I would agree that adb is the better way, as copying these files in the phone ui had a near fatal impact for me.
On an off topic note, the overall SIP features and functionality of android's native phone is not anything to write home about (8khz), but it is convenient. It lacks support for something as simple g.722 and would make the world of difference for those of us that have other sip phones where16 kHz audio is the norm.
