50General FunctionsGeneral FunctionsAssignment of Internal and External CallNumbersYour telephone’s internal number is assigned when the systemadministrator configures the Forum 500 / Forum 5000 communicationssystem. The call number is linked to the call key g ofyour telephone, which means you receive calls on this key. Youcan have several internal call numbers on different call keys onyour system telephone. The external call number(s) at which youcan be reached is (are) assigned to the call key(s) (with the internalnumber).External telephonenumbersCall distribution schemeInternal telephone numberson the call keys4701 16784701 12344701 13454701 145647484950Telephone 1Telephone 2Communications system51Telephone 3Example of the assignment of internal and external call numbersThe above example shows that the system’s external call numbersare first stored in the Forum 500 / Forum 5000. The telephonescan be reached selectively by means of call distribution of thenumbers to the internal numbers (call keys). As you see,telephone 1 and telephone 2 both ring when a call is made to thenumber 4701 1234. At the same time, telephone 1 can also bereached on the number 4701 1678.Signalling on the Call Keys“Call key” is the general term for all keys of your telephone whichyou use to make calls and are called. These are feature keys(please refer to page 15 and page 15 also) or call keys with teamTelephoning

While you are making a call, new calls can bequeued. These callers first hear an announcement (if the systemadministrator has preset an announcement) and then the ringtone. The number of calls permitted in the call waiting queue isset by the system administrator during system configuration,5 calls for example. When this number is reached, further callershear the busy tone. The calls in the queue are put through inorder of priority (baby calls, door calls, VIP calls, other internaland external calls), irrespective of the order in which they camein.Calls that have been in the queue for too long are removed, andthe callers then hear the busy tone. The period of time until anexternal call is released is set by the network operator. In mostEuropean countries this is usually three minutes.Telephoning

52General FunctionsYour telephone can have a call waiting queue even if it belongs toa subscriber group, where it simultaneously affects call forwarding.If several call numbers are configured for your telephone (e. g. ontrunk or team keys), separate call waiting queues are used foreach number.On the Forum Phone 535) incoming calls are signalled by meansof a short tone (default setting); they are also indicated on thedisplay. The system administrator can switch off the notificationtone for a new call in the web configurator with the Beep forcalls in call queue option (menu: Telephony: Devices: Systemphones).If there are calls in the queue, the level indicator appears at thebeginning of the second line of the Forum Phone 535 display. Ifseveral call numbers with call waiting queues are configured foryour telephone, the total number of entries appears.For the System Administrator:The “Call Queue” chapter in the “Mounting and Commissioning”(Forum 523, Forum 525/526, Forum 550/560) resp. “Commissioningand Maintenance” (Forum 5050) guide explains how toconfigure call waiting queues and set up a enquiry station usingthis function.Accepting a Call During Automatic DiallingSample situation: You have entered a call number or selected acall number (in the call list, the re-dial list or the phone book). Thecall number is not yet dialled and you receive a call at thatmoment. When you pick up the handset the following operationsare possible:• The call number you entered is dialled.• You accept the call.The Prefer incoming connections option determines which ofthese operations is carried out. The system administrator configuresthis option in the web configurator, in the Telephony: Settingsmenu.Telephoning

General Functions 53Block Dialling/Automatic DiallingIf you activate the menu item 5 En-bloc dialling in the Menu-Card Phone settings, you can enter all call numbers (and corrector add digits to them, if necessary) without lifting the handset(see MenuCard “Phone Settings” starting on page 123). Thenumber is displayed in the info line. Entries from the redial list,the call list and the telephone book that are to be dialledusing O also appear in the info line first. The number youhave selected is not dialled until you lift the handset or press thehands-free/open-listening key L.If block dialling is switched off, the telephone switches to open-listeningmode as soon as you enter a call number and dial it.Note: An initiated automatic dialling is automatically terminatedafter 60 seconds if no further entries are made.Block Dialling and Headset OperationIt is useful to activate the “block dialling” feature when using aheadset (if you have activated this via the MenuCard Phone settings,see page 124). The call number entered will only be dialledonce you have pressed the headset key K.Once block dialling has been activated and the headset switchedon, the phone immediately switches over to headset operationand the call number is dialled when you enter a number on thephone.Dialling a Different User or a Different TerminalYou can also use your system telephone for dialout with a headset.To do so, save a destination call number on your system telephone(via the MenuCard Connections, the menu entry 2ƒDial:0ƒRemote dialling, please refer to page 130 also). The savedcall number will be dialled automatically when you press the headsetkey within 30 seconds. After 30 seconds, the dialout will bedeactivated automatically.This feature can be used on all devices for which the systemadministrator has configured a device ID.

If the menu item hasbeen activated, this programmed call number is dialled when aspecified period has expired (default setting is five seconds afteryou have lifted the handset). If you begin dialling a call numberwithin the specified period, the baby call is cancelled. The babycall can also be triggered by pressing the hands-free/open-listeningkey L, a call key g or the headset key K(requirement: the headset has to be turned on, see page 124).Your system administrator configures the baby call period from 0to 20 seconds for all subscribers on the Forum 500 / Forum 5000.Ask your administrator what the current value is.Announcements (with and withoutIntercom)Announcements can only be made to system terminals. For you tobe able to use this function, the system administrator must set upthe corresponding authorisation for you. Announcements can beset up on single or multiple system terminals. The “Announcement”function is available in two versions.• Announcement with intercom: the microphone of theterminal called is switched on and the person you are callingcan immediately answer your announcement (hands-freemode). An announcement with intercom can only beconducted to a single system terminal (not a group ofterminals).• Announcement without intercom: The called subscriberhears a special information tone followed by yourannouncement. In order to answer your announcement, thesubscriber has to take the call just like a normal call (pleaserefer to the section Responding to an Announcement onpage 82 also).If you make an announcement to a group of systemtelephones (e. g. to a hunt group number on which calls aresignalled simultaneously), all subscribers called hear theannouncement at the same time.

84Special Calls/FunctionsForwarding CallsTypes of forwardingYou can forward internal or external calls intended for yourself toanother internal call number or, provided that you have the necessaryuser group authorisation, to another external call number.Calls can be forwarded either immediately, after a specified periodof time (delay) or if the line is busy. You can configure more thanone call forwarding mode at the same time (Immediately, Afterdelay or Busy). You can, for example, configure call forwardingImmediately for external calls to one call number, and call forwardingAfter delay for internal calls to a different call number.During configuration, the system administrator defines an intervalin seconds for After delay call forwarding. You can replace thisdefault with your own individual value when programming Afterdelay call forwarding. If more than one forwarding mode hasbeen activated, Immediately is given priority.Call forwarding to a voiceboxIf Forum Voicemail, the integrated voicemail system, is installedin the communications system, you can also forward your calls toa voicebox configured for you.Selective Call ForwardingFurther, the system administrator can programme call forwardingwhere the call number of the caller is analysed (“SCF: SelectiveCall Forwarding”). Potentially this could be the reason why specificcalls do not reach you. If you have any questions concerning thisfunctionality, please consult your system administrator.Least Cost RoutingLeast Cost Routing (LCR) can be evaluated with call forwarding toexternal numbers, provided your system administrator has configuredLCR and its application in the Forum 500 / Forum 5000 correspondingly.Ask your administrator for the configuration applicableto you.Hunt group call numbersDuring system configuration, the system administrator can configurecall forwarding destinations for hunt group call numbers.Telephoning

Special Calls/Functions 85These destinations are called when all users of a hunt group arebusy and/or when a call is not accepted by any member of thehunt group within a certain time interval. You cannot view orchange this call forwarding on your device.In addition, the system administrator can determine whether youcan forward incoming calls to the hunt group call number or not. Ifthe system administrator does not permit call forwarding for yourhunt group call number, any call forwarding that you have programmedon your device is not carried out upon a hunt group call.Call forwarding chainsThe system administrator can configure the system so multiplecall forwarding instances can be linked one to another to form achain. A simple example: user A forwards to user B, who then forwardsto user C. A call for user A is then directly signalled touser C.A setting in your user group regulates which call number appearson your device when a call which has been forwarded multipletimes is signalled on your device: you will see either the callnumber of the last user who programmed the last call forwardingin the chain, or the call number of the first user in the chain. Thenumber displayed is also saved to the caller list for missed calls.The system prevents call forwarding chains from forming a loop,e. g. when the call forwarding destination refers back to the callforwarding source. When the system detects a call forwardingloop, no further call forwarding is carried out. This can mean that– despite call forwarding being programmed – calls are nonethelesssignalled on your device.A loop is also detected during call deflection. If you receive a callvia a call forwarding chain and wish to deflect it to a destinationcall number which is already in the call forwarding chain, a negativeacknowledgement tone is heard and the call signalling onyour device will continue.Contact your system administrator if call forwarding is not functioningas expected on your device. The system administrator isable to analyse call forwarding chains and eliminate any possibleconflicts.Telephoning

96VoIP TelephonesVoIP stands for “Voice over IP” and refers to telephony wherevoice data is transmitted via Internet Protocol (IP). VoIP enablescompanies to use existing company data lines without having tolay new telephone lines. To be able to use this technology, however,suitable devices which support it are necessary.The following IP system telephones are suitable, e. g.Forum IPhone 525 and Forum IPhone 535. These telephones offerthe same range of functions that the Forum Phone 525 andForum Phone 535 standard system telephones offer and are operatedin exactly the same way. The number of keys and their functionsand the displays are the same for both the standard and theIP system telephones. Key extensions can also be connected to IPsystem telephones (see also the chapter Key extensions startingon page 32).If your system administrator has configured an IP system telephonefor you, the following information will be of interest to you:• During some connections you may experience short breaks orhear an echo. This depends on the transmission quality of theline and is not due to your telephone functioning improperly.• If your telephone is being connected to the line or theconnection is interrupted (e. g. if the company network breaksdown), the required terminal software will be loaded (thetelephone “reboots”). This happens automatically and maytake some minutes. The telephone is ready for operation whenthe display shows the time and the internal call number. Thenyou may use the telephone as per usual.• When telephoning via connected headset, it is advisable towait a second after accepting an incoming call before youbegin to speak. This brief time interval is necessary to allowthe VoIP connection to be established between yourself andthe caller.VoIP Telephones

IP System Telephone Ports 97IP System Telephone PortsIP system telephones have additional ports not included with thestandard system telephones. Above the display on the back of thedevice there are two RJ45 jacks for connecting the data line(s).These ports are labelled LAN and PC. Depending on how yourworkstation is equipped technically, there are two options for connectingthe IP system telephone. Your system administrator willconnect the telephone for you. If for whatever reason the lines getdisconnected at some point, follow the steps below to reconnectthe telephone yourself.Option 1: Your Workplace Computer has a Network PortAvailable.Insert the network cable into the telephone’s LAN port and theother end of the cable into the available network port.Option 2: Your Workplace Computer has just One NetworkPort Available which is Used by Both Telephone and PC.The telephone can be looped into the existing network connectionvia its LAN and PC jacks. To connect the telephone, use a networkcable to connect the telephone to the PC, one end of which isinserted into the PC port of the telephone. A second networkcable is inserted into the LAN port of the telephone, the other endof which goes into the network port.The power supply of the telephone and the connected key extensionsis provided by the network feed (“Power over Ethernet”). Ifyour company network does not supply Power over Ethernet, thetelephone will require a separate power supply via an additionalAC adapter plug (product code 90035810; product name“Forum 500 power for keypad & FIP 525/535”). The AC adapterplug is plugged into the port on the base of the telephone. Thissymbol identifies this port. If there are one or more keyextensions connected to this telephone, the AC adapter plug is notplugged into the port on the base of the telephone but into theoutside key extension (insert it into the port with the symbol)and provides power to the entire device.Please note: Never operate an IP system telephone with PoEand AC adapter plug simultaneously!VoIP Telephones
