Hi Tristan Outbound jitter should not be ignored, it may even become worse on the way to the receiver. Most receiver (IP-phones) have a jitter buffer and will correct jitter up to 50ms (depending on vendors). I never experienced outbound jitter on a hard phone, but I have seen it up to 40ms on a soft phone (application on a PC). It turned out that the PC was heavy loaded with other tasks.

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?
