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
•

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.

Hardware Description
External
The Model 352-701 telephone contains a handset with an approved cable gland, standard keypad, volume
control button, and applicable approval labeling. The handset rests on a cradle with a magnetic reed
switch to signal the off-hook condition. Ten cover mounting bolts, located around the perimeter of the
enclosure’s flange, seal the enclosure (see Figure 2).
