Multicast Broadcast
When making a Multicast call, the SIP server will send a paging request to a specific IP address and
expect multiple telephones to 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 which can override which. 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
SMTP mail message
Telephone Management Application (TMA) software (purchased separately)
Available alarms are:
Handset integrity loop (if applicable)
Configuration error
Cold reset (power cycle)
Warm reset (internal command)
Keypad error (if applicable)
Key hook (off hook status, if applicable)
Register fail
Audio Path Test (speaker/microphone test)
