“Can the main console CM18445 connect to my existing 4-line Comcast system as an add-on? The existing phones are AT&T 1070 wired phones. Not wireless. Does that matter? OR does the entire phone system need to start with CM18445?”

• Hi - The VTech CM18445 is not compatible with another 4 line telephone system. The only compatible devices with the Console are the expansion units model CM18045 and CM18245. Thank you, -VTech Support
