POTS Phone Line Options
In the event that an analog “POTS” line is not available, the following options have been evaluated and provided
satisfactory operation.
VoIP Service
A Cisco SPA 112 analog adapter has been tested and found to be a viable alternative to the “POTS” line
connection. The Cisco adapter emulates the “POTS” line by providing DTMF tones and line voltage.
Requirements:
•
Active Internet & Voice over IP accounts
o
VoIP adapter model confirmation is required for each individual VoIP service. (Cornell
completed the operational testing using VoIP service provided by Nextiva)
Disclaimers:
The 4800 offsite notification process requires a standard “POTS” line for proper operation. As with any
method of offsite voice connection, if the phone service, internal/external network or power system
fails, the 4800 system will not be able to connect to the offsite monitoring location.
The example VoIP service disclaimers below are generally included with service contracts.
Several manufacturers offer analog voice phone adapters. Please confirm with the current/prospect VoIP service
for the correct certified hardware device.

You may experience interruption of Service (or of certain features of the
Service) or degraded service quality at any time and without notice. You will
likely experience Service outages in the event of electric power outages
affecting your business.
•
Voice over IP requires that the infrastructure, on which the telephony system is
built, is capable of handling voice services. This includes the proper hardware
infrastructure (gateways, switches, routers, data/voice lines) and configuration
of Quality of Service (QOS) and VLANS on these devices.
