Michael I am speaking about compatability of current fs master and sip
client,  not old freeswith.
As example - about two months ago I tested linphone android build with
FreeSwith.  video artefacts is exits.
Linphone is updated frequently,  other sip clients may be not.

This doesn’t make any sense.  The newer vpx should work better, but I’ve
seen no bugs at all raised about them not being compatible.  If that is the
case, what we had previously in 1.5 (an unreleased development build)
should not be used anymore.

About proxy media. This may be necessary when used video calls using vpx
codec.

Vpx 1.6 used in FreeSwith is not compatible with vpx 1.5
Vpx 1.5 may be used in current sip clients

if zrtp passthrough is not working, please open a lira on this issue.  It
should be corrected.

suggestions? Originally, I thought proxy media would do the trick - pass
media packets without any attempt at interpretation but I noticed RTCP
wasn't being  activated (I think it was back in the 1.2.x days, I have an
ancient 1.2.5 that does activate RTCP). Any suggestions?
