I have searched everywhere online but i haven’t been able to fully understand this, hopefully one of you freepbx gurus can help me.
Using hosted FreePBX 18.104.22.168 with asterisk 15 and polycom vvx310
To my understanding keeping the default 5060 port is not advisable due to it always being probed. So I try changing ports under Settings>Asterisk SIP Settings>Chan SIP Settings>Advance General Setting>Bind Port to 45xxx and tls bind to 44xxx. but i run into random intermittent registration issues when the office has power surges. in addition i do configure the service providers dashboard and change the settings to point correctly to the server as well as the phones, for example SERVERIP:45xxx. what is weird is that registration seems to be a hit or miss or it will register and have no inbound or outbound audio. in this case the systems were set and working for about 3 to 4 weeks except until the recent power outage which the phones would not reconnect to the server until i reverted all ports to 5060.
Is there something im missing? isnt the bind port the same as the registration port? or is there another setting im suppose to change?
