Device Information
PCAP Ports and UDP Ports
: Specifies a port list (port numbers and/or port
ranges) for ports to record. All ports that are used by all channels must appear
in the list. The ports should also be specified in the channels specific pages.
Valid Range: 1-65535. Format: To specify multiple port numbers, separate them
with commas; for example: 1,2,3,5,9. To specify a port range, separate it with a
hyphen or dash; for example: 1-3. To specify multiple port ranges, separate the
ranges with a comma; for example: 1-3,7-12. To specify multiple port numbers
and port ranges, separate each type with a comma; for example: 1,2,5,9,12-
15,19,22-25,29,30. For readability and maintenance (and to avoid duplications),
it is recommended that you specify port numbers in numerical order.
Note: For
PCAP Ports
, the smaller the range, the better the performance, so it is
a good practice to identify only those ports that will be used. The ports belong to
VoIP devices such as IP phones, IP softphones, IP PBX ports, or other VoIP
endpoints on the network that you wish to record. Any packet received by the
recorder that uses ports in this list as either destination or source will make it
past the filter and be processed by the recorder.
Important! For UDP Ports
, it is very important to specify only the ports that
will be used, because opening these ports will consume resources on the
recorder. For example, specify 3,5 rather than 3-5 if port 4 will not be used.
UDP Multicast Addresses
: Specifies one or more IP multicast group addresses
from which to record. [Join or subscribe to.] Format: to specify multiple IP
multicast group addresses, separate them with a comma; for example:
239.1.1.1,239.1.1.9.
UDP Multicast Interface IP
: Specifies the IP address of the NexLog Recorder’s
network interface device which will be used to capture the multicast traffic.
SIP Endpoint Config
: Specifies a special parameter to configure the NexLog
Recorder as a SIP Trunk endpoint instead of its usual configuration as a "listen
only" device. Contact Eventide support for assistance in configuring this
parameter.
PCAP Devices
: Ethernet Device name. Specifies the NexLog Recorder’s network
interface device (NIC) containing the Ethernet port that will be used to record
RTP data. Valid Values: eth0, eth1, etc. Typically, one Ethernet port on the
recorder is used to record the VoIP traffic sent to the recorder and one port is
