Do you have internet connection? Is it affected as well? The TV installers would usually put in a Pot splitter in your home connection set-up to prevent phone service to affect TV and or internet connections. If no set up changes were made (like home alarm installation), you'll need to phone in Optik TV support at (your area code)3106988 or chat with them at www.telus.com/chat to arrange a service call to check on this.
