Refer to Making and receiving phone calls on page 22 for details. If any of the above checks have failed, then refer to Troubleshooting on page 62 for more information.
IP Telephone User Guide 5 Making and receiving phone calls This chapter describes how to use the Flexor 500 to make and receive phone calls. Receiving calls Receiving phone calls on the Flexor 500 is extremely straightforward, but there are some features to note: The line indicator will flash to indicate which line the incoming call is received on. The number of the caller (and possibly the name) will be displayed on your telephone.
IP Telephone User Guide The display shows the dialled digits as they are entered. If an incorrect digit is pressed then the C button can be used to delete the last digit. After entering the digits for the number press the Call soft key to dial the number. A set of valid number formats and lengths may have been configured based on your region by your service provider. The number will be dialled automatically when a recognised pattern has been entered.
IP Telephone User Guide Selecting names It is possible to search the list of contacts in two different ways. The quickest method is to type the first few letters of the name using the numeric keys. These behave in a similar way to predictive text on a mobile telephone. The search tries to match the first part of each name so that you can search using the first name or the surname. Suppose you wished to search for Charles Jones. The predictive text letters for Charles relate to the numbers 2 then 4.
IP Telephone User Guide Call history The Flexor 500 holds lists of recent calls received and made. A maximum of 60 calls can be stored. These are held in temporary memory and will be lost if the device is reset. The call lists are accessed through the Call History menu item on the main menu. This leads to a screen with a list of different types of calls. There are five options on this menu. The first three provide access to lists of the missed, received and outgoing calls.
IP Telephone User Guide Ending calls At the end of a call there are two ways to disconnect. If there is only a single call active this can be ended by hanging up the receiver. When using the speaker or headset the appropriate button should be pressed to terminate the call. This disconnects all calls including any that are on hold. If you only wish to terminate the current call then press the C button. Other calls that are on hold are not affected and will remain on hold.
IP Telephone User Guide Using the address book You can dial a number from your PC using the Flexor 500 built-in Address book. Follow the procedure below: Click on the Voice Connect application icon to display the Flexor 500 management web pages. Click on the Address Book link. The Address Book page is displayed containing the names and numbers of your contacts. Click on the number you wish to call. The phone will dial the number and activate the speakerphone or headset.
IP Telephone User Guide 6 Using advanced phone features One of the advantages of VoIP is that it offers advanced telephony features such as: Putting a call on hold Transferring calls Do not disturb Call divert Forward calls Conference calls Voice mail Call waiting This chapter describes how to use the above features with your Flexor 500. Putting a call on hold The simplest way to put an active telephone call on hold is by using the hold button.
IP Telephone User Guide Attended transfer – where you speak to the recipient of the transferred call before transferring the incoming call to them. Blind transfer – where you transfer a call immediately without speaking to the recipient of the call (the transferee). Attended transfer The attended call transfer is simple. The procedure to follow is: 1. The phone rings, and you pick-up to speak to the caller. 2. You decide that they need to be transferred to another person. 3.
IP Telephone User Guide Do-not-disturb The Do-not-disturb feature has a button with an associated LED to indicate the state. The call features menu has a screen to set the Do-not-disturb feature. It has simple options to enable and disable the feature. When the feature is enabled the LED is illuminated and any incoming calls are diverted to voicemail. You can tell if Do-not-disturb is enabled by examining the LED indicator next to the button. This is illuminated when the feature is enabled.
IP Telephone User Guide Forward busy If an incoming call arrives while the telephone is busy the new call can be automatically forwarded to another extension. It is also possible to forward calls to a voicemail account. If there are multiple lines configured then any incoming calls will still be forwarded when there are active calls on any of the lines. This feature is configured using the Forward Busy call feature option.
IP Telephone User Guide Conference calls (3 Way Calls) This feature allows three people to take part simultaneously in a conference. The feature is accessed during a standard call by pressing the Conf soft key to start a conference. This provides an option to enter a number for the third party. Enter the number for the new call and press the Conf soft key to dial the number. The original caller is placed on hold.
IP Telephone User Guide Voicemail Most ITSP companies provide a voicemail facility so that callers can leave messages if the call is not answered. The Flexor 500 shows when there are voicemail messages waiting using the MWI (Message Waiting Indicator) LED. If there are new messages then a soft key in the default screen changes to show this. An extra line of text is shown below the current time with the number of new messages.
IP Telephone User Guide In this second example there is a conference with Laura Jones and Andrew Wilson. There was a missed call on line 3. Call Waiting When multiple lines are enabled several calls can be in progress simultaneously. An example is where a call is in progress and a second incoming call arrives. An indication of the incoming call is provided through the line buttons and it is possible to switch between the two calls. There is an option on the call features menu to disable this feature.
IP Telephone User Guide 7 Managing the device from the menus The menu system on the Flexor 500 provides a convenient way to adjust most of the settings. Certain aspects such as the SIP accounts and other advanced settings are only available through the web interface described on page 44. Many of these are configured by the service provider to the correct values and set to prevent a user altering them.

IP Telephone User Guide The RTP and SIP DSCP are used by some service providers to give priority to voice traffic over other network traffic. The values are 6 bits in binary with a standard value of 001100. The values should be entered as a series of binary digits using 1 and 0. When the values have been set use the Apply soft key to store the new settings. Region The region settings cover the country code, time zone and time format. These may have been set by your ITSP.
IP Telephone User Guide Screen The screen has a backlight feature to make it easier to see in certain lighting conditions. This is activated while the phone is being used and switches off after a period of inactivity. The brightness of this backlight can be set for a personal preference. The value is shown as a percentage. In addition the backlight can be disabled if desired. The brightness value is entered using the digits. The settings must be applied before the change will be observed.
IP Telephone User Guide There are also options to set the audio codec and DTMF mode. These should not require adjusting for normal use. If your device has been configured by a service provider then the DTMF option might not be available as this value has already been set correctly. Codec selection The codec screen provides an option to specify the permitted audio codecs and which one is preferred. These settings should not usually need changing and may have been locked by your ITSP.
IP Telephone User Guide The item to change is selected using the up and down arrows. The Chnge soft key is used to alter the selected item.
