Ok, I’m little confused with what ports is what
I’m trying to understand whats needed. In my Asterisk host I opened firewalld for 5060 (SIP protocol) and range 15000-15100 for RTP. From what I understand, each active channels will use 2 ports from RTP pool. I don’t expect more than 50, so I narrowed it down to this range. Same ports forwarded through the company router to outside world.
Now, I was setting up Cisco phone following those instructions and got little confused on what I’m doing and why. Phone installed at home, behind another router. (everything works, I just want to understand)
Phone have it specified that SIP port 5060.
Why do I need so specify on proxy: mydomain.com:5060 ?
Also, there is a recommendation to start with number and go up for each consecutive port. Next phone will be 5061 and so on. How are those all ports relate to each other?
Also, I had RingCentral phone before and they wanted ports “triggered”, not “forwarded”. Is there some simple instructions or article on how this works and what all of those terms mean?
