In another post, you mention that you wire your ATA directly into your home's phone jacks.
Keep in mind that if you're connecting your ATA directly to the phone jacks in your house, unless you disconnect the telephone company's line at the demarc, power running from the telephone company's line into your phone jacks can fry your ATA:

If you want a recommendation, Obihai makes the most powerful ATAs intended for residential use. The real successors to the PAP2 series are Obihai ATAs (OBi2xx series sold at Newegg.ca would be the most powerful choice in terms of features, with the understanding that Obihai has a bad online reputation for its support policies) and not newer SPA series ATAs. The engineers that developed the PAP2 series eventually left and designed Obihai ATAs. Visit

OBi202, which has two phone ports, doesn't seem to be shipped and sold by Newegg Canada at the time of this post while the OBi200, which only has one phone port, is available to be shipped and sold by Newegg. If you're interested in the OBi202, google Acrovoice and contact them to see if they can order and ship an OBi202 to you. Newegg Canada and Acrovoice are the only authorized Obihai retailers in Canada. You might find this thread useful for alarm systems:
http://forum.fongo.com/viewtopic.php?f=8&t=19236. I don't, typically, try to offer technical assistance for alarm systems. An OBi202 would make more sense than an OBi200 if you plan to use a single FPL account for both your home phone and alarm system. I offer no guarantees that any ATA, even an Obihai, will work with your alarm system.

Avoid fake PAP2s and other fake, discontinued Linksys/Cisco ATAs from China sold on eBay and Kijiji:
