Table 27-2: SAS IP-to-IP Routing Table Parameters
Parameter Description
Matching Characteristics
Source Username Prefix
[IP2IPRouting_SrcUsernamePr
efix]
Defines the prefix of the user part of the incoming SIP dialog's
source URI (usually the From URI). You can use special
notations for denoting the prefix. For example, to denote any
prefix, use the asterisk (*) symbol; to denote calls without a user
part in the URI, use the $ sign. For available notations, see
'Dialing Plan Notation for Routing and Manipulation' on page 405.
The default is * (i.e., any prefix).
Source Host
[IP2IPRouting_SrcHost]
Defines the host part of the incoming SIP dialog's source URI
(usually the From URI). If this rule is not required, leave the field
empty. To denote any host name, use the asterisk (*) symbol
(default).
Destination Username Prefix
[IP2IPRouting_DestUsernameP
refix]
Defines the prefix of the incoming SIP dialog's destination URI
(usually the Request URI) user part. You can use special
notations for denoting the prefix. For example, to denote any
prefix, use the asterisk (*) symbol; to denote calls without a user
part in the URI, use the $ sign. For available notations, see
'Dialing Plan Notation for Routing and Manipulation' on page 405.
The default is * (i.e., any prefix).
Destination Host
[IP2IPRouting_DestHost]
Defines the host part of the incoming SIP dialog’s destination URI
(usually the Request-URI). If this rule is not required, leave the
field empty. The asterisk (*) symbol (default) can be used to
denote any destination host.
Message Condition
[IP2IPRouting_MessageConditi
on]
Selects a Message Condition rule. To configure Message
Condition rules, see Configuring Condition Rules.
ReRoute IP Group ID
[IP2IPRouting_ReRouteIPGrou
pID]
Defines the IP Group that initiated (sent) the SIP redirect
response (e.g., 3xx) or REFER message. This field is typically
used for re-routing requests (e.g., INVITEs) when interworking is
required for SIP 3xx redirect responses or REFER messages (for
more information, see Interworking SIP 3xx Redirect Responses
and Interworking SIP REFER Messages, respectively). This
parameter functions together with the 'Call Trigger' field (see
below).
The default is -1 (i.e., not configured).
Call Trigger
[IP2IPRouting_Trigger]
Defines the reason (i.e, trigger) for re-routing the SIP request:
ï‚§ [0] Any = (Default) This routing rule is used for all scenarios
(re-routes and non-re-routes).
ï‚§ [1] 3xx = Re-
