Section 700 - Operation Chapter 6. DSLT Features576-36-700 DBS 576 (USA) issued October 2000 6-5• FF3 (Extension): Extension Class of Service Assignment• FF8 (Maintenance): Absence MessagesConsiderations• Calling parties without a display get a busy signal, rather than the Absence Message.• Regardless of setting an Absence Message on a DID/DIL extension, DID/DIL calls are routedaccording to the trunk ringing setting.• An absence message may also be cancelled by dialing 7**. This cancels Do Not Disturb and CallForwarding-All Calls as well.Account CodesDescriptionYou can assign account codes to clients to facilitate billing and to track call dates and times, numberscalled, and outside line numbers used. This information is printed for each account on the SystemMessage Detail Recording (SMDR) record. In addition, verified account codes may be used to changethe TRS level to allow calls to numbers otherwise restricted.Account codes may be either forced or unforced (voluntary) and either verified or unverified.This feature works with SMDR. During a phone call, a station user can silently enter an accounting orclient billing code. The entered Code will display on the phone’s LCD as it’s dialed, so the user cantell it’s being registered. Then later, the SMDR reports will show the Code dialed for each call, andeven sort the report by these Codes.There are two different types of account codes: Non-Verified and Verified Account Codes. Prior toVersion 3.6, the maximum amount of account code numbers for both types could range from 1-10digits. Beginning with Version 3.6, a second mode has been added that allows the user to set themaximum amount of account code numbers from 1-4 digits. An account code error will occur whenmore than the maximum number of digits are entered.Non-Verified Account CodesNon-Verified Codes are not checked by the system for validity. Depending on the setting, the user canenter anything from 1-4 digits or 1-10 digits. Individual phones can be programmed to accept forcedAccount Codes (the user must enter a code for every call) or voluntary Account Codes (the user canenter a code, but doesn’t have to, for each call).Non-Verified Account Codes can be assigned to incoming and/or outgoing calls. For incoming calls,the user can enter the Code anytime during the call. For outgoing calls, the user either enters the Codebefore accessing an outside line (for forced Codes), or anytime during the call (for voluntary Codes).Verified Account CodesVerified Account Codes entered by phone users must match a 4-digit code that has beenpreprogrammed into an Account Code Table. Depending on the setting, the user can enter anythingfrom 1-4 digits or 1-10 digits. These codes can also be either forced or voluntary. You can programthese codes with their own Toll Restriction Service (TRS) Class assignment so that, when entered,they will override the extension’s TRS Class. Thus, Verified Account Code users can “float” fromphone to phone, placing calls that would normally be restricted on that phone.
