Self-signed certificates don’t provide the guarantees of a certificate signed by a certificate authority but can be useful if the person signing it is trusted. You can create a self-signed certificate using the Certificate Assistant in Keychain Access. To ensure the highest sound quality, we recommend using a Skype for Business compatible device. Create self-signed certificates in Keychain Access on Mac. Depending on your personal workspace, it may be possible to make calls using your computer’s internal microphone and internal/external speakers in an enclosed office space. For information about recommended Skype for Business compatible devices available via KUPPS, visit Skype for Business Recommended Devices.Īlternately, while Skype for Business compatible headsets or desk phones are recommended for voice calls, only a microphone and speaker, while not optimal, are required to place or receive voice calls via Skype for Business. All optional and future equipment/device purchases are the responsibility of individual units. Contact your unit’s procurement staff or technology support staff for applicable policies and information. Units have the option of purchasing Skype for Business compatible desk-style phones and personal USB speakerphones at the discretion of unit leadership. University leadership has determined that headsets will replace desk phones for most faculty and staff.
