Ooma Office questions

I run a small office with 4 employees. Our set-up is 4 individual offices with desktop phones, + 1 reception desktop phone, +1 breakroom phone, +1 conference room phone.

All in all we have 6 phones + a 1 conference room phone.

Currently we use an old Comdial system with a physical terminal in our office. Comcast provides our internet and phone lines. Their costs are ridiculous so we are looking for a new system. Most of the systems out there seem to cater to larger businesses than ours. We're a small mom & pop property management company that doesn't solicit sales and only uses the phones for basic in and out communications to tenants and the vendors we use to complete repairs. Most of the time only 1-2 of us are in the office & a few of the newer providers seem to charge "per unit or phone" which is not cost effective for us.

For those of you with experience using Ooma Office, do you think it would be a good fit for our size & needs?

How is the quality of the service?

Do they charge extra for reception, breakroom, and conference room phones? I know the charges are "user" based, but I'm unsure if having these location specific extra phones would require us to add a "user" for them to work.

Any and all replies are appreciates, and thanks in advance!
