VoIP analyzer allows you to save one or several VoIP data objects
to a container file in NVF format. Unlike common capture files, NVF
does not contain captured data packets. Rather, this is a set of
VoIP object(s) stored in a single file. NVF files are instrumental
when you want to save a VoIP call with all the related streams for
future analysis.
VoIP objects that can be saved to NVF files are:
·SIP
Sessions
·H.323
Sessions
·RTP
Streams
To save an object to a NVF file, select one or several objects in
the VoIP analyzer lists, right-click to open the context menu, and
select the
Save Objects As…
menu item.
SIP or H.323 sessions and respective RTP streams (if any) will be
saved to a file. However, if you choose to save the RTP stream, the
respective parent SIP or H.323 sessions will not be saved.
You can load the saved NVF file into
VoIP Log
Viewer
window.
