You will need some type of VoIP -> Analog gateway. We have had great success with Multitech. There are different options to fulfill just about any request. You will need a gateway on both sides. FXO ports on the PBX side to accept your SLT analog dial tone and FXS ports on the remote side to feed analog dialtone to the devices. There are other manufacturers of this type of equipment but we have had good luck with Multitech so I push them.

We have actually done this at 2 different sites and, once set up, it has worked flawlessly. This was over wireless bridges.

At the dealership we are supporting fax machines and paging at the remote site with this solution. ~ Mike
