<br>
we have the following problem:<br>
<br>
Our Freswitch is behind NAT. We are sending faxes to a SIP provider.<br>
Dependend on the destination number, the faxes are received or not.<br>
Faxes are always sent via the same SIP provider and the same dialplan,<br>
but I expect, they may be routed differently via other, subsequent SIP<br>
providers.<br>
<br>
Regarding the SDP I can see, that the c-line does contain the our<br>
external IP, but the o-Line does contain the local IP in the<br>
unicast_address field.<br>
We are routing the call via a defined gateway in the external profile,<br>
which has external_sip_ip set and external_rtp_ip set.<br>
Dialplan is:<br>
<action application="export" data="t38_passthru=true"/><br>
<action application="set" data="proxy_media=true"/><br>
<action application="bridge"<br>
data="sofia/gateway/QSC/<a href="mailto:06912345678@sip.qsc.de">06912345678@sip.qsc.de</a>"/><br>
<br>
Here is the SDP<br>
====================================<br>
v=0.<br>
o=FreeSWITCH 1037989557 1037989558 IN IP4 192.168.206.241.<br>
s=FreeSWITCH.<br>
c=IN IP4 212.xxx.xxx.106.<br>
t=0 0.<br>
m=audio 12056 RTP/AVP 0 8.<br>
a=rtpmap:0 PCMU/8000/1.<br>
a=rtpmap:8 PCMA/8000/1.<br>
a=maxptime:240.<br>
====================================<br>
<br>
I suspect, that the following SIP providers may have a problem with the<br>
o-line with the local IP.<br>
So - Is there any way to control this? E.g. via Dialplan variable?<br>
<br>
ACL also seems to be fine<br>

<br>
I see the same behaviour also in<br>
<a href="https://freeswitch.org/jira/browse/FS-5909" target="_blank">https://freeswitch.org/jira/browse/FS-5909</a> "ext-xxx-ip ignored with<br>
proxy_media turned on"<br>
There is a link for a patch, which is no longer available. Did this go<br>
into the main release? Does anybody have this patch?<br>
<br>

With kind regards<br>
