No, not directly. Shaw provides a device that interfaces with your existing home wiring infrastructure so it works like the POTS service you'd get from Telus. (which is a bit more of an advantage as you can now use any cheap off the shelf phone that you can buy anywhere).
The SPA502G will work with a Cisco PBX, or a VoIP phone service that uses SIP (like FreePhoneLine, VoIP.ms) but not for the residential phone service that Shaw provides.
