately. The
telephones have four user-configurable inputs
and two outputs for customer use.

Features and Functions
GAI-Tronics VoIP telephones include the following features:
•SIP compatible (RFC3261)
•real-time alarm reporting via SNMP or syslog
•PoE (Power-over-Ethernet) compatible; Power Mode A, Class 0
•configurable via web page, serial link, or download
•four configurable auxiliary inputs
•two configurable dry-contact outputs
System Requirements and Limitations
These VoIP telephones require PoE (Power-over-Ethernet) or a local 24–48 V dc power source for
operation. Two VoIP telephones can be connected in a peer-to-peer configuration without the need for a
LAN. A 10/100 BaseT Ethernet network with a SIP (Session Initiation Protocol) server is required for
systems containing three or more VoIP telephones. Conferences are limited by the customer’s LAN
media capabilities and the services available at each end point.
VoIP Subscriber Tips
New and existing subscriptions to an interconnected VoIP service provider should address the following
points:
•Provide accurate physical address information to the VoIP service provider to ensure that emergency
services can quickly be dispatched to the location.
•Be familiar with the VoIP service provider’s procedures for updating the address and promptly update
address information in the event of a change.
•Have a clear understanding of any limitations of the local 911 service.
•Be aware that VoIP telephone services may not work if the power is out or the Internet connection is
down. Consider installing a backup power supply, maintaining a traditional telephone line, or having
a wireless telephone as a backup.
•For questions about interconnected VoIP and 911, or VoIP in general, see
http://www.fcc.gov/cgb/consumerfacts/voip.html.
