From a user standpoint, it is not terrible, especially considering what it is doing. It is definitely not as real time as a standard phonecall, but if you are not in the same room, you hardly notice it.
Perhaps we should audit: http://trac.pjsip.org/repos/browser/pjproject/trunk/pjmedia/... and http://svn.pjsip.org/repos/pjproject/trunk/third_party/srtp/... ?
The CSipSimple solved the latency issue by utilizing the native PJSIP C library for all heavy lifting: http://www.pjsip.org/ http://code.google.com/p/csipsimple/
RedPhone had some nice optimizations like tying into your existing public phone number (perhaps a privacy issue depending upon your view), and using SMS or Google's Push service to ensure your device is not sleeping…
