<div>We are maxed out on our legacy PBX, and the question is the process of migrating to a new * system from the legacy. We current have 36 FXO lines coming into our site, and the usage on these lines indicates we can spare a few of them to launch the * server, and then move additional lines over as the * server/network/cable plant is built out and traffic moves to *. Eventually, we will want to merge all oustide traffic to SIP WAN circuit terminated on *.</div>
<div> </div>
<div>The question is what * telephony interface hardware to use for the migration. At the beginning we need a couple of FXO ports, and at the end we will want to have some kind digital trunking.</div>
<div> </div>
<div>Any recommendation for hardware to use throughout this migration process?</div>

<div>Thanks a bunch!</div>
