recording's channels shifted
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.

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.) -MC On Thu, Sep 20, 2012 at 2:03 PM, Tóth Róbert <trob@freemail.hu> wrote:

I've ran into this before, and it ended up being feedback from the handsets on both sides of the call. It doesn't really bother us now that we know what it is. -BDF On Thu, Sep 20, 2012 at 5:24 PM, Michael Collins <msc@freeswitch.org> wrote:
