Using a landline with original SS base station
Can I use a landline with the original SS base station to connect to the dispatch center?
If I plug in the landline to the base station, how will I know if the landline connection is working (vs. the cellular connection)?
The cell signal where I live (rural west Michigan) can be somewhat flaky. I would like to use the landline as a "backup" connection in case the cellular connection fails. Has anyone done this?
And, by the way, the landline I have is actually provided by a fiberoptic internet modem. The telephones connected to it work fine.
