application. When enabled in LD 17, IP Call Recording sends a modified
AML message for each call. The modified message identifies the call IP
endpoint and makes it possible to correlate the RTP packets for that call to a
particular IP Phone
IP Call Recording introduces the IE pair:
•

The IP IE pair is similar to the existing IE pairs:

•
The IP IE are optional in the Unsolicited Message Status (USM) (Active)
and USM (Restore) messages. Note the following:

•
A call recording application is provided with status update messages for the
call keys of any IP Phone it is monitoring. These USM messages contain
the IP address and port number information for the monitored IP Phone and
the remote party in the active call. By using a Layer 2 switch that supports
port mirroring, the call recording device can monitor the media stream for
the active call and record it.
Enhanced IP Call Recording
IP Call Recording provides a direct method of capturing and recording VoIP
calls. The feature enhancement implements a mechanism to record the
IP media stream to an external media-recording device by instructing the
IP Phone to send a duplicate media stream to a third-party call-recording
application. The third-party call-recording application provides the recording
and playing function for the IP calls.
This feature enhancement is supported on the Phase II IP Phone 2001, IP
Phone 2002, IP Phone 2004, IP Softphone 2050, IP Audio Conference
Phone 2033, IP Phone 2007, IP Phone 1110, IP Phone 1120E, IP Phone
1140E, IP Phone 1150E, WLAN Handset 2210/2211/2212/6120/6140.
The IP Phone 1210, IP Phone 1220, and IP Phone 1230 do not support IP
Call Recording.
