  Mediant 1000B Gateway & E-SBC 
Parameter  Description 
Note: The SIP Interface must belong to the SRD assigned to the rule 
(see the 'SRD' parameter in the table). 
Source IP Address 
src-ip-address 
[Classification_SrcAddress] 
Defines a source IP address as a matching characteristic for the 
incoming SIP dialog. 
The valid value is an IP address in dotted-decimal notation. In 
addition, the following wildcards can be used: 
  "x" wildcard: represents single digits. For example, 10.8.8.xx 
represents all addresses between 10.8.8.10 and 10.8.8.99.  
  Asterisk (*) wildcard: represents any number between 0 and 255. 
For example, 10.8.8.* represents all addresses between 10.8.8.0 
and 10.8.8.255. 
By default, no value is defined (i.e., any source IP address is 
accepted). 
Note: 
  The parameter is applicable only to Server-type IP Groups.  
  If the IP address is unknown (i.e., configured for the associated 
Proxy Set as an FQDN), it is recommended to classify incoming 
dialogs based on Proxy Set (instead of using a Classification rule). 
For more information on classification by Proxy Set or by 
Classification rule, see the note bulletin in the beginning of this 
section. 
Source Transport Type 
src-transport-type 
[Classification_SrcTransport
Type] 
Defines the source transport type as a matching characteristic for the 
incoming SIP dialog. 
  [-1] Any = (Default) All transport types 
  [0] UDP 
  [1] TCP 
  [2] TLS 
Source Port 
src-port 
[Classification_SrcPort] 
Defines the source port number as a matching characteristic for the 
incoming SIP dialog. 
By default, no value is defined. 
Source Username Prefix 
src-user-name-prefix 
[Classification_SrcUsername
Prefix] 
Defines the prefix of the source URI user part as a matching 
characteristic for the incoming SIP dialog.  
The URI is typically located in the SIP From header. However, you can 
configure the SIP header from where the device obtains the source 
URI, in the IP Groups table ('Source URI Input' parameter). For more 
information on how the device obtains the URI, see ''SIP Dialog 
Initiation Process'' on page 
649. 
The default is the asterisk (*) symbol, which represents any source 
username prefix. The prefix can be a single digit or a range of digits. 
For available notations, see ''Dialing Plan Notation for Routing and 
Manipulation'' on page 999. 
Note: For REGISTER requests, the source URI is obtained from the 
To header. 
Source Host 
src-host 
[Classification_SrcHost] 
Defines the prefix of the source URI host name as a matching 
characteristic for the incoming SIP dialog.  
The URI is typically located in the SIP From header. However, you can 
configure the SIP header from where the device obtains the source 
URI, in the IP Groups table ('Source URI Input' parameter). For more
