Local VoIP and RoIP
Local VoIP and RoIP refer to the feature of Eventide NexLog Recorders that
provides the capability to record VoIP and RoIP without using an Eventide VoIP
Gateway. This local IP recording capability is also used for recording IP-based
P25 radio systems (by EF Johnson and others).
The NexLog Recorders support capturing and recording voice or radio traffic
appearing in RTP packets on an Ethernet network. The recorder is able to
monitor and record Ethernet Voice over Internet Protocol (VoIP) or Radio over
Internet Protocol (RoIP) traffic directly.
To configure the recorder for VoIP (or RoIP) traffic, you must first add a virtual
board of type Local IP and the required number of virtual channels to the
system.

TX port and an RX port for each channel, the template looks like this:
