VOIP Digit MapIn contrast to the Digit Map feature for PSTN, the VOIP Digit Map feature allows VOIP callsmade with Leading Digits and Length of total dialed digits matching the rules specified to bedialed out immediately. As an example, let’s say a service subscriber frequently calls anothergroup of people whose VOIP phone numbers have the leading digits of 224 and a total length of4 (i.e. 2240 ~ 2249). By specifying in the VOIP Digit Map the leading digits of 224, and aLength of 4 in the VOIP Digit Map menu, this would alert the VOIP gateway device as soon asthe subscriber dials 224. The gateway device then sends the call out immediately when thesubscriber finishes dialing the 4 th digit, rather than wait for a time out period to expire whilewaiting for additional digits to be dialed.Figure 52 VOIP Call Digit Map Configuration WindowItem DescriptionLeading Digits Enter the prefix or leading digits of the telephone number(s) to be dialed.Length Enter the total length of the telephone number. “0” means the length is notfixed.Add/Modify Add or modify user desired prefix and length of the telephone number.Delete Delete an existing prefix and length of the telephone number from the DigitMap Table
