The model#s are wrong all over the original wiki article, but no matter. There's no "Show model" button, but the "Pick Device Template" button opens a window defining 7970 phones:
you are right with that. Thank you for pointing that out.

with ranges of MAC addresses ("Range of MAC" / "From" / "To").
yeah, thats the right form.
However, the "Registering" message with moving time wheel stays on screen, and the SEP<MAC>.cnf.xml and CTLFile.tlv status messages keep showing. Those messages are probably related, and indicate at least some instability in the installation.
it bitches about the cnf.xml? Hmm, please tell me the firmware type and version from the phones menu.
I have to get some christmas presents now but we can step throught that in the evening.
After checking the version we can debug it via the asterisk command line.
best regards,
