Enable digest authentication

AI-generated summary

Genesys Cloud enables digest authentication configuration for both external and phone SIP trunks to secure inbound and outbound SIP requests. External trunks support digest authentication for both directions, while phone trunks support inbound digest authentication only. To configure outbound digest authentication on external trunks, administrators must access the Telephony > Trunks menu, select the desired external trunk, enable the outbound digest authentication checkbox, specify the authentication realm, and enter credentials (username and password). For phone trunks, inbound digest authentication is configured through the same menu path by selecting the phone trunk, enabling inbound digest authentication, choosing the SIP method to be challenged, entering the realm, and providing credentials. Both configurations allow administrators to mask or display passwords in plain text. The feature requires Telephony > Plugin > All permissions to access these settings.
