Providing phone servers over the WAN with Cisco Call Manager
I currently have CUCM 9.1.2 and Unity Connection 9.1.2 installed in a retirement community. I currently provide phones, VM, and autoattendent to the business side of the organization. We are going to start providing phone service to the residents who live in the retirement community as well. Now most residents who live there have a standard 2 wire phone, so my first question is, I will need to install a Cisco ATA for each person who has an analog phone for this to work right?
My Second question is regarding providing phone access over the WAN. This retire community has cottages that are not connected to the wired network, and won't be. I've been asked if its possible to provide them phone access over their internet connection off the call manager (each cottage has their own internet connection provided to them via the provider of their choice whether it be verizon, comcast, etc. Site to Site VPN isn't an option here, so it would have to go over the WAN. How would i accomplish this? The people who live in the cottages will also have a regular RJ11 phone, not a cisco VOIP phone. Any ideas would be greatly appreciated.

Thanks.
Yes, the WAN users is what I'm not sure about. I'm having problems coming up with a solution for them.

Why not a site to site VPN? I use them for all our remote workers, although it does mean they have a Cisco small business router or ASA 5505 installed to provide it.
An issue you may have is if they want to talk to another cottage, however, as they will have to be on different networks to VPN and there is a limitation on the small business devices.
I believe it is possible to provide phone services without the VPN, by publishing the CM to the internet and using certificates to the phone handsets, but they would need to be Cisco for that to work.

Site to Site VPN is not an option. There are way to many houses throughout the community. If this was a branch office, i would absolutely do a site to site VPN, but these are like 100 houses. What I really want to do is provide them phone service over their own WAN connection. For example, if I configured a static NAT for the CUCM to make it public facing, could i register a phone over the WAN? I feel like this would be something common, but I don't see anything really about this when researching.

Thanks. That was my feelings as well. I really don't want to the make the CUCM public. Thanks for your insight.
I'm sure there's a way to accomplish the WAN users, but I'm not up to speed on the latest methods.
