Feature Description
PCF supports the full Diameter stack along with the standard Diameter interfaces like Rx. With this support, you can configure PCF to handle VoLTE calls for 4G and VoNR for 5G. In 4G scenarios, PCF serves as a proxy and performs the session binding lookups to re-route the 4G calls to the PCRF instances for processing. PCF supports the PCRF GR active/active mode for routing messages to the secondary PCRF site when the primary site is unavailable.
