You can now renew the Manufacture Installed Certificate (MIC) by a Secure Unique Device Identifier (SUDI) renewal service. This is an easy way to provide encryption and to help secure the phone. The MIC certificate involves some features that are related to SSL/TLS protocol. If the MIC certificate expires, these features don't work until you renew the certificate.

When this feature is enabled, the phone automatically renews the MIC certificate. Therefore, there's no additional action required by the user or admin.

To enable this feature, use the parameters under the MIC Cert Settings section from Voice > Provisioning.

This release supports new technology standard Secure Telephony Identity Revisited (STIR) and Signature-based Handling of Asserted information using toKENs (SHAKEN). STIR/SHAKEN has been mandated by Federal Communications Commission (FCC). These standards define procedures to authenticate and verify caller identification for calls carried over the IP network. The STIR-SHAKEN framework is developed to provide the end user with a great degree of identification and control over the type of calls they receive. These sets of standards are intended to provide a basis for verifying calls, classifying calls, and facilitating the ability to trust caller identity end to end. Illegitimate callers can easily be identified.

When STIR/SHAKEN support is implemented on the server, the phone displays an extra icon next to the caller ID based on the caller's STIR/SHAKEN verification result. Based on the verification result, the phone displays three types of icons.
