Here is a modified PKGBUILD that pulls the svn instead to get 'pjsystest' and the corresponding wav files. You have to copy them from /usr/share/pjproject to a writable folder and start 'pjsystest'.
I actually needed that to test latency and list detected audio devices and audio backends.
Latency isn't that good here though (245ms roundtrip) on Audigy2 with Portaudio. I've tried ALSA and JACK as well but i don't get them properly working (JACK partially/scrambled, ALSA doesn't initialize properly). They can be optionally enabled in the PKGBUILD marked as experimental.
JACK would be the low-latency killer feature for SIP apps but there is none supporting it. JACK2-dbus doesn't work with portaudio anymore either.

PSA: I've started hosting this and also many other packages I maintain in the AUR as prebuilt packages in my repository for those that want to install them using
pacmanwithout messing around with building from the AUR.
