@jlizzotte04 @Stewart1 please help because I think that I will loose my minds soon.
only way to get inbound calls is with “Allow Anonymous Inbound SIP Calls”
This is my connection string (but again to place calls from freepbx to outside it’s working )
and for outgoing
Trunk it’s defined as chan_sip .
I guess that I am using registration . I guess that credentials and config string it’s completed well since outgoing ok.
I was guessing / suspecting / digging around NAT configuration . My little NTW setup looks like
Internet (pbx agents) -> pfsense ->192.168.1.23 ETH1 ->FreePBX
SIpTrunkPRovider-> ONT box -> 192.168.32.110-> ETH0->FreePBX
I have declared 2 static routes toward my SIP trunk provider. all ntw setup it’s detected like in picture below in settings>asterisk sip settings.
Thank you for any suggestion I am simply clueless.
