You can build a 2 or 3 port VLAN, and use it to run your internet line into,
and then another port out to your ingate.  Port mirror either port to get
the traffic ahead of the ingate, or use the third plug for your wire shark
device.

Pull a Wireshark capture before the ingate during an affected call.  Pick an
RTP stream and analyze the stream.  It will allow you actually listen to the
audio of the call before it enters your network.  If the call quality is OK,
pull the capture from the ingate.  Then pull one from inside the network.
Easiest way to figure out where the problem lies.

If you have a layer 3 switch, you can port mirror the port the phone is on
so you can get all data going to the phone.  To grab packets before your
ingate, use a hub, not a switch to make sure you get all traffic.

If it were me I would run a packet capture (wireshark)....not look at logs.



Logs and sipx-trace files are great for signaling issues (transfers, failed
calls etc) but they do not log much at all about the RTP streams.


So it simply wont log issues with latency in the voice.  



If you capture the traffic via wireshark you can then analyze the RTP
stream.  It will even select and mark packets where it thinks it causes
voice issues.


And I see your using an ingate which has a built-in packet capture feature
which is a really nice.  So you can capture packets at the ingate and see
where the issue is at.


Doing a capture at the switch level via a port monitor is good too, helps
you determine if the issue is inside or outside the network.
