3.9-current on i386 and amd64. (amd64 does not work yet).

You can build against the ossaudio(3) library but it really requires
native audio(4) support to work properly. That aside, (working from
memory and some incomplete notes) you need to do at least the
following (OpenBSD i386-current, linphone 1.3.5):

Disable linking against librt (-lrt) in mediastreamer2.
Adjust for the correct location of <soundcard.h> where needed.
Add <sys/types.h> to coreapi/enum.c
Provide a replacement or remove the dependency on <alloca.h> in
mediastreamer2/oss.c (I did the former).
Install a newer speex lib than provided by OpenBSD ports/packages.
Link against libossaudio (-lossaudio) where appropriate.
Make a link from /dev/audio to /dev/dsp
Tweak the configure/autoconf framework where needed.

Other than the newer speex lib, everything you need is provided
in the base system or is available in ports/packages.

Quick fix:
env CFLAGS="-I/usr/local/include -L/usr/local/lib" ./configure

Yuck. No thanks, that's not an option for me (or I suspect most other
OpenBSD users/developers).

I'm working on native audio(4) support, everything else works fine.
I have registered with several servers/proxies (asterisk, siproxd and
two external (commercial) SIP service providers) with the linphone gui.
I can make and receive calls fine, but the audio is not useable, as the
oss emulation library isn't up to the job.

I only have a few scribbled notes with me and won't be able to look at
this again for a couple of weeks. When I'm home again I'll start sending
patches to Simon or the list for review (whichever is more appropriate).
In the mean time, this should get you a bit further, at least.
