Receive a Call
RED ALERT VoIP emergency telephones automatically go off-hook (auto-answer) when called. A
conversation can then take place.
Multicast Broadcast
When making a multicast call, the SIP server sends the page request to a specific IP address and multiple
telephones accept and play the subsequent audio. GAI-Tronics’ VoIP telephones can be programmed for
up to eight multicast addresses to permit the receipt of multicast broadcasts from different sources or to
enable zoning of broadcasts. Each multicast address can be assigned a priority (via programming) to
define broadcast override. A telephone with multicast enabled can still make and receive normal calls
(peer-to-peer or SIP server). Normal calls can be assigned a priority level, defining whether calls can
override multicasts or vice versa.
Monitoring and Reporting
Each telephone can recognize and generate several hardware and configuration fault condition alarms.
These alarms can be signaled to a remote site using three methods:
•
Syslog output over TCP
•
SNMP (Simple Network Management Protocol)
•
TMA (Telephone Management Application) software (purchased separately)
N
OTE
:
The TMA software permits
system
monitoring and data collection/reporting from a central
location.
Available alarms are:
•
handset integrity loop (if applicable)
•
configuration error
•
cold reset (power cycle)
