Are corded phones secure from interference?

A wired landline phone has a direct physical link to the network, which helps reduce the chance of wireless interference compared with cordless handsets or mobiles. This is one reason many clinics, professional services and customer-facing teams keep at least one corded handset on the desk. No system can promise complete protection from unauthorised access, but a simple corded landline telephone with no radio link is harder to intercept than a signal travelling over the air.
