SIP with android

The google supplied SIP Demo (http://developer.android.com/resources/samples/SipDemo/index.html) fails with "can't register with asterisk" while it works fine on a Motorola Zoom. A hand coded SIP application that runs fine with the Motorola Zoom, the Galaxy Nexus, and the Motorola Android gets at least a 20% packet loss with android on the pandaboard (this could be either an ethernet connection problem - not likely, a sound driver problem - not likely, or a codec problem).

The real problem is how does a problem like this supposed to be reported/addressed?

Any help would be appreciated.
