Configuring Media Realms

The Media Realm table lets you configure a pool of up to 64 SIP media interfaces, termed
Media Realms. Media Realms lets you divide a Media-type interface (configured in the
Interface 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'' on page 343)

SIP Interfaces (see ''Configuring SIP Interfaces'' on page 337)
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. For configuring Quality of
Experience Profiles, see ''Configuring Quality of Experience Profiles'' on page 309.

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. For configuring Bandwidth Profiles, see ''Configuring
Bandwidth Profiles'' on page 313.
The Media Realm table provides sub-tables ("child" tables) that let you configure the
following:

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'' on page 322.

Media Realm Extensions: Defines port ranges for multiple Media-type interfaces per
Media Realm. For more information, see ''Configuring Media Realm Extensions'' on
page 324.
Notes:
•
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 following procedure describes how to configure Media Realms through the Web
interface. You can also configure it through ini file (CpMediaRealm).

To configure a Media Realm:
1. Open the Media Realm table (Configuration tab > VoIP menu > VoIP Network >
Media Realm Table).
