VOIP Trunk Channels| Call Recording Reference

Configuration for the Passive recording of VOIP Trunks - Initial steps

Passive recording: When recorded media streams are retrieved from the network traffic by monitoring the Mirror Port on the network switch.
Terminating recording: When recorded media streams are sent by some device directly to the recorder (e.g. BIB enabled Cisco phones, SIPREC enabled device or similar protocol).

SIP trunk is configured in config hw voip trunks mode.

The following steps are assumed to be completed in the prior configuration described in this section:

WinPcap drives installed
VSLogger server software installed
CLI Tool used to enable voip trunks hardware. refer to config hw- Passive VOIP

How to use CLI Tool - refer to CLI Tool Overview

Attention!!: most of the corresponding configuration functionality is also available within Versadial VSLogger Monitor graphical interface. Select setup View Setup View and the corresponding section (General, Storage, Channels, etc..).

VOIP Trunks (hw voip trunks) channels

For this example, we assume that Administrator enabled hw voip trunks installed in the system. After reload, Administrator can expect following channel list.

cli>(config)
->channel list
channels
----------------------------------------
ch# |type |hwch# |hw |enabled
----------------------------------------
.....
9 SIPTRUNK_CH 9 voip n
10 SIPTRUNK_CH 10 voip n
11 SIPTRUNK_CH 11 voip n
12 SIPTRUNK_CH 12 voip n
.....
cli>(config)

Open Individual channel in configuration mode.

cli>(config)
->channel 9
cli>(config-ch_9)

Display current channel setting.

VOIP trunk channel specific parameters

Command Format	Description	Extra Notes
mapto [none\|port\|sdpsess]	map specific channel to port or to sdp session	none- channels in trunk allocated dynamically, in order from 1st to last port - specific channel numbers associated with specific session port (rare situation) sdpsess - - specific channel numbers associated with trunk id specified in SDP session (sometimes happen)
nortptimeout [1-10]	set no rtp timeout (sec). default 3 secs	Session considered lost if no RTP received during this time
reversedir [y\|n]	reverse call direction	Used, if direction is captured in reverse.
gendtmf [0-3]	generate DTMF tone according Named Telephone Event (rfc2833) 0- none, 1- near-end (outbound rtp stream) , 2 - far-end (inbound), 3 -all	applicable only for sip protocol
hndldtmf [0-1]	handle DTMF events (rfc2833) 0- near-end (outbound rtp stream) , 1-all	applicable only for sip protocol
