• PBX Passthrough is enabled under SIP Access Control on the trunk, reached from Menu > Digital and Telephony > Telephony > Trunks > External Trunks. in context
• PBX passthrough requires the inbound or the outbound trunk to be a PBX trunk; passthrough between two carrier trunks is not supported. in context
• Genesys warns not to enable PBX passthrough on external trunks that connect to carriers because it exposes the organization to toll fraud. in context
• The PBX Passthrough setting on a BYOC PBX trunk lets the PBX pass calls intended for the PSTN through Genesys Cloud, routed by the site's number plan and outbound routes when the destination is not a Genesys Cloud user, station or IVR flow. in context
