Audio (FreeSWITCH) not working with external IP

[Floh]

Hi,
I setup a bbb-server with FreeSWITCH (until now we used Asterisk).
Unfortunatelly audio is not working if I try to access BBB over
internet (with external IP).

I tried with internal address, audio works fine after set back IP
address with this command: 'bbb-conf --setip <InternalIP>').

I did following steps:
- bbb-conf --setip <ExternalIP>
- modified /usr/share/red5/webapps/sip/WEB-INF/bigbluebutton-
sip.properties
sip.server.host=111.222.33.44
111.222.33.44 = external IP
- define firewall rules + NAT-Portforwarding following ports:
TCP 80
TCP/UDP 1935
TCP/UDP 5070
TCP/UDP 15000-16383
TCP 9123

Now I entered a room. There I pressed headphone icon which means to
enable voice. Then nothing happens. There I espect a dialog from flash
which ask for permission for using microphone but nada.

What could it be wrong?

I did 'bbb-conf --check' with following output:
>>>>>>
root@bc01-conferenceDev:~# bbb-conf --check

Hi Floh,

Change your sip.server.host back to your internal IP and following the
instructions here for providing external access to your BigBlueButton
server.

I already read that documentation. Ports are forwarded as described in doc. But I didn't the following step:

Internally, BigBlueButton must be able to call external.host.org to make API requests. In this example, if the internal BigBlueButton server is at 192.168.10.198, add the following line to /etc/hosts.

192.168.10.198 external.host.org 

 

I don't have domain-name for that machine. Just a external IP. Does it matter?

Yes, you need a domain name; otherwise, it won't work. You can easily
create one for your external IP address at

thank you. Now it works fine with domain name. I didn't think about dyndns before.
