Hi Team, Please help on the setting as proxy with kamailio sip server. Thanks On Fri, Jan 10, 2020, 7:33 PM Alexander Haugg <Alexander.Haugg@c4b.de> wrote:
OK,
I have the solution.
1. My think was to see the external candidate in the SDP. Freeswitch do that automatically, if the Client Registration from outside the local NW.
2. To force adding the external candidate, there is the channel var “include_external_ip=true”. For example -> originate {include_external_ip=true,media_webrtc=true}sofia/gateway/GW_SBC2_B2Bua/22100 &park
3. The srflx candidate will be set, if the internal port different from the external port (stun request). See the switch_core_media implementation for the candidate generation.
My questions are solved (at the moment ;-). My biggest problem was to understand the server stack vs. client stack behaviour for WebRTC.
Thanks a lot!

Does it work with a manually entered IP?

Hi,
if I set the parameter „<X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=stun:stun.freeswitch.org"/> “ in the vars.xml and use this variable $${external_rtp_ip} in the SIP Profile, then the Ext-RTP-IP show the real external IP.
I think, that’s OK.
But I miss the srflx candidate in the sdp.
I tried to experimental with the apply-candidate-acl (rfc1918.auto, any_v4.auto, wan_v4.auto), but nothing works.
What’s wrong?

Hi,
I’d read the manuals and configure my sofia profile to work with the external IP in the ext-rtp-ip setting.
<param name="stun-enabled" value="true"/>
<param name="stun-auto-disable" value="false"/>
<param name="ext-rtp-ip" value="stun:stun.freeswitch.org" />
The Freeswitch is started with the parameter –nonat
In the pcap trace is no STUN request visible.
I try to restart the Freeswitch, restart the profile, do an outbound call, but there is no STUN request.
If I try to get my external IP via the CLI cmd “stun stun.freeswitch.org”, then works it successfully.
The status output of the profile is:
