Outbound RTP analysis and Jitter

[Tristan Leask via Wireshark-users <wireshark-users () wireshark org>]

Hi all,

I have a capture file that has been taken from a server running FreeSwitch.  It shows all the coms between it and 
everything else, including the SBC, which is what I am interested in.  The capture has been taken at the FreeSwitch 
server and not the SBC.  If I run an RTP stream analysis, it shows me all the RTP streams that are in the capture.  I 
am specifically looking at one stream which has the source address as the FreeSwitch Server and the destination as the 
SBC, so in my view, this is an outbound stream.

This outbound stream has a high max jitter value that is outside acceptable ranges.  As this is an outbound stream, how 
can this be the case?  I though jitter can only be calculated for inbound streams?  What is jitter on an outbound 
stream?  Can this high value be ignored and not be the source of poor outbound audio quality?

Thanks

Tristan
