User's Manual 17. Control Network
Parameter Description
[MediaRealmExtension_PortRangeEnd]
ports for the Media Realm Extension.
Note: It is unnecessary to configure the parameter. The
device automatically populates the parameter with a
value, calculated by the summation of the 'Number of
Media Session Legs' parameter (multiplied by the port
chunk size) and the 'Port Range Start' parameter. After
you have added the Media Realm Extension row to the
table, the parameter is displayed with the calculated
value.
Number Of Media Session Legs
[MediaRealmExtension_MediaSessionLeg]
Defines the number of media sessions for the port
range. For example, 100 ports correspond to 10 media
sessions, since ports are allocated in chunks of 10.
By default, no value is defined.
Note: The parameter is mandatory.
17.2 Configuring SRDs
The SRDs table lets you configure up to 41 signaling routing domains (SRD) for Gateway
and SBC calls. The SRD is a logical representation of an entire SIP-based VoIP network
(Layer 5) consisting of groups of SIP users and servers. The SRD is associated with all the
configuration entities (e.g., SIP Interfaces and IP Groups) required for routing calls within
the network. Typically, only a single SRD is required (recommended) for most
deployments. Multiple SRDs are only required for multi-tenant deployments, where the
physical device is "split" into multiple logical devices. For more information on multi-tenant
architecture, see ''Multiple SRDs for Multi-tenant Deployments'' on page 323.
As the device is shipped with a default SRD ("DefaultSRD" at Index 0), if your deployment
requires only one SRD, you can use the default SRD instead of creating a new one. When
only one SRD is employed and you create other related configuration entities (e.g., SIP
Interfaces), the default SRD is automatically assigned to the new configuration entity.
Therefore, when employing a single-SRD configuration topology, there is no need to
handle SRD configuration (i.e., transparent).
SRDs are associated with the following configuration entities:

SIP Interface (mandatory) - see ''Configuring SIP Interfaces'' on page 326

IP Group (mandatory) - see ''Configuring IP Groups'' on page 333

Proxy Set (mandatory) - see ''Configuring Proxy Sets'' on page 346

(SBC application only) Admission Control rule - see Configuring Admission Control
Table on page
643

(SBC application only) Classification rule - see Configuring Classification Rules on
page
647
As mentioned previously, if you use only a single SRD, the device automatically assigns it
to the above-listed configuration entities.
As each SIP Interface defines a different Layer-3 network (see ''Configuring SIP Interfaces''
on page 326 for more information) on which to route or receive calls and as you can assign
multiple SIP Interfaces to the same SRD, for most deployment scenarios (even for multiple
Layer-3 network environments), you only need to employ a single SRD to represent your
VoIP network (Layer 5). For example, if your VoIP deployment consists of an Enterprise IP
PBX (LAN), a SIP Trunk (WAN), and far-end users (WAN), you would only need a single
SRD. The single SRD would be assigned to three different SIP Interfaces, where each SIP
