recording system. The IP phone will check and respond to SIP messages coming from
these IP addresses. If all of these parameters are left undefined, the active VoIP record-
ing feature is disabled.
A whitelist can also be configured for RTP/SRTP packet destination authentication
using the "recording destinationN" parameters (where N is a number from 1 to 6).
These parameters are used to specify trusted IP addresses corresponding to the desti-
nation where the RTP/SRTP packets should be sent. The IP phone will check to see if
the destination IP addresses are trusted before sending the duplicated RTP/SRTP
packets. If all of these parameters are left undefined, no authentication checks will be
performed.
When a recording session is in progress (even during a conference call), the IP phones
display a recording icon (i.e. black circle) on screen indicating the recording status.
Moreover, the phone will, by default, play a periodic audible beep tone through the
selected audio path notifying users that their call is being recorded. Playback of the
beep tone is optional and if required, administrators can change the tone interval to
play every 15, 30, 45, or 60 seconds (or disable it entirely) using the "recording peri-
odic beep" parameter. Administrators can also determine the direction of the beep
tone by defining the "recording beep direction" parameter in the configuration files.
The direction can be set to local (i.e. tone played on the local phone, audible in hand-
set, loudspeaker, or headset), network (i.e. tone played to the remote phone), or both
local and network.
Note:
In addition to the aforementioned parameters corresponding to the active IP voice
recording feature, the transport protocol parameters for SIP services (i.e. "sip serv-
ices transport protocol" and "sip services port") must also be defined in the con-
figuration files.
