No. Anything that you can do with your phone line now will still be possible when the SPEEDe service is installed, since it does not affect calling services or normal voice/data communications.

For example, if you currently subscribe to any of Bell's SmartTouch services such as Call Waiting or Call Answer, use the fax or voice capabilities of your regular dial-up modem, or have an answering machine, they will continue to work the same as they always have.
