Configuring Media Realms

The Media Realm table lets you configure a pool of up to 64 SIP media interfaces, termed
Media Realms. Media Realms allow you to divide a Media-type interface (configured in the
Interface table) into several realms, where each realm is specified by a UDP port range.
Media Realms also define the maximum number of permitted media sessions. Media
Realms can later be assigned to IP Groups (see ''Configuring IP Groups'' on page 263) and
SRDs (see ''Configuring SRDs'' on page 258).
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 242.

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 246.
You can also configure remote destination subnets per Media Realm and assign each
subnet a Quality of Experience Profile and Bandwidth Profile. For configuring Remote
Media Subnets, see ''Configuring Remote Media Subnets'' on page 256.
Notes:
•
If an IP Group is associated with an SRD and different Media Realms are
assigned to the IP Group and SRD, the IP Group's Media Realm takes
precedence.
•
If you modify a Media Realm currently being used by a call, the device does not
perform Quality of Experience for the call. If you delete the Media Realm during
the call, the device maintains the call until the call parties end the call.
The following procedure describes how to configure Media Realms in the Web interface.
You can also configure Media Realms using the table ini file parameter, CpMediaRealm or
CLI command, configure voip/voip-network realm.
