Are you sure that there are no peer to peer or other network programs competing for outbound bandwidth when she is talking? Does your router have any way of prioritizing SIP and RTP or penalizing other protocols? Sent from my iPhone On 24/04/2013, at 00:43, Michael Collins <msc@freeswitch.org> wrote: pcapsipdump ftw! Check it out: http://wiki.freeswitch.org/wiki/Packet_Capture#pcapsipdump It gets pcaps for you and separates each call into its own file with both signaling and media. Find the pcap with a bad phone call and open that one up in Wireshark for analysis. -MC On Tue, Apr 23, 2013 at 6:30 PM, Philippe Le Toquin <philippe@ppmt.org>wrote:
Hi Sean and Michel
Thanks for your input.
I did try the test and they came back as all good saying I should get good quality (my link 10Mbps download, 1Mbps upload) The MOS score is reported as 4.2
What I didn't find is what you mention about 1, 3 or 5 lines.
I will continue looking...

RTCP provides you normally with statistics that can help you. I didn't check it in freeswitch yet, but there is an option to enable it (not standard apparently?) in the profile. One step further is rtcp-xr which can provide mos-score, but with all of this, the receiving endpoint should also support this.
Kind regards,
Michel

Philippe,
The audio is sent through UDP packets, not TCP packets. The main difference is that if UDP packets are lost in collisions or congestion, they are not retransmitted. What you are describing COULD be completely explained as internet congestion.
I would test with some application that loads her network link down. One example is http://www.onsip.com/tools/voip-test
Try the various levels (1 line, 3 or 5 lines) and see how a call with her reacts when the test are run. That will at a minimum rule out congestion on her local internet connection.
HTH,
Sean

Hello,
Recently I (well my wife) is having voice problem when she is on a call.
Typically she can hear people but they can't
The problem is that it is not all the time and when it happens it last a few seconds then all back to normal... then later on it happens again.
I am still in the process of trying to find if there is a pattern in the problem but I would like to be able to look at the log from FS.
What would you recommend to be able to look at the log (what debug level).
Any tips to make it easier to identify an issue in the log (like message to look for?)
Thanks
Philippe
