Android SipManager关闭给出错误“无数据连接”

Question

Using the built-in Android SIP stack, I have a soft phone that successfully registers and makes calls. But when exiting the app I call the SipManager's close() method I see using "adb logcat" that it fails to unregister because it doesn't have a data connection. The phone I'm testing with is on WIFI and has uninterrupted access the whole time. Any ideas? Thank you in advance.

Code:

manager.close( me.getUriString() );

SipRegistrationListener calls method onRegistrationFailed() with errorCode -10 (DATA_CONNECTION_LOST) and errorMessage "no data connection". From "adb logcat":

D/CallManager( 3197): unregisterPhone(SIP:2345678@12.34.56.78 Handler (com.android.internal.telephony.sip.SipPhone) {4355db80})
D/MyPhone(10130): MyService.MyMethod() Got "onRegistrationFailed" with errorCode "-10" and errorMessage "no data connection".
