I once looked into this a couple of weeks ago and I didn't find any way to
enable any kind of notification from modem when the peer hangs up, but very
likely I haven't been looking close enough (perhaps +CPI:.. ?). Instead I added
a timer that fires when there's no +CRING for two seconds and notfies gsmd
clients. The commit id was aba18c571f07e8467dac488a3ca0697002628d9c in the gsmd
tree at http://folks.o-hand.com/andrew/gsmd.git, it also fixes a couple of other

Tick, perhaps you could comment on whether you think the time out should be
implemented on the gsmd side or the client side?

The version of aba18c571f07e8467dac488a3ca0697002628d9c on
is dealing with RING timeout but not +CRING timeout.

This patch is committed as R3572.

It works for gsmd with AT+CRC=0 && without AT%CPI=2 or 3
Currently gsmd use the %CPI information to tell if a call is disconnected.

A timeout scheme of +CRING is still needed if another modem, without %CPI
support, is used.
