I previously posted the theory in how to answer a call. I've now got this codified ... just not working git clone https://vcs.maemo.org/git/theonering theonering/hand_tests/dbus_signals.py or https://garage.maemo.org/plugins/ggit/browse.php/?p=theonering;a=blob;f=hand_tests/dbus_signals.py;h=d80ba2f3c2c2d4518dab2252e535a2b4d12e76b7;hb=19d650012308b89c7e15135fb849c6ca9f02ce99 This code 1. Listens on DBus for new channels (NewChannelSignaller) 2. Creates telepathy-python objects out of the new channel and its connection (NewChannelSignaller) 3. Filters out all channels except StreamedMedia (Manager) 4. Requests various data needed for Step 5 (AutoAcceptCall) 5. Judge whether it is an inbound or outbound call (AutoAcceptCall and Manager) 6. Add all the pending users to the call (AutoAcceptCall and Manager) Step 6 should be what answers the call according to http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Channel.Type.StreamedMedia.html I've played with dbus-monitor. All 6 steps execute correctly, it just doesn't cause anything to happen. This was tested with SIP calls on Empathy 2.26. I'm probably going to take another break from working on this. What I've got working so far can help me resolve one issue (poll for new GV voicemails after the user rejects/ignores a call) but not another (auto-accept GV callbacks). I don't know if this is still relevant for anyone but I thought I'd at least share.

Re: Telephone API question - answering a call.
This is something I'm also very interested in. With The One Ring (a GV plugin for RTComm) there is a usability issue that could be solved by auto-pick up of calls. Unfortunately I'm busy with lower level details at the moment and don't have the time to look into it. I'm unsure how much experience you have with telepathy but I thought I'd write down some theory and suggestions to get you on the right track. On an incoming call, the "Connection Manager" (Sofia == SIP, Spirit == Skype, can't remember the name of GSM's) creates a DBus object called a StreamedMedia channel. This channel also implements an interface for Group which allows multiple contacts (yourself being one of them) to be associated with it with waiting lists for being accepted into the channel. See http://telepathy.freedesktop.org/spec/ http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Channel.html http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Channel.Type.StreamedMedia.html http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Channel.Interface.Group.html It seems they are drafting a new channel type and interfaces for this, so I don't know how long this will be relevant (at least for Maemo 5 I would guess) http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Channel.Type.Call.DRAFT.html In my repo I have a hand test which gives examples on how to be a client, to be the one making calls https://garage.maemo.org/plugins/ggit/browse.php/?p=theonering;a=blob;f=hand_tests/generic.py;h=3d83a79e7d1630b1fc38b47490bb7c0abd1ac918;hb=bc1000e7265476c358100a19fe554ff2a1a00d315e2e My guess is you would need to monitor for the NewChannel signal from the Connection http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Connection.html This will give you notification of dbus objects including their object path and their channel type (if Streamed Media). For your to programmatically determine who initiated the call and to pick up, I recommend this part of the Streamed Media spec """ Incoming calls should be signalled as TargetHandleType = Contact, TargetHandle set to the remote contact, with the local user in LocalPendingMembers; to accept the call, AddMembers can be used to move the local user to the group's members. When the local user accepts an incoming call, the connection manager SHOULD change the direction of any streams with pending local send to be sending, without altering whether those streams are receiving. This matches existing practice, and means that a client can answer incoming calls and get an unmuted microphone/activated webcam without having to take additional action to accept the stream directions. """ I hope this at least gets you in the right direction if you weren't there already.

I didn't realise you needed any more than this.
This page:
https://garage.maemo.org/plugins/wiki/index.php?com.nokia.csd.Call&id=1106&type=g
has a link to this file at the top:
http://www.bleb.org/software/maemo/telephony-maemo.c
which contains this code snippet:
static int answer_call(struct csd_call *call)
{
DBusMessage *msg;
msg = dbus_message_new_method_call(CSD_CALL_BUS_NAME,
call->object_path,
CSD_CALL_INSTANCE,
"Answer");
if (!msg) {
error("Unable to allocate new D-Bus message");
return -ENOMEM;
}
g_dbus_send_message(connection, msg);
return 0;
}
and you get the csd_call object by listening for the "Coming" signal as
you can see from the code snippet which is linked to in this page, and
then searching for calls with the "COMING" status:
>> http://wiki.maemo.org/Documentation/Maemo_5_Developer_Guide/DBus/DBus_in_Freemantle
Which I found out in about 15 minutes, reading the links I gave you.
Is this OK now?
Cheers,
Dave.
