SIP User's Manual 3. Web-Based Management
3.4.5.2 Configuring Media Realms
The 'SIP Media Realm Table' page allows you to define a pool of up to 16 media interfaces,
termed Media Realms. This table allows you to divide a Media-type interface (defined in the
'Multiple Interface' table - refer to ''Configuring the Multiple Interface Table'' on page 58) into
several realms, where each realm is specified by a UDP port range. Once created, the
Media Realm can be assigned to other elements such as an IP Group (in the 'IP Group'
table) or an SRD (in the 'SRD' table).
Notes:
• Up to 16 Media Realms can be configured in this table. However, only up
to 8 Media Realms can be used by the device (as a maximum of 8 IP
Groups can be configured).
• You can also configure the Media Realm table using the ini file table
parameter CpMediaRealm.
• If different Media Realms are assigned to an IP Group and to an SRD,
the IP Group’s Media Realm takes precedence.
• For this parameter to take effect, a device reset is required.
¾ To define a Media Realm:
1. Open the 'SIP Media Realm Table' page (Configuration tab > Protocol
Configuration menu > Media Realm Configuration page item).
