In the SIP MIB, locate the sipUAAuthUsrPwd variable in the sipUAAuthGroup.
12 Telephony Configuration This chapter explains how to set the telephony variables of the AT-VP504E FXS, i.e. the way the unit handles calls. Using Dial Maps A Dial Map is a very powerful feature that allows you to compare the number users just dialed to a string of arguments. If they match, users will be able to make the call. If not, users will not be able to make the call and will get a busy signal.
Chapter 12 - Telephony Configuration Using the Dial Map Special Characters Administration Manual (SIP/MGCP Version) If the result is over-qualified (i.e. no further digits could possibly produce a match), sends a fast busy signal. Dial Maps use specific characters and digits in a particular syntax. Those characters are: Table 39: Dial Map Characters How to Use a Dial Map Character Use Digits (0, 1, 2... 9) Indicates specific digits in a telephone number expression.
Chapter 12 - Telephony Configuration Administration Manual (SIP/MGCP Version) Combining Several Expressions in a Dial Map It is possible to combine two or more expressions in the same Dial Map by using the “|” operator, which is equivalent to OR. Let’s say you want to specify a choice: the Dial Map is to check if the number is internal (extension), or external (a local call).
Chapter 12 - Telephony Configuration Administration Manual (SIP/MGCP Version) [2-9]xxxxxxT Note: When making the actual call and dialing the number, the AT-VP504E FXS automatically removes the “T” found at the end of a dialed number, if there is one (after a match). This character is for indication purposes only. Using a Dial Map for Calls Outside the Country If your users are making calls outside your country, it may sometimes be hard to determine exactly the number of digits they will have to enter.
Chapter 12 - Telephony Configuration Administration Manual (SIP/MGCP Version) countryGroup section of the Provisioning MIB. Each of these Dial Map rules has seven (7) specific variables that you must define for the Dial Map to work properly. For example, the following are the variables associated with Dial Map #1.
Chapter 12 - Telephony Configuration Administration Manual (SIP/MGCP Version) Table 40: Dial Map Rules Variables (Continued) Variable Description apaUIMapRule1 PrefixEnable Indicates if digits are to be added to the number dialed by users when making the call.

Chapter 12 - Telephony Configuration Administration Manual (SIP/MGCP Version) Table 42: Dial Map Rules #2 Settings (Continued) Variable apaUIMapRule2RemDigit Count Setting 1 The first digit “1” in the dial map indicates a user wants to call outside his/her own Area Code. It has to be removed because it does not need to be expressed to the IP Communication Server. The IP Communication Server needs only to know the complete number of the called party (CC+AC+directory number).
Chapter 12 - Telephony Configuration Administration Manual (SIP/MGCP Version) Table 43: Dial Map Rules #3 Settings (Continued) Variable apaUIMapRule3PrefixDigit Setting 1 - Prefix Country code A valid telephone number must contain a Country Code, an Area Code, and a number.
