What ports are needed to make Zulu 3 work the best.
I look at https://wiki.freepbx.org/display/PPS/Ports+used+on+your+PBX
Says Port 8002, but maybe your RTP ports. No explanation on why “maybe” they either need to be open or not, or is it just if you use chan_sip instead of pjsip.
Q) In what cases will I need to open the RTP ports?
There is another port regarding Zulu Stun server and how port 3478 may also need to be open.
When I first looked at Zulu it looked as everything just ran over 8002 securely, now we are looking to open the RTP ports which is not encrypted.
I just want to know what need to be done to make Zulu work. Opening ports up internally is not as scary as when we open the the public. I’m guessing many of us are looking at Zulu to give the sudden increase demand on teleworking an easy to use and implement solution.
