One might think that. However, the basic network stuff looks to be working OK.

Twinkle on the same machine works just fine, as does Blink on a Mac on the same LAN.

I've verified that my iptables are flushed, and tried connecting directly to the cablemodem (no firewall, not NAT, public IPv4 address), to no effect.

Just Wiresharked the session, using the working LAN interface as my capture source, and a filter of "port sip". Very interesting. It shows the packets being generated from Blink, and the expected non-responses from the server end. However, I'm periodically getting a 4-byte packet on my SIP port back from the pbxes.og address, containing a payload of 0x00000000 -- that is, four zeroed bytes. I'll have to set up another layer of network so I can see if those packets are actually "on the wire".  The null packets might be an artifact of an earlier Twinkle session I ran on the machine.
