How to extract VoIP and video calls from your GigaStor
VoIP and videoconferencing calls can be extracted from a GigaStor if you know the approximate time the events
occurred.
Prerequisite(s):
You must understand how to select a time frame from your GigaStor. See ../observer/
voip_and_video_sip_extraction.html .
Note:
This process is only compatible with SIP data.
Locating and extracting SIP-based voice and video data from your GigaStor is a straightforward task. All of the
SIP setup and teardown packets are extracted along with any payload, such as audio and video, to ensure you
retrieve complete sessions. This includes all person-to-person audio calls and videoconferencing as well as
conference calls and conference video where multiple endpoints are present. And
endpoint could be a person
holding a handset, wearing a headset, or a line that is open for hold music or for recording.
To extract VoIP and videoconferencing calls from your GigaStor:
1. Select a time frame you want to analyze.
2. Click the Update Reports button to get the latest data from the time frame selected.
This step is unnecessary if Auto-update GigaStor chart on statistics tab or selection change is enabled in
the GigaStor settings. See ../observer/non_gigastor_specific_settings.html .
3. Click the Analyze button.
4. In the
Analysis Options
section, choose VoIP and Videoconferencing calls by SIP tag. Click the
Settings
option and choose your call search criteria.
