[Freeswitch-users] docker / NAT troubles..

[Oz Mortimer]

HI,

I’m trying to get FS running in Docker, which largely was pain free (i know, i know, VMs, etc), but I can’t get my head around what is going on with RTP. Ive set ext-rtp-ip and it seems to be taking affect:

freeswitch at 7ad22635059e> sofia status profile internal

but when a call is placed i seems to be incorrect in the SDP

2016-04-06 16:29:49.011107 [DEBUG] mod_sofia.c:2353 Ring SDP:
v=0
o=FreeSWITCH 1459942605 1459942606 IN IP4 172.17.0.5
s=FreeSWITCH
c=IN IP4 172.17.0.5
t=0 0
m=audio 17584 RTP/AVP 8 101
a=rtpmap:8 PCMA/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=ptime:20
a=sendrecv

Shouldn’t the SDP reflect the Ext-RTP-IP ?

Im sure i’ve missed some sort of config setting or have gone snow blind!.
fs version is FreeSWITCH (Version 1.6.7 -14-d38d065 64bit)

Any ideas will be greatly received.
Thanks
Oz.
