My FreePBX worked perfect for a view months. I could registrated extentions indoor and outdoor on wifi
and phone network 4G (Netherlands).
Strainge enough i only can registrate my extension on my indoor pc (using zoiper) with pjsip. My mobile
phone is using chan sip and i tried the GSwave and Zoiper app on a samsung android phone. I didn’t change
my network or freepbx settings.
Till now i know that if i stop/start the intrusion detection under the menu Admin -> System Admin i can
sometimes registrate my extension on my mobile phone again. As long as the network on my phone
not change from example 4g to 3g or wifi to 4g, it works.
PBX Firmware:10.13.66-13
PBX Service Pack:1.0.0.0
Asterisk Version: 13.11.2
I already use Dynamic DNS. Straing that the firewall blocks my 4g network. On 4G i can connect with a VPN to my
local lan.
Even if i put the freepbx machine in the DMZ of the firewall to test, it is not connecting anymore. Before it worked
perfect and in one time it stoped. Maybe some other solutions?
Where is the best location to whitelist my phones ip address?
