4G LTE wifi Orbi Router / use with corded phone

[DaveNet02]

Trying to replace an AT&T Home Base with the LBR20 to take advantage of support of additional LTE4G bands.  The Home Base has a phone jack out, which we use as an actual corded home phone system (same number as the SIM card is assigned by AT&T).  The LBR20 does NOT have a phone jack.  HOW can I hook up a phone using the LBR20?

Note to Netgear:  Adding a phone jack to this system would be a winner.

You'd need to subscribe to a VOIP service like Ooma. 

the LBR20 doesn't have a voice service built in.
