Bumping the above post containing a couple of questions (edited in the above quite from the original for brevity and clarity).I have finally been able to receive incoming calls to my Signalwire DID registered to my IncrediblePBX CentOS 6.9, "13.13" instance.
I have Enable TLS = yes and SSL Method = sslv2. That's correct, or necessary? It works...
I can seemingly ONLY pull this off if I set Allow Anonymous Inbound SIP Calls = yes and Allow SIP Guests = yes. I don't ordinarily ever do that. Is there a way around this that I might be missing? Otherwise, the PBX complains "WARNING,"Rejecting unknown SIP connection from [applicable Signalwire IP address]."" This happens even though I have added all Signalwire-related IP addresses to IPTables.
The PBX will also complain "WARNING[C-00000000] chan_sip.c: Declining non-primary audio stream: audio 16662 RTP/AVP 0 101 13" even though the Signalwire and PBX codec settings are [I believe, and have checked] identical.
These are the IP addresses, obtained after asking in the Slack channel, that I have added to IPTables:
