A:Answer No. This model connects to your router or in-wall Ethernet jack (etc., etc.) using the provided ethernet cable.
The Tel line out (on the Ooma) would simply plug into your compatible landline phone of choice, OR via the pre-existing telephone wiring/jacks in your home (that have been decommissioned by the TelCo, including the TelCo access point from the utility pole).**
**Note: That’s assuming it isn’t a birdsnest of splices in the walls/attic, and assuring it will not exceed the Ooma’s limits/specs.
Hope that makes sense and helps.
