Vox works fine.(with no receive audio) (very useful feature to my setup)
in P mode(no vox), when dialin *6 (6=cop,6) it does not activate PTT
until timeout or hangup.
When i enable debug in rpt, and dial first *6 from sip
rpt detects *6 from sip and prints
...
@@@ action cop,6
...
<<radio tx on >>
and ptt activates and so on... (i think "radio tx on" is from chan_usbradio)
when i dial second *6 from sip (to deactivate)
it prints same @@@ action cop,6 but does not print << radio tx off >>
when i dial randomly *,6,# numbers from sip in random order many times
i occasionally get
<< radio tx off>>
<< radio tx on>>
always in pairs so that PTT remains on.
in S mode i can't activate PTT at all.
dialing * from sip i get
<< radio tx on>>
<< radio tx off>>
always in pairs so that PTT remains off

you are right it is chan_usb radio that reports DTMF tones

i'm not using CTCSS at all

no receive audio at all.
i started asterisk always fully when tested (not reload) and i have
never heard
receive audio
