Default Media Realm 
is-default 
[CpMediaRealm_IsDefault] 
Defines the Media Realm as the default Media Realm. The 
default Media Realm is used for SIP Interfaces and IP Groups 
for which you have not assigned a Media Realm. 
  [0] No (default) 
  [1] Yes 
Note: 
  You can configure the parameter to Yes for only one 
Realm; all the other Media Realms must be configured to 
No. 
  If you do not configure the parameter (i.e., the parameter is 
No for all Media Realms), the device uses the first Media 
Realm in the table as the default. 
  If the table is not configured, the default Media Realm 
includes all configured media interfaces.  
Quality of Experience 
QoE Profile 
qoe-profile 
[CpMediaRealm_QoeProfile] 
Assigns a QoE Profile to the Media Realm.  
By default, no value is defined.  
To configure QoE Profiles, see ''Configuring Quality of 
Experience Profiles'' on page 315. 
BW Profile 
bw-profile 
[CpMediaRealm_BWProfile] 
Assigns a Bandwidth Profile to the Media Realm.  
By default, no value is defined.  
To configure Bandwidth Profiles, see ''Configuring Bandwidth 
Profiles'' on page 320. 
 
 
17.1.1  Configuring Remote Media Subnets 
Remote Media Subnets define destination subnets for media (RTP/SRTP) traffic on a 
specific Media Realm. Each Remote Media Subnet can be assigned different call quality 
(Quality of Experience Profile) and bandwidth utilization (Bandwidth Profile) profiles. These 
profiles are configured in ''Configuring Quality of Experience Profiles'' on page 315  and 
''Configuring Bandwidth Profiles''  on page 320, respectively. Thus, you can apply these 
profiles to remote media subnets instead of Media Realms or IP Groups. You can configure 
up to five Remote Media Subnets per Media Realm.
