OK, I managed to get a proper protocol decoder added to my
closed-source sniffer. It looks like the new phones are
much pickier about the response packets.
1st up, the line_stat_res_message structure:
Packet captures against CCM show that lineDisplayName
should be , and that 60 bytes of packet padding is
So now the device registers and collects all of the
proper settings. The phone still does not work, throwing
errors for each of the response messages listed above.
I suspect that the same root cause applies, so I'll study
the CCM captures.
These changes DO NOT appear to break the older phones.
