Thank you, the absolute codec string addition worked. My original dialstring was &lt;action application=&quot;bridge&quot; data=&quot;sofia/gateway/<a href="http://voip.ms/1$1">voip.ms/1$1</a>&quot;/&gt;, BTW (where <a href="http://voip.ms">voip.ms</a> is imported by the external profile). I just have one more unrelated question about voice sample times. If one leg is using 20ms and the other 30ms, does freeswitch introduce a buffer and if so, how much delay is it?<br>

try putting your dial string to your provider like this:<br>

&gt; I have the following setup:<br>
&gt; <a href="http://voip.ms" target="_blank">voip.ms</a> &lt; (external profile) &gt; freeswitch &lt; (internal profile)&gt; my devices.<br>
&gt; On my internal profile, the only inbound and outbound codec I allow is iLBC<br>
&gt; (I tried 20ms and 30ms), and on my external profile the only inbound and<br>
&gt; outbound codec I allow is PCMU. All my internal settings are compatible with<br>
&gt; the devices that I&#39;m using, and everything works well when I call from<br>
&gt; outside in, and freeswitch now correctly transcodes from PCMU to iLBC.<br>
&gt; However, when I call from my internal devices to outside, the iLBC codec is<br>
&gt; offered on outbound leg B, not PCMU like I have on my external profile.<br>
&gt; Looking at wireshark voip call flow, my machine is sending iLBC to <a href="http://voip.ms" target="_blank">voip.ms</a><br>
&gt; and <a href="http://voip.ms" target="_blank">voip.ms</a> is sending me PCMU RTP.<br>
