I tested on Bookworm, and while it is different, I did not manage to
call the SIP endpoint of Zoom.

With the mediastreamer2-plugin-openh264 package installed, the H.264
option show up as enabled, and disabling and enabling it do not ask for
anything to be downloaded.  This is great.

The problem is that I try to connect it to my local Asterisk server,
which appear to not work.  I get a proxy account with the correct
settings, but linphone do not seem to reach the server.

Ignoring this, I try to enter the sip address of the Zoom room I want to
connect to, but entering it in the upper text field just pop up a 'add
contact' prompt that do not work (the 'sip address' field seem to be
write protected), and just pressing [enter] after cut-n-pasting the SIP
address just clear the field.

Cut-n-pasting the SIP address in the text field just below it also did
nothing.

In short, while H.264  might be working with Linphone in Bookworm, I
have no idea how to test it with my current setup.

Perhaps it only work when accepting the terms of the external service?

Would be interesting to know the answer to this question.

It behave a lot better.  I guess this issue can be seen as solved with
linphone version 5.1.65-4.  Still have not found a way to make Linphone
useful, but at least the download popup seem to be gone.

I am happy to debug some more, and am available on #debian-voip if
someone want direct contact.
