Are IP phones leased or purchased?
From PhonePower Knowledge Base
IP phones are either leased or sold. If you choose one of the business plans, you can lease-to-own a Linksys SPA-303G for $4.95 per month each or purchase one outright for $118.80. You can also lease a Linksys SPA-504G IP phone for $7.95 a month or purchase one for $190.80 each.
You may also buy an IP phone from somewhere else and use it with Phone Power. Check with our list of approved BYOD Hardware on the website to see if the IP phone you want to use is supported.
