Filtering on Single Channels

You can filter on channels within a single call. For the Channel View table, the filter menu available with the right-mouse click depends on the channel you select. For Audio or Video channels, the menu has three filter options, Quick RTCP and RTP Channel Display Filter, Quick RTP Channel Display Filter, and Quick RTCP Channel Display Filter. You can create a display filter for the selected RTCP/RTP channel without having to first go to the filter window. For a data channel there is one filter option, Quick Data Channel Display Filter.

Call Playback

To get a subjective measure of call quality, you can listen to calls that contain RTP packets encapsulating PCMU or PCMA voice data (G.711 codec). The PCMU/ PCMA data is converted to wave file format and automatically played.

To playback a call from Multi-QoS, perform these steps:

1.Double click on a completed or active phone call which has RTP packets containing PCMU or PCMA data.

2.Select View Channel Details from the Call Detail View window.

3.The Channel Table appears. Right click on an audio channel and select

Playback PCMU/PCMA Data.

4.The Save As window prompts for the name of the file. The audio data is saved in a wave file format (.wav). After saving the file, the audio data is played.

5.A small dialog box appears while the audio data is playing. Press the Cancel button to stop playback.

Once the wave file is saved, it can be played from other media players.

Note that you will only hear one side of a complete audio communication. The complete conversation is composed of two channels and you are only listening to one of the channels.
