[Telepathy] Telepathy Streamtubes

[Olli Salli]

Hi,

unfortunately, that's not very well supported by current tp-qt API.
There is a wrapper API for DBusTube channels awaiting to be merged at
https://bugs.freedesktop.org/show_bug.cgi?id=28366 but even that is
well below the convenience level offered by StreamTubeServer/Client
for Stream tubes. So I suggest you use stream tubes with tp-qt >=
0.8.0, or use tp-glib which has better support for dbus tubes at the
moment.

Is there any way I can get the sender email id information from the incoming stream tube channel at receiver side before the connection is accepted by receiver.
