So this very much depends on the modem. Most (sane) modems return an OK final response to the ATD when they start dialing. Some will then accept regular AT+CHLD commands to terminate the outgoing call, others have a vendor specific command for doing so. The broken ones return an OK/BUSY/NO CARRIER for the ATD only when connected/busy/timed out, in which case there's no standard way to abort that I know of. This might be an area where I'd like to hear some feedback, whether an additional dial_abort function pointer is required in the voicecall plugin. However, the entire 27.007 spec for voice calls is utterly broken, there's no way to get it right. If your modems support vendor extensions for call control, in particular call state reporting, I suggest using those. I expect all major vendors have implemented such features in their modems. I don't expect the reference implementation to be used in practice, as it is too battery inefficient. > > > Create the call: > $ dbus-send --print-reply --system --dest=org.ofono /modem1 > org.ofono.VoiceCallManager.Dial string:"+358000000000" string:"default" > > The following do not work as the /modem1/voicecall01 does not exist: > $ dbus-send --system --print-reply --dest=org.ofono /modem1/voicecall01 > org.ofono.VoiceCall.Hangup > Error org.freedesktop.DBus.Error.UnknownMethod: Method "Hangup" with > signature "" on interface "org.ofono.VoiceCall" doesn't exist > > $ dbus-send --system --print-reply --dest=org.ofono /modem1/voicecall01 > org.ofono.VoiceCall.Busy > Error org.freedesktop.DBus.Error.UnknownMethod: Method "Busy" with > signature "" on interface "org.ofono.VoiceCall" doesn't exist So you can only use this one on an incoming or waiting call. > > > The VoiceCallManager.HangupAll does not work either: > $ dbus-send --print-reply --system --dest=org.ofono /modem1 > org.ofono.VoiceCallManager.HangupAll > Error org.ofono.Error.InProgress: Operation already in progress Regards, -Denis _______________________________________________ ofono mailing list [email protected] http://lists.ofono.org/listinfo/ofono
