Mitel Phones with HP Switches, NO VLANS and a 3rd Party VoIP Provider

I have a new position and my first priority is to figure out how everything is configured. I'm working on the phones right now.

I've discovered the following:
Mitel IP Phones from Broadview (model 5224 for the most part)
Dedicated T-1 for the phones (Fairly certain of this)
There are NO VLANs configured on any of the switches
The phones show up in the HP switches under the LLDP Remote Devices with 10.160.x.x addresses (not used on any of my LANS)
1 port on 1 switch is plugged into the router provided by Broadcom
The T-1 mentioned earlier has public addresses assigned to at least one interface, however there are TWO T-1 lines going into it. (I doubt they are bonded so we may actually have one internet and one private circuit in this router, as I don't have console access I have no idea how it's configured other than what it's plugged into)

I'm assuming that the phones are getting their information from an LLDP broadcast, picking up their private IP and going on their merry way.

First question- Here's what I don't get. Is LLDP used in place of a VLAN? I don't seem to have any access to the IP addresses the phones are getting and the PCs plugged into the phones operate as expected on my own LAN addresses.

I've always done this with a separate VLAN for the VoIP traffic but this seems to work with no need to mess with the switches and ports.

Second question and most imporant- I would like to extend the phones to be able to work on other routed subnets on my campus. Right now we have POTS lines in the remote areas. I have to assume this has to do with LLDP not crossing routers or VPNs? Correct? How can I get around this?

One area on campus uses an MPLS line and two routers. Data moves fine, phones obviously don't work. I'd love to be able to route this to some of our VPN'd locations too.

Any ideas or directions?

Thanks!
