Each channel is associated with a MAC or IP address (or is dynamically
assigned). Traffic to this address is considered inbound and traffic from it is
considered outbound.
RTP Mixing Mode
: Specifies the type of audio stream mixing for the recording.
Valid values include:
Rtp Mux None
: (default) No mixing is performed. The channel must be
set up to receive only a single RTP stream at any given time.
Rtp Mux Dir
: Mix inbound and outbound audio streams belonging to a
VoIP device (that is, mix traffic going in both
directions
). Direction mixing
is typically used with the PCAP method, because the audio streams
could be coming in from any port in the range.
Rtp Mux Port
: Mix audio streams from multiple ports, where each port
carries a separate audio stream. Port mixing is typically used with the
UDP method.
Rtp Mux Ip Port
: Mix audio streams from a destination IP address and
port. IP Port mixing is used with the UDP method or SIP Trunk signaling.
Rtp Mux Ip Ssrc
: Mix audio streams by detecting which stream a packet
belongs to using the RTP packet's SSRC field. Only recommended in case
where IP_PORT cannot be used due to multiple streams received on the
same port
Signal Protocol
: Specifies the type of signaling used. See
Section: 2.1. Features
for more information on the supported signaling types. Valid values include:
Rtp Sig None
:(default) Audio data is recorded without any call metadata
and Start/Stop is based only on RTP Stream presence and SSRCs
Rtp Sig Sip Trunk
: SIP Trunk, which is used for trunk-side recording
and not station to station calls.
Rtp Sig Zetron Rds
: Zetron RDS RoIP systems recording.
Rtp Sig Cisco Forked
: Used for Built-in-Bridge recording from Cisco IP
phones.
Rtp Sig Telex Ip223
: Telex /Vega IP radio recording when the Telex is
connected to a Conventional Radio System
Rtp Sig Telex Ip223 Trunked
: Telex/Vega IP radio recording when the
Telex is connected to a Trunked Radio System
Rtp Sig Efjohnson
: EF Johnson P25 signaling.
RTCP Ports
: Specifies the location of RTCP ports when RTP Ports
specifies multiple ports (e.g., a range). This is used to ignore any signals
on the RTCP ports so as to avoid interpreting them as RTP. Valid values
include:
