Departments are asked to use their discretion to data-sanitize phones that carry a significant risk of disclosing sensitive institutional or personal data.

- Data-sanitize a Cisco VoIP phone by performing a factory reset. This requires plugging the phone into a powered Ethernet jack and then following a series of key strokes as described in the following link:
