Hi Bret,
Just a heads up: it is customary to not top-post on open source mailing
lists. So please don't do that in the future ;)

It provides a Handsfree Gateway service. I was wondering if it doesn't send any
callsetup indicators because it is not cellular. Otherwise, you're probably
correct that it's not a proper device.
HFP 1.6 does explicitly state that callsetup is required in the case of
an outgoing call being dialed from the HF. There is no equivalent
sequence diagram for the call being dialed from the AG, however this is
mandated by TR002. So from that standpoint you're a little bit unlucky
in that your device is not really compliant.
Just quickly glancing at the product page, it does indicate mobile phone
compatibility. Maybe the HFP part is only meant when you're using it
with a mobile network.
That said, you can try to hack around this a bit by detecting the call=0
-> call=1 transition regardless of callsetup, but you'd still be missing
any sort of dialed number information, etc. Not sure how really useful
oFono would be for this usecase.
Regards,
