Eventide VoIP Gateway configuration
The following information describes the Eventide VoIP Gateway.
The
Eventide VoIP Gateway
is a separate, rack-mounted unit that passively
captures VoIP data from the VoIP phone sets on the network and interfaces with
the NexLog Recorder via the LAN. The gateway serves as an intermediary
between the network and the recorder.
In the event your recorder installation requires more than the 96 channels
supported by a single VoIP Gateway, or if you wish to “tap” the VoIP system from
different locations, NexLog Recorders can support more than one VoIP Gateway.
(Tapping is the term used for creating permanent access ports for network
monitoring.)
Eventide VoIP Gateway Topology
The following figure shows an example of the network topology for an Eventide
VoIP Gateway implementation.
