How to hangup outgoing call, before terminating end answers?

How to hangup outgoing call, before terminating end answers?

Hi,

Currently when a call is created with Dial method the object path for
the call (e.g. /modem1/voicecall01) is returned only after the
terminating end has answered to the call. So is it possible to Hangup
the call from the originating end before terminating end answers the call?


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


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,
Marko

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.

So you can only use this one on an incoming or waiting call.

It's normal if the voicecall01 didn't be setup

Busy only for waiting and incoming call

It should be a bug if you use real modem

In phonesim the outgoing call be accepted quickly so can't find this issue.

I had same problem with a "phone" in real network; I assume its phone limitation before.

FWIW, I just tried this on my G1 and it worked fine:

localhost:~/ofono# !109
dbus-send --system --print-reply --dest=org.ofono / org.ofono.at.Manager.Create string:"dev:/dev/smd0" string:"at"
method return sender=:1.0 -> dest=:1.1 reply_serial=2
   object path "/modem1"
localhost:~/ofono# dbus-send --system --print-reply --dest=org.ofono /modem1 org.ofono.VoiceCallManager.Dial string:"617501XXXX" string:"default"
method return sender=:1.0 -> dest=:1.2 reply_serial=2
   object path "/modem1/voicecall01"
localhost:~/ofono# dbus-send --system --print-reply --dest=org.ofono /modem1/voicecall01 org.ofono.VoiceCall.Hangup
method return sender=:1.0 -> dest=:1.3 reply_serial=2

Hangup returned successfully prior to the other end picking up.
