I don't use the OBiTALK Web Portal. I log into the OBi directly at the IP address returned by dialing ***1. From there, it should be very obvious. If you decide to make changes directly to the OBi, it's necessary to set:
System Management -> Auto Provisioning -> Auto Provisioning -> Method : Disabled
Thanks very much. I should have looked there too. Is there some documentation somewhere that defines all this stuff for the newbie? I changed the auto provisioning method as directed, but I have no idea what it really means. Inquiring minds want to know... :-)
