Hello Patrick,<div><br></div><div>there are the channel and dstchannel properties of the CHANNEL function, indicating that the channel is some kind of virtual connection between the sip phone and the sip provider, so it seems not to be for legs or at least the output values are already a combination of both legs. (I also would find it more intuitive to have 2 legs and values for those instead of one single value for 2 legs, but lets wait to find out, how to interpret those things).<br>

Hello all,<br>
<br>
I need some help understand the values of the CHANNEL function, e.g.<br>
<br>
txploss // local packets loss<br>
rxploss // remote packets loss<br>
txjitter // local jitter<br>
rxjitter // remote jitter<br>
<br>
<br>
My main problem in understand is that a CHANNEL has two nodes (sender<br>
and receiver), while a typical setup includes at least 3 nodes:<br>
SIP phone - Asterisk - SIP Provider ( -> each is a node)<br>
<br>
1) So e.g. txploss, is it<br>
- what is lost between SIP phone and Asterisk<br>
- what is lost between Asterisk and SIP Provider<br>
- or probably both?<br>

I would assume that those statistics apply to a leg and not an end-to-end connection. So in your example I would assume that a txploss value is determined for the leg between the SIP phone and the Asterisk server and another txploss value is determined for the leg between the Asterisk server and the upstream SIP provider.<br>
<br>
Interesting stuff. If you figure it all out, please update this thread (and possibly the wiki).<br>
<br>
Regards,<br>
Patrick<br>
