You log into the OBi itself using the IP address returned by dialing ***1. The default username/password is admin/admin, but the password may have been changed if you added the OBi to the OBiTALK Web Portal Dashboard (the current password should be displayed there).
If you configure the OBi directly instead of using the OBiTALK Web Portal, you must also set:
System Management -> Auto Provisioning -> ITSP Provisioning -> Method : Disabled
System Management -> Auto Provisioning -> OBiTALK Provisioning -> Method : Disabled
or the OBiTALK Web Portal will overwrite any changes you make directly.
