I have an OBi100 with FreePhoneLine, and whenever there is a power outage, my device automatically registers again once the outage is over.
However, my parents also have an OBi100, but with voip.ms, and whenever they recover power after an outage, they have to reboot the OBi to get their line back, even though the lights on the device are all green.
Does this have anything to do with their service provider, or with their router? Is there anything I can do to make the device register back automatically?
