Prefix to Domain Name Conversion
What’s this?
• The Gateway routes the call to the IP network using the SIP
Account number from different Domain (SP) determined by the
routing mechanism.
• This Domain Name is identified by some prefix code number.
• The prefix code information is provided by the SE.
For Example:
• Suppose the Gateway is so programmed that all the calls made to
abc.com from FXS port are routed through the SIP Account
Pulver.com. Now when a user makes a call to a number, say
*2349874. Here *234 is the prefix code for the domain, abc.com
which is provided by SE and 9874 is the subscriber number.
• Thus by the prefix code dialed, the gateway determines that the
called party is a subscriber of abc.com.
• SE provides a table for prefix code to domain name to the user.
The table will look as shown below:
Index Prefix Domain Name
01 *234 abc.com
02 Blank Blank
:
Blank Blank
64 Blank Blank
How it works?
• The Table consists of entries for Prefix code and Domain Name.
This Table is not checked for making an outgoing call.
• This table will be checked when some FXS port has set Call
Forward and only Number is programmed i.e. not with Domain
name or IP address or user is doing Blind Transfer.
• The number dialed is compared with the ‘number’ in table using
‘Best Match’ found logic.
• If the match found, the digit is stripped off and domain name is
added to the number.
