SAS IP-to-IP Routing Table Parameters
Parameter Description
Matching Characteristics
Source Username Prefix
[IP2IPRouting_SrcUser
namePrefix]
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 501.
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_DestUse
rnamePrefix]
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 501.
The default is * (i.e., any prefix).
Destination Host
[IP2IPRouting_DestHos
t]
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_Messag
eCondition]
Selects a Message Condition rule. To configure Message Condition
rules, see Configuring Condition Rules.
ReRoute IP Group ID
[IP2IPRouting_ReRoute
IPGroupID]
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:
 [0] Any = (Default) This routing rule is used for all scenarios (re-
routes and non-re-routes).
 [1] 3xx = Re-routes the request if it was triggered as a result of a SIP
3xx response.
 [2] REFER = Re-routes the INVITE if it was triggered as a result of a
REFER request.
 [3] 3xx or REFER = Applies to options [1] and [2].
 [4] Initial only = This routing rule is used for regular requests that the
device forwards to the destination. This rule is not used for re-routing
of requests triggered by the receipt of REFER or 3xx.
