1. What "does not work"? You cannot call to the GV number or you cannot reach the AA or you cannot get the AA to do what you want?
2. To configure GV you MUST use the OBiTALK portal. Having done so, it is easier to continue using that for all your configuration changes. Unless you specifically first use the 202's own GUI to disable OBiTALK provisioning, any changes you make via that GUI will be quickly overwritten with the configuration held on the OBiTALK server.
