Bug#602772: ekiga, remote can unmute audio and unsuspend video

[David Fries]

Package: ekiga
Version: 3.2.7-2
Severity: normal


Start an ekiga video conference, tell ekiga to suspend audio and video
output (other side gets silence and no more video as expected), but
when the remote suspends or resumes their video, the local side starts
to send audio and video without any indication to the user.  This can
allow the remote side to eavsdrop thinks they are muted and not
sending video.

In my case the remote client is the N900 Telepathy-SofiaSIP/0.6.2
client.

>From ekiga's point of view when only the video was suspended, received

Is ekiga seeing the "a=recvonly" and doing what it was instructed to
do, that is send video?
