CHAPTER25 Routing
Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
â– If you select an IP Group, you do not need to configure a
destination IP address. However, if both parameters are
configured in the table, the INVITE message is sent only
to the IP Group.
â– If the destination is a User-type IP Group, the device
searches for a match of the Request-URI in the received
INVITE to an AOR registration record in the device's
database. The INVITE is then sent to the IP address of
the registered contact.
â– If the AlwaysUseRouteTable parameter is set to 1 (see
Configuring IP Groups), the Request-URI host name in
the INVITE message is set to the value configured for the
'Destination IP Address' parameter (in this table);
otherwise, if no IP address is defined, it is set to the value
of the 'SIP Group Name' parameter (configured in the IP
Groups table).
â– The parameter is used as the 'Serving IP Group' in the
Accounts table for acquiring authentication
username/password for this call (see Configuring
Registration Accounts).
â– To configure Proxy Sets, see Configuring Proxy Sets.
'SIP Interface'
dest-sip-interface-
name
[PREFIX_
DestSIPInterfaceName]
Assigns a SIP Interface to the routing rule. The call is sent to
its' destination through this SIP interface.
To configure SIP Interfaces, see Configuring SIP Interfaces.
Note: If a SIP Interface is not assigned, the device uses the
SIP Interface associated with the default SRD (Index 0). If,
for whatever reason, you have deleted the default SRD and
there are no SRDs, the call is rejected.
'Destination IP Address'
dst-ip-address
[PREFIX_DestAddress]
Defines the IP address (in dotted-decimal notation or FQDN)
to where the call is sent. If an FQDN is used (e.g.,
domain.com), DNS resolution is done according to the
DNSQueryType parameter.
The IP address can include the following wildcards:
â– "x": represents single digits. For example, 10.8.8.xx
denotes all addresses between 10.8.8.10 and 10.8.8.99.
â– "*": represents any number between 0 and 255. For
example, 10.8.8.* denotes all addresses between
10.8.8.0 and 10.8.8.255.
For ENUM-based routing, enter the string "ENUM". The
device sends an ENUM query containing the destination
phone number to an external DNS server (configured in the IP
Interfaces table. The ENUM reply includes a SIP URI which
is used as the Request-URI in the subsequent outgoing
INVITE and for routing (if a proxy is not used). To configure
the type of ENUM service (e.g., e164.arpa), see the
EnumService parameter.
