<div dir="ltr">Links to some sip traces WITH the freeswitch logs in all these cases would be most helpful, Since your FreeSWITCH is behind nat, Are you setting the ext-sip-ip and ext-rtp-ip along with the local-network-acl? (Also you must prefix the ext-*-ip elements with autonat: if you wish to dynamically lie about the IP depending if the endpoint is behind nat with FS or outside the nat ie thats what local-network-acl is for)</div>

<br>
I am trying to figure out why I see what I see.<br>
<br>
When I make a call using the same codec (say, PCMA/8000 on both sides), FreeSwitch rewrites the RTP stream's IP address and port for me. That I like, since my FreeSwitch is behind NAT.<br>
<br>

2014-07-16 12:32:36.995906 [INFO] switch_rtp.c:3738 Auto Changing port from <a href="http://9.10.11.12:12345" target="_blank">9.10.11.12:12345</a> to <a href="http://13.14.15.16:41730" target="_blank">13.14.15.16:41730</a><br>
<br>
Now, when I try to use two different codecs, this behaviour stops.<br>
<br>

2014-07-16 12:35:36.495902 [INFO] switch_rtp.c:3738 Auto Changing port from <a href="http://1.2.3.4:4042" target="_blank">1.2.3.4:4042</a> to <a href="http://5.6.7.8:4042" target="_blank">5.6.7.8:4042</a><br>
<br>
The other line is missing and ngrep reveals how FreeSwitch stubbornly sends RTP audio to the wrong port and IP address.<br>
<br>
Further testing shows:<br>
<br>
PCMA -> PCMA: IP/port is rewritten<br>
SILK -> PCMA: IP/port is *not* rewritten<br>
GSM -> PCMA: IP/port is rewritten<br>
Speex -> PCMA: IP/port is *not* rewritten<br>
<br>
How can I have transcoding *and* RTP IP/port rewriting work at the same time, please?<br>
<br>
Is this a per-codec thing?<br>

Change is good. Granted, it is good in retrospect, but change is good.<br>
