[Freeswitch-users] advise to troubleshoot a call

[Philippe Le Toquin]

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...
