I thought I would give an update on my audio problem. <br>
<br>
No ground breaking news and a bit out of topic, so if you don't like
happy ending just ignore ! <br>
<br>
<br>
After restarting/resetting just about everything in my home
(guruplug, router,cable box, the phone adapter)<br>
I run out of idea and was getting really desperate...my next step
was to reboot the microwave oven just in case :)<br>
<br>
I then noticed while doing speed test on my line that the result
were most of the time good but sometime would go very low then
bounce back at the next test.<br>
<br>
I ended up calling my internet provider who after doing a few remote
test told me that my connection was rather flaky<br>
and that he was going to send me a technician the next day.<br>
<br>
They ended replacing my cable box who had a bad battery but the
technician also changed a few outdoor connectors<br>
that he said were about to give up and were most certainly the cause
of my problem.<br>
<br>
Since the phone is working great but more important the wife is
happy again!<br>
<br>
And I even get slightly more downlink/uplink that is actually
advertised<br>
<br>
Thanks all for the help and especially Michel Brabants who really
helped me understanding QOS.<br>

I didn't mean to imply it was something in Freeswitch. <br>

I am actually fairly certain it is not FS since it was working
fine for weeks on the same version.<br>

bisect. You can manually use git bisect to find out
which commit broke things for you. Check out Mitch

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.<br>

Hi Sean and Michel<br>
<br>
Thanks for your input.<br>
<br>
I did try the test and they came
back as all good saying I should get
good quality (my link 10Mbps
download, 1Mbps upload)<br>
The MOS score is reported as 4.2<br>
<br>
What I didn't find is what you
mention about 1, 3 or 5 lines. <br>
<br>
I will continue looking...

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.<br>
<br>
Kind regards,<br>
