If you've been configuring the OBi yourself and just added it yesterday, the act of adding the OBi to the OBiTALK Web Portal Dashboard wiped out everything in the OBi, even if you had Auto Provisioning disabled.
If you have a backup of your configuration, you can remove the OBi from the OBiTALK Web Portal and restore your backup. Otherwise, you start all over again, either manually as you were doing or using the OBiTALK Web Portal.
