<div dir="ltr"><div>Hello all!<br><br></div><div>Thanks for the recommendations on upgrading to FS master, (Assuming that is 1.6.2?) and using the new Jitter Buffer and OPUS codec. Unfortunately, after researching and working with our ATA vendor OBI, they do not support OPUS. So that has me form a few more questions on this issue.<br></div><div><br></div><div>1) Is there any documentation on the new Jitter Buffer being used?<br><br></div><div>2) Is there any reason to believe that upgrading from our current Free Switch Version 1.4.18 to 1.6.2 would fix the issue with the current codec of g711, even tho I can not use opus?<br><br></div><div>3) Below is the real issue that I am trying to fix:<br></div><div><br></div><div>obi200------------> fixed wireless --------> FreeSwitch ------PSTN</div><div><br></div><div>Call
Quality issues are mainly reported by the end user on the PSTN
network. Users report that the calls are cutting in and out but our
users on the obi200 side hear them perfectly. Any ideas on settings to
try to optimize in this situation?<br><br></div><div>I know that it is a network related issue, with high jitter, however I know there must be a fix as other VOIP providers can ride the same network path and have no issues at all.<br><br></div><div>4) Main reason for not just upgrading is that I am using fushionPBX, and they do not yet support 1.6.2, and also trying to figure out an actual upgrade plan so that I do not loose all the customers voicemail's, VM greetings passwords and such. <br><br></div><div>Any help is greatly appreciated with what direction I should go.<br><br></div><div>Thanks!<br></div><div><br></div><div>Josh</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Nov 13, 2015 at 9:45 AM, Brian West <span dir="ltr"><<a href="mailto:brian@freeswitch.org" target="_blank">brian@freeswitch.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">We probably need to wipe confluence clean of the incorrect jitter buffer docs now that its been completely rewritten in the past few months.</div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Nov 12, 2015 at 4:06 AM, Ola Bäckström <span dir="ltr"><<a href="mailto:Ola.Backstrom@loxysoft.se" target="_blank">Ola.Backstrom@loxysoft.se</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal">Hi Josh,<br>
<br>
Use FS master, it has a new audio Jitter Buffer.<br>
<br>
Then you can use Opus with this setting in the codec config:<br>
<param name="use-jb-lookahead" value="1"/> . <br>
The other side must be sending FEC so you could profit from it.<br>
<br>
<br>
You can enable the Jitter Buffer in the dial plan:<br>
<action application="set" data="jitterbuffer_msec=2p:25p:"/><br>
And then enable PLC :<br>
<action application="set" data="rtp_jitter_buffer_plc=true"/><br>
<br>
Regards,<br>
Dragos<br>
