No need to worry about &quot;L16&quot; codec - that&#39;s talking about signed linear 16 bit audio, i.e. uncompressed, raw audio. If you&#39;re talking directly to FreeSWITCH, for example when you call voicemail or call an IVR, then the FreeSWITCH side will definitely be &quot;L16&quot;. However, if you are connecting through to another device, like another telephone, then you&#39;ll see codec negotiation.<br>
<br>Remember: when audio passes through FreeSWITCH it always gets decoded (unless you&#39;re using proxy media, but don&#39;t do that) and re-encoded, so you&#39;ll always see references to L16 which is the &quot;decoded&quot; audio. The primary reason for decoding everything is that FreeSWITCH can then do fun stuff like eavesdropping, mixing audio, conference calls, etc. You can&#39;t (easily) mix encoded audio.<br>
<br>So... your issue is most likely not with a codec mismatch but rather timing on the VM. I&#39;ll defer to those who know more about VMs and such.<br><br>-MC<br><br><div class="gmail_quote">On Thu, Mar 22, 2012 at 9:23 AM, Bzzz <span dir="ltr">&lt;<a href="mailto:lazyvirus@gmx.com">lazyvirus@gmx.com</a>&gt;</span> wrote:<br>

Hi list,<br>
<br>
I&#39;m testing FS w/ twinkle, put iLBC as first CODEC and don&#39;t follow<br>
far end CODEC preference.  All extensions have proxy_media set.<br>
<br>
When I call the VM (*97) I get a very choppy audio.<br>
<br>
FS log says: [DEBUG] switch_ivr_play_say.c:1306 Codec Activated L16@8000hz 1 channels 30ms<br>
when twinkle says: ilbc<br>
<br>
I guess that the source of my problem, but how can I change that for<br>
FS to switch to iLBC? (I already modified CODECs names &amp; orders into<br>
conf/vars.xml to set iLBX@30i first, and twinkle is also set to 30ms)<br>
