Bug#1036082: linphone: Unable to enable H.264 video codec required for Zoom SIP connections

[Petter Reinholdtsen]

Package: linphone
Version: 4.2.5-3
Severity: important

Dear Maintainer,

Any calls to the SIP endpoint for the Zoom video chat service fail.  I
discovered  <URL: https://github.com/bemoody/linphone-deb > with a
recipe for how to get it working, but the "Enable H.264 video compression"
step fail.  When I try to enable the video codec, a popup message ask if
it is OK to download the codec, but even if I accept the download and
press the strange empty 'confirm' popup afterwards, the H.264 video
codec option stay disabled.

And without H.264 video codec available, the call is rejected.  I
verified this using Jami, which I normally can use to connect to the
SIP endpoint of Zoom, but it will fail when I disable H.264.
