Automatic Number Translation
Introduction
• This feature is used to translate the dialed number string to the
number string which will be actually dialed out by the gateway. It is
applicable on Destination Port only. This feature is also called
Automatic Number Translation (ANT).
• This feature is useful for:
• Entering short number string for the frequently used number of
long number string.
• It is also useful for the application as mentioned below:
• If user wants to remember and dial Access code for only one
domain (say abc.com) instead of other Access code for some
other domain (say Pulver.com) while making an IP-Call.
• ANT is applicable for SIP accounts only.
For Example:
• Suppose the Gateway is so programmed that all the calls made to
abc.com are routed through the SIP trunk of Pulver.com. Now when
a customer makes a call to a number, say *1235678 (*123 is the
access code given by SE, for the domain viz. abc.com and 5678 is
the subscriber number), the system determines that the called party
is a subscriber of abc.com from the access code dialed.
• However, pulver.com does not consider *123 as the access code
for abc.com. Rather pulver.com specifies *777 as an access code
for abc.com which is not known to the caller. Hence, *1235678
needs to be replaced by *7775678, and ANT will be used for this.
How it works?
• Two number Lists are programmed: Dialed Number list and
Substitute Number list, programmed for the destination port.
• The number string in Substitute Number List is programmed at the
corresponding Index number of the Dialed Number List. For
example, if the number string programmed at the index “3” in the
dialed number list matches with the dialed number then the part of
the matched number string will be replaced with the number string
programmed at the index “3” of the substitute number list.
• After selecting the destination port for routing the call, the number
