DEFINITY Eterprise Commuicatio Server Release 9 Guide to ACD Call Ceters 555-233-503 1 Automatic Call Distributio (ACD) basics Itroductio 1-1 Automatic Call Distributio (ACD) basics Itroductio This chapter gives a overview of the Automatic Call Distributio (ACD) feature. It describes basic ACD capabilities for the followig Avaya switches: DEFINITY Eterprise Commuicatios Server ad DEFINITY ProLogix (kow as Category A) DEFINITY BCS ad GuestWorks (kow as Category B). NOTE: The DEFINITY BCS ad GuestWorks systems use the ACD feature, but do ot support EAS, CAS, or the CMS. This chapter addresses ACD termiology, switches ad switch features, how the ACD processes calls, split queues, distributig ad hadlig calls, ad the ACD ad call maagemet systems. ACD termiology defies commo terms that are used throughout this book. The Switches ad Switch Features sectio defies switches ad ACDs ad explais how the followig features work: truks, truk groups, ad extesios; automatic-i processig; switch attedat; ad Direct Iward Dialig (DID) processig. The What the ACD does seectio discusses how the ACD uses Automatic-i ad Direce Iward Dialig (DID) to process calls. Split Queues defies a split queue ad explais how to set up call processig to a split, icludig aoucemets for calls i a split queue; aswer supervisio ad abadoed calls, itraflow ad iterflow, ad ight service for the ECS ad Geeric 3.

It also defies the split supervisor telephoe buttos. ACD ad call maagemet systems CMS ad BCMS describes how CetreVu CMS collects measured data o splits/skills, extesios, truks, truk groups, VDNs, ad vectors. This sectio also icludes switch features that affect CMS data, such as Hold, Coferece, Trasfer, Multiple Call Hadlig, ad so forth. Category A versus Category B The ACD feature is available with switches that are sized differetly ad allow for differet features to be implemeted. These differeces fall ito two categories: Category A icludes all varieties of the DEFINITY ECS ad DEFINITY ProLogix. Category A allows for all ACD-related features to be implemeted, accordig to what the customer purchases. Category A supports the CMS ad CAS adjucts. Category B icludes the DEFINITY BCS ad GuestWorks switch. Category B allows for all basic ACD-related features to be implemeted except for EAS ad CetreVu Advocate ad CetreVu Supervisor. Category B does ot support the CMS ad CAS adjucts. ACD termiology The followig terms will provide geeral familiarity with the ACD eviromet. Aget Aget I Multiple Splits/Skills Aget State Aoucemets CAS A aget is a perso assiged to oe or more splits/skills ad hadles calls to/from a extesio i those splits/skills. Depedig o the ACD software, a aget ca be a member of multiple splits/skills. Aget state is a term or code that represets the curret availability status of a aget. The term aget state also represets a user ability to chage a aget s availability withi the system. A aoucemet is a pre-recorded message delivered to a caller i queue requestig the caller to remai o-lie, promptig the caller for iformatio or directig the caller to aother destiatio. Whe a call is i queue, depedig o the legth of time i queue, a automatic recordig ca ecourage the caller to hag o, call back later, call aother umber, leave a message or ca be used with call promptig to direct the caller to specific destiatios. These aoucemets ca be scheduled to occur periodically. Cetralized Attedat Service. CAS is a system feature used whe more tha oe switch is employed. CAS is a attedat or group of attedats that hadles the calls for all switches i that particular etwork. Available oly with Category A.

CMS is a adjuct (basic software package or optioal ehaced software package) that collects call data from a switch residet ACD. CMS provides call maagemet performace recordig ad reportig. It ca also be used to perform some ACD admiistratio. CMS allows users to determie how well their customers are beig served ad how efficiet their call maagemet operatio is. Available oly with Category A. A call ceter provides a cetralized locatio where a group of agets or compay represetatives commuicate with customers via icomig or outgoig calls. The ACD ca distribute calls to agets i a split/skill i the followig ways: Direct (liear) Hutig EAD-LOA (Expert Aget Distributio-Least Occupied Aget) EAD-MIA (Expert Aget Distributio-Most Idle Aget) UCD-LOA (Uiform Call Distributio-Least Occupied Aget) UCD-MIA (Uiform Call Distributio-Most Idle Aget) PAD (Percet Allocatio Distributio) (Available with CetreVu Advocate oly.) Call Promptig is a call maagemet method that uses specialized call vector commads to provide flexible hadlig of icomig calls based o iformatio collected from the caller. Oe example would be where the caller receives a aoucemet ad is the prompted to select (via dialed umber selectio) a departmet or a optio that was listed i the aoucemet. Call Vectorig is a optioal software package that allows processig of icomig calls accordig to a programmed set of commads. Call Vectorig provides a flexible service allowig direct calls to specific ad/or uique call treatmets. CetreVu Advocate is a collectio of ECS features that provide ew flexibility i the way a call is selected for a aget i a call surplus situatio ad i the way that a aget is selected for a call i a aget surplus situatio. Advocate also icludes methods for automatig staffig adjustmets. Available oly with Category A. Direct Iward Dialig. DID is a process ivolvig calls comig ito the switch from the CO. The switch tha routes the calls directly to the appropriate extesio (as idetified by the last four digits).

DNIS is a feature of the 800 umber service that seds the dialed digits to the called destiatio. This ca be used with a display telephoe to idicate the type of call to a aget. For example, the call by its destiatio ca be classified as a certai type of call or caller (e.g., a Gold Card caller) depedig o a product or service the destiatio umber is associated with. Expert Aget Selectio. A optioal feature available with G2.2 ad ewer switches that uses Call Vectorig ad ACD i the switch to route icomig calls to the correct aget o the first try based o skills. Available oly with Category A. Telephoes coected to a PBX/switch via telephoe lies are referred as extesios. Extesios is also the term used to defie the 3, 4, or 5 digit umbers used to idetify the telephoe to the PBX/switch software for call routig purposes. A group of truks/agets selected to work together to provide specific routig of special purpose calls. Iterflow is used whe a split s/skill s queue is heavily loaded or whe a call arrives after ormal work hours. Iterflow redirects a call to a destiatio outside the local switch etwork (a differet switch system). Itraflow is used whe a split s/skill s queue is heavily loaded or whe a call arrives after ormal work hours. Itraflow ivolves redirectig a call to a destiatio withi the local switch etwork (the same switch system). Look Ahead Iterflow. LAI allows users to balace the call work load betwee multiple call ceters o separate switchig systems. LAI uses ISDN to allow multiple switches to commuicate ad iterflow whe appropriate. Available oly with Category A. Leave Word Callig is a system feature that allows messages to be stored for ay ACD split/skill ad allows for retrieval by a coverig user of that split/skill or a system wide message retriever. Malicious Call Trace. MCT allows a aget to otify a predefied party a malicious caller is o the lie. It also ivolves eablig a recordig device to record the call. Night Service is used whe a call arrives after ormal work hours. The call ca be redirected to aother destiatio such as aother split/skill, a extesio, the attedat, a aoucemet with forced discoect, or a message ceter. Night Service ca take oe of three forms: Hut Group (Split/Skill) Night Service Truk Group Night Service System Night Service

Queue Directory Number. QDN is a associated extesio umber of a split. It is ot ormally dialed to reach a split. The split ca be accessed by dialig the QDN. The QDN is also referred to as a split group extesio. If calls caot be aswered immediately, they are routed to a call collectio poit (split/skill queue or attedat queue) where calls are held util a split/skill aget or attedat ca aswer them. Calls are ordered as they arrive ad they are served i that order. Depedig o the time delay i aswerig the call, aoucemets, music, or prepared messages may be employed util the call is aswered. Service observig is a feature used to trai ew agets ad observe i-progress calls. The observer (split/skill supervisor) ca toggle betwee a liste-oly mode or a liste/talk mode durig calls i progress. A ability give to a aget to meet a specific customer requiremet or a call ceter busiess requiremet. Available oly with Category A ad EAS active. A group of extesios/agets that ca receive stadard calls ad/or special purpose calls from oe or more truk groups. Split/Skill admiistratio is the ability to assig, moitor, or move agets to specific splits/skills. It also ivolves chagig reportig parameters withi the system. A split/skill supervisor is assiged to moitor/maage each split/skill ad split/skill queue to accomplish specific split/skill objectives. A supervisor ca assist agets o ACD calls, be ivolved i aget traiig, ad cotrol call itra/iterflow. A threshold is a poit i time or criteria that determies a certai actio by the system. For example, the umber of calls i queue or the time calls sped i queue determies specific call treatmets, or you ca set the umber of rigs prior to aoucemets or call aswers. Truks are commuicatio chaels betwee two switchig systems or offices. Truks grouped together to provide idetical commuicatios characteristics are called truk groups. Truks withi truk groups ca be used iterchageably betwee two commuicatios systems or cetral offices i order to provide multi-access capability. A term or code that represets the curret status of a particular truk.

The sectio cotais the followig topics: Truks, truk groups, ad extesios Automatic-i processig defiitio The attedat Switch with attedat ad extesios Direct Iward Dialig processig with a example Automatic-i processig of ACD calls DID processig of ACD calls Call processig o a ACD switch. What a switch does A switch is a electroic device that processes icomig, outgoig, ad iteral calls ad coects them to the proper destiatios. The telephoe compay switch i your local area is called a Cetral Office (CO). A switch owed by a compay or orgaizatio processes icomig, outgoig, ad iteral calls. Throughout this chapter, the term switch is used to refer to a compay or orgaizatio s switch. Truks, truk groups, ad extesios Icomig calls to a compay first pass through the CO. The CO seds calls to the compay switch over truks (telephoe lies that carry calls betwee two switches, betwee a CO ad a switch, or betwee a CO ad a phoe). The CO receives dialed digits from the caller, processes the digits, ad seizes a truk that is assiged those digits. After the CO seizes a truk, it seds a cotiuig trasmissio to the destiatio phoe or switch, ad o other calls ca be set over that truk util the curret call discoects. Sice a truk ca carry oly oe call at a time, truk groups are usually created. A truk group is a group of truks that are assiged to the same digits. With a truk group, the CO receives the digits of a dialed phoe umber ad checks the truk group assiged to that umber to see if ay of the truks are available. The CO the seizes a available truk. As may simultaeous calls ca be made over a truk group as there are truks i that truk group. A truk group, therefore, ca carry multiple calls for the same phoe umber. Whe a truk group carries icomig calls (that is, calls made outside the compay s switch locatio) to the switch, the switch the coects the calls to their proper destiatios withi the compay.

DEFINITY Eterprise Commuicatio Server Release 9 Guide to ACD Call Ceters 555-233-503 1 Automatic Call Distributio (ACD) basics Switches ad switch features 1-7 The switches previously listed, i additio to coectig icomig calls to the proper destiatios, are also like private COs for compay employees. That is, employee phoes are coected to a switch by telephoe lies called extesios. Extesios are the assiged 3-4- or 5-digit umbers withi the switch software, ad these umbers become the employee phoe umbers for iteral (itra-compay) calls. Automatic-i processig Automatic-i processig is oe type of call processig. With automatic-i processig, the CO processes all of the digits of a icomig call. The CO the seizes a truk from the truk group, but sice processig is complete, the call coects directly to a destiatio idetified i the switch software. That destiatio ca be a phoe, a queue (i which callers wait to be aswered i the order i which their call was received), or special treatmet like a aoucemet. Switch attedat Icomig calls ca also go to a switch attedat. A switch attedat is a perso who maually routes calls to their proper destiatios usig a attedat cosole (which is like a call switchboard). Normally a attedat serves as a iteral operator who trasfers calls to the proper extesios. Ofte, a switch will have more tha oe attedat, ad all of the switch s attedats will aswer calls directed to the attedat queue, which holds calls util a attedat is available. The attedat queue receives iteral calls made from employee extesios, ad also receives icomig calls through DID processig ad automatic-i processig. Attedat call hadlig varies, depedig o the compay s eeds. However, if the attedat has a automatic-i umber, it will ormally be the umber published i the phoe book, ad the DID umber will most likely be used by off-site employees who kow oly the attedat s extesio umber. Cetralized Attedat Service (CAS) is a switch feature that eables attedats to be cosolidated at oe private-etwork locatio. The atteded locatio is called the CAS mai ad each uatteded locatio is called a CAS brach. At brach locatios, calls requirig attedat services route by way of Release Lik Truks to the mai locatio. Direct iward dialig processig With Direct Iward Dialig (DID) processig, icomig truks do ot coect the CO directly to a employee s phoe; istead, the icomig truks are pooled by the switch, ad this pool of truks is the shared by employee phoes. Extesio umbers may serve as the fial digits of employee phoe umbers for icomig calls. That is the CO may assig a 2-3- or 4- digit prefix to a truk group. The, whe a 7-digit employee phoe umber is dialed, the call is processed as follows: 1. The CO processes the prefix of the dialed umber, ad the seizes a truk i the truk group that is assiged that prefix. 2. The CO passes the remaiig digits of the dialed umber to the switch. 3. The switch recogizes the remaiig digits as a employee extesio umber ad seds the call to that extesio.

DEFINITY Eterprise Commuicatio Server Release 9 Guide to ACD Call Ceters 555-233-503 1 Automatic Call Distributio (ACD) basics What the ACD does 1-8 DID processig example As a example of DID processig, say that Employee A has the exteral phoe umber 538-1000 ad the extesio umber 1000. Employee B has the phoe umber 538-9999 ad the extesio umber 9999. The steps i completig calls to Employees A ad B might be as follows: 1. Employee A s cliet dials 538-1000. 2. The CO servig Employee A s compay idetifies the digits 538 (the commo prefix for all phoe umbers to that compay) ad seizes Truk 1 i the truk group assiged the digits 538. 3. The CO passes the digits 1000 to the switch at Employee A s compay. 4. The switch idetifies the digits 1000 as Employee A s extesio umber ad seds the call to Employee A s extesio. 5. Employee A s phoe rigs ad Employee A aswers. 6. Meawhile, Employee B s cliet dials 538-9999. 7. The CO idetifies the digits 538 ad seizes Truk 2 i the truk group assiged the digits 538. 8. The CO passes the digits 9999 to the switch. 9. The switch idetifies the digits 9999 as Employee B s extesio umber ad seds the call to Employee B s extesio. 10. Employee B s phoe rigs ad Employee B aswers. While Employees A ad B cotiue to talk, Truks 1 ad 2 i the 538 truk group will ot accept ay more calls, so aother call begiig with the digits 538 will seize yet aother truk i the truk group. What the ACD does Automatic Call Distributio (ACD) is a switch software feature that processes high-volume icomig, outgoig, ad iteral calls ad distributes them to groups of extesios called hut groups or splits. The switch also seds iformatio about the operatio of the ACD to the CetreVu CMS which stores ad formats the data ad produces real-time ad historical reports o ACD activity. For more detailed iformatio about ACD, read the feature descriptio i the product documetatio that came with your switch. ACD is used by a call ceter to route icomig calls to specifically assiged splits/skills ad agets. ACD allows a system admiistrator to create a efficiet call maagemet eviromet. This admiistrator ca add or remove splits/skills from the system, add or remove aoucemets, add or remove agets, add truk groups ad route calls to the appropriate splits/skills. The admiistrator ca also specify ACD measuremet criteria ad use a optioal CMS package to provide reports o ACD efficiecy.

DEFINITY Eterprise Commuicatio Server Release 9 Guide to ACD Call Ceters 555-233-503 1 Automatic Call Distributio (ACD) basics Split queues 1-9 Thigs to kow before you start A voice respose port or a perso who aswers ACD calls is called a aget. Compaies that operate high-volume call-aswerig ceters, for example, a catalogue sales ceter, a reservatios ceter, or a customer service ceter, use the ACD feature to process icomig calls ad distribute them to agets. I additio to agets, each ACD split ca be assiged a split supervisor. The split supervisor uses various switch ad CetreVu CMS features to moitor split ad aget performace ad to provide assistace if ecessary. Maitaiig truks from the CO to the switch ad hirig agets to aswer calls costs moey. However, if customers who call to purchase goods or services have difficulty reachig a aget ad, therefore, stop tryig to get through, the call ceter loses reveue. Call ceter maagemet eeds, therefore, to determie how may truks ad agets are ecessary to miimize costs ad maximize the ability of customers to purchase goods or services. Maagemet ca the set up ad maitai the ACD accordigly. Automatic-i processig of ACD calls Through switch admiistratio, each automatic-i truk group is assiged to a ACD split. All calls that come i o a automatic-i truk group are directed to the assiged split. The the ACD software distributes the calls to the aget extesios assiged to the split accordig to the assiged call distributio method (described later). DID processig of ACD calls The switch eables you to dial directly to various extesios such as a VDN, a hut group, a aget, or a logi ID. Each extesio ca be assiged to a split as a DID extesio. For DID processig, truk groups are ot assiged to the split. The creatio of associated extesios is sufficiet to sed calls arrivig over DID truk groups to the appropriate split. Each split ca receive icomig calls through DID processig, automatic- i processig, or both. Automatic-i truk groups carry calls oly to the split, whereas DID truk groups carry calls to ay extesio idetified i the switch software, ot just a split. Split queues This sectio defies a split queue ad explais how to up call processig to a split.
