18 Core Entities
This section describes configuration of core SIP entities.
Configuring Media Realms
The Media Realms table lets you configure a pool of up to 1,024 SIP media interfaces, termed
Media Realms . Media Realms lets you divide a Media- type interface (configured in the IP
Interfaces table) into several media realms, where each realm is specified by a UDP port range.
Media Realms also define the maximum number of permitted media sessions.
Once configured, to apply Media Realms to specific calls, you need to assign them to any of the
following configuration entities:
■ IP Groups (see Configuring IP Groups )
■ SIP Interfaces (see Configuring SIP Interfaces )
You can also apply the device's Quality of Experience feature to Media Realms:
■ Quality of Experience Profile: Call quality monitoring based on thresholds for voice metrics
(e.g., MOS) can be applied per Media Realm. For example, if MOS is considered poor, calls on
this Media Realm can be rejected. To configure Quality of Experience Profiles, see
Configuring
Quality of Experience Profiles .
■ Bandwidth Profile: Bandwidth utilization thresholds can be applied per Media Realm. For
example, if bandwidth thresholds are crossed, the device can reject any new new calls on this
Media Realm. To configure Bandwidth Profiles, see
Configuring Bandwidth Profiles .
The Media Realms table provides the following "child" tables:
■ Remote Media Subnets: Defines remote destination subnets per Media Realm and assigns
each subnet a Quality of Experience Profile and Bandwidth Profile. For more information, see
Configuring Remote Media Subnets .
■ Media Realm Extensions: Defines port ranges for multiple Media-type interfaces per Media
Realm. For more information, see
Configuring Media Realm Extensions .
● The Media Realm assigned to an IP Group overrides any other Media Realm
assigned to any other configuration entity associated with the call.
● If you modify a Media Realm that is currently being used by a call, the device does
not perform Quality of Experience for the call.
● If you delete a Media Realm that is currently being used by a call, the device
maintains the call until the call parties end the call.
● The device provides a preconfigured Media Realm ("DefaultRealm") in the Media
Realms table, which you can modify or delete.
The following procedure describes how to configure Media Realms through the Web interface. You
can also configure it through ini file [CpMediaRealm] or CLI (
configure voip > realm
).
