SIP User's Manual 876 Document #: LTRT-12804
Mediant 800 MSBG
Parameter Description
[SASEmergencyPrefix]
Defines a prefix that is added to the Request-URI user part of the
INVITE message that is sent by the device's SAS agent when in
Emergency mode to the default gateway or to any other
destination (using the 'IP2IP Routing' table). This parameter is
required to differentiate between normal SAS calls routed to the
default gateway and emergency SAS calls. Therefore, this allows
you to define different manipulation rules for normal and
emergency calls.
This valid value is a character string. The default is an empty
string "".

[SASRegistrationManipulation]
This ini file table parameter configures the SAS Registration
Manipulation table. This table is used by the SAS application to
manipulate the SIP Request-URI user part of incoming INVITE
messages and of incoming REGISTER request AoR (To header),
before saving it to the registered users database. The format of
this table parameter is as follows:
[SASRegistrationManipulation]
FORMAT SASRegistrationManipulation_Index =
SASRegistrationManipulation_RemoveFromRight,
SASRegistrationManipulation_LeaveFromRight;
[\SASRegistrationManipulation]
RemoveFromRight = number of digits removed from the right
side of the user part before saving to the registered user
database.
LeaveFromRight = number of digits to keep from the right side.
If both RemoveFromRight and LeaveFromRight are defined, the
RemoveFromRight is applied first. The registered database
contains the AoR before and after manipulation.
The range of both RemoveFromRight and LeaveFromRight is 0 to
30.
For example, the manipulation rule below routes an INVITE with
Request-URI header "sip:7184002@10.33.4.226" to user
"4002@10.33.4.226" (i.e., keep only four digits from right of user
part):
SASRegistrationManipulation 0 = 0, 4;
Notes:
You can only configure one index entry.
For a detailed description of the individual parameters in this
table and for configuring this table using the Web interface, see
''Configuring Stand-Alone Survivability'' on page 216.
