Hi,
your use of isdnphone looks OK to me; however, the error you are getting
is a ...feature of isdnd: in usr.sbin/i4b/isdnd/fsm.c, table state_tab[]
defines what events are accepted when the call is in which state -- and it
does not (basically) accept more than one hangup per call, be the hangup
local or remote. Specifically it does not allow for the situation where
_both_ ends hang up the call, since that generates two disconnects, and
the latter pulls the entry to illegal state (from which it does not
recover). Unfortunately in telephony applications, this is a relatively
common phenomena.
You might want to mofidy the said table as I have: change the {F_ill,
ST_ILL} in the ST_IDLE column for EV_MDI into {F_NcNa,ST_IDLE}, it makes
isdnd accept a remote disconnect on an already disconnected call without
invalidating the config entry. It already does so for a local disconnect
(EV_DRQ) -- so you can actually do multiple local hangups even to a
disconnected entry.
Br,
Juha
