Your wife must really like calls from air duct cleaning or other telemarketers I cancelled my landline because they're the only ones that called me and usually at dinner time.My wife will not let me cancel the home phone so I canceled the $60/ month Rogers and switched to $5/month ooma with absolutely zero change in service reliability.
A cellphone makes a landline redundant IMO and I can screen out any calls that aren't on my contact list.
