System Requirements and Limitations

A 100 baseT Ethernet with SIP Server is required for systems containing three or more VoIP Paging
Modules. The operation of this equipment is limited by the customer’s LAN media capabilities and the
services available at each end point. The performance of each module is dependent on the provision of
sufficient bandwidth and prioritization on the network to give the quality of service required. In addition,
the setup, installation, and software version of key components such as switches and routers can have a
significant effect on the operation of this equipment. Improper connections or loose cables can also affect
their operation.

The VoIP and WiFi Paging Modules require a local 120/240 V ac power source for operation.

The following network facilities should be provided (This may vary widely depending on how your
network is deployed):
 SIP proxy server (to route calls)
 SIP registrar server (frequently combined with proxy servers)
 TFTP server (for downloading configuration files).
 TCP Syslog server (for reporting alarms and external inputs)
 SMTP server (for reporting via email)
 STNP server (to synchronize the internal clock)
 STUN server (for NAT firewall traversal)
Dedicated systems, such as Gatekeepers, VoIP-enabled PABXs or soft PABXs may also provide these
functions.

The GAI-Tronics VoIP Interfaces only support Session Initiation Protocol (SIP) to RFC3261 Call Control
signaling.

In addition to direct access, peer-to-peer or via a SIP server, each interface/amplifier is capable of
receiving a Multicast broadcast. Multicast allows a single audio stream to be sent to multiple end points
simultaneously, to achieve multi-point paging or Public Address functionality over IP. Multicast requires
the use of a SIP server that specifically supports Multicast functionality and each interface must be
configured (enabled) to receive Multicast packets.
