21 May 2016, ivrSVR 1.2.0 just released. This version
1. Supports SelectiveListeningHold() and SelectiveListeningRetrieve() API
2. Supports permanent connection between ivrSVR and uuiSVR to make the add, update and delete of user data more efficient.
3. Fixed a bug that ivrSVR will not startup successfully before AES startup.
