I recommend that you get a pcap of such a conversation and
analyze it in Wireshark. See if the lag shows up in the
analysis or not. That will at least give you a clue as to
where the issue is. (Compare the recording on disk with the
playback in Wireshark. Note: you'll need the call to be
g.711 for this to work.)<br>

<pre>No, the callers do not notice anything, they hear each other without problem.
One party is on the local network where FS is, and other is outside.
But as they do not notice this problem, i think the problem is at the recording. I think.
