Version 7.2 347 Mediant 800B Gateway & E-SBC
User's Manual 17. Control Network
Parameter Description
IPv6 Interface Name
[MediaRealmExtension_IPv6IF]
Assigns an IPv6 network interface (configured in the IP
Interfaces table) to the Media Realm Extension.
By default, no value is defined.
Note:
The parameter is mandatory.
You must configure the Media Realm Extension with
an IP network interface that has the same IP
version(s) as the Media Realm to which the Media
Realm Extension is associated. If the associated
Media Realm is assigned both an IPv4 and IPv6
network interface, you also need to assign the Media
Realm Extension with both an IPv4 and IPv6 network
interface. For example, if the associated Media
Realm is assigned only an IPv6 network interface,
you also need to assign the Media Realm Extension
with an IPv6 network interface.
Port Range Start
[MediaRealmExtension_PortRangeStart]
Defines the first (lower) port in the range of media UDP
ports for the Media Realm Extension.
By default, no value is defined.
Notes:
You must either configure all your Med
port ranges or all without; not some with and some
without.
The available UDP port range is according to the
BaseUDPport parameter. For more information, see
'Configuring RTP Base UDP Port' on page 210.
Port Range End
[MediaRealmExtension_PortRangeEnd]
Defines the last (upper) port in the range of media UDP
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
