      The caller is not originating from our FreePBX instance, and is spamming the device directly.

      Wouldn't that seem to indicate that blocking all traffic but the SIP traffic from the PBX would resolve the issue of unsolicited calls?

      I guess I might have the wrong end of the stick... are the phones getting calls that are NOT from the PBX? Rather than the PBX having anonymous calls routed through it?

      That's how I read it. But that brings up another issues, shouldn't the registration process prevent this from happening?

      No registration used when there is no PBX involved.

        So the phone was just accepting all SIP requests. Glad you fixed it @RamblingBiped .

            Yeah, that's actually pretty standard. You can just throw a bunch of phones on a network and dial each other via IP. No one does it, but nearly all phones support it out of the box.

              Well that sucks. Look for a setting called something like "Anonymous SIP".

                How about "Allow SIP Trust Server Only"?

                  Is there a direct number associated with the phone that they could be calling directly instead of routing to it?

                    No, I've actually got the DID/inbound route for dialing the phone directly tied to a Ring Group that rings a pair of phones; that is one of the reasons I know it is being dialed directly.

                      Not only that but a DID would most likely be going through the PBX.

                        That sounds good.

                          A DID points to the PBX and is stripped out before going to the phones. DIDs don't pass through the PBX.
