Mediant 3000

Source IP Group (to which the call belongs)

Source and destination Request-URI host name prefix

Source Trunk Group (from where the call is received)

Source (calling) and destination (called) telephone number prefix and suffix

Source and destination Request-URI host name prefix
The destination of the call can be one or more of the following:

IP address in dotted-decimal notation.

Fully Qualified Domain Name (FQDN).

E.164 Telephone Number Mapping (ENUM service).

Lightweight Directory Access Protocol (LDAP). For a description, see 'Routing Based
on LDAP Active Directory Queries' on page
205 .

IP Group, where the call is routed to the IP address configured for the Proxy Set or
SRD associated with the IP Group (configured in 'Configuring IP Groups' on page
230 ). If the device is configured with multiple SRDs, you can also indicate (in the
table's 'Dest. SRD' field) the destination SRD for routing to one of the following
destination types - IP address, FQDN, ENUM, or LDAP. If the SRD is not specified,
then the default SRD (0) is used. In scenarios where routing is to an IP Group, the
destination SRD is obtained from the SRD associated with the IP Group (in the IP
Group table). The specified destination SRD determines the:
•
Destination SIP interface (SIP port and control IP interface) - important when
using multiple SIP control VLANs
•
Media Realm (port and IP interface for media / RTP voice)
•
Other SRD-related interfaces and features on which the call is routed
Since each call must have a destination IP Group (even in cases where the
destination type is not to an IP Group), in cases when the IP Group is not specified,
the SRD's default IP Group is used, which is the first configured IP Group that belongs
to the SRD.
