Configuring SRD Table

The SRD Settings page allows you to configure up to 32 signaling routing domains (SRD).
An SRD is configured with a unique name and assigned a Media Realm.
An SRD is a set of definitions together creating multiple, virtual multi-service IP gateways:

Multiple and different SIP signaling interfaces (SRD associated with a SIP Interface)
and RTP media (associated with a Media Realm) for multiple Layer-3 networks.

Can operate with multiple gateway customers that may reside either in the same or in
different Layer-3 networks as the device. This allows separation of signaling traffic
between different customers. In such a scenario, the device is configured with multiple
SRD's.
Typically, one SRD is defined for each group of SIP UAs (e.g. proxies, IP phones,
application servers, gateways, and softswitches) that communicate with each other. This
provides these entities with VoIP services that reside on the same Layer-3 network (must
be able to communicate without traversing NAT devices and must not have overlapping IP
addresses).
destination (IP Group or destination address) indicates the SRD to which it belongs.
Once configured, you can use the SRD as follows:

Associate it with a SIP Interface (see 'Configuring SIP Interface Table' on page 202)

Associate it with an IP Group (see 'Configuring IP Groups' on page 204)

Associate it with a Proxy Set (see 'Configuring Proxy Sets Table' on page 209)

Define it as a Classification rule for the incoming SIP request (see Configuring
Classification Rules)

Use it as a destination IP-to-IP routing rule (see 'Configuring Outbound IP Routing
Table' on page 309)
The SRD Settings page also displays the IP Groups, Proxy Sets, and SIP Interfaces
associated with a selected SRD index.
Notes:
•
On the SRD Settings page, you can also configure a SIP Interface in the SIP
Interface table, instead of navigating to the SIP Interface Table page as described
in 'Configuring SIP Interface Table' on page 202.
•
The SRD table can also be configured using the table ini file parameter, SRD.

To configure SRDs:
1. Open the SRD Settings page (Configuration tab > VoIP menu > Control Network
submenu > SRD Table).
2. From the 'SRD Index' drop-down list, select an index for the SRD, and then configure
it according to the table below.
Version 6.6
Routing from one SRD to another is possible, whereby each routing
