System Features – Operator and User

User Accounts

The account code feature allows a user to allocate a cost centre or account code to an incoming or outgoing call. Each extension can be programmed to have either mandatory or optional use of account codes. The information may be output in the call log to allow costs to be managed or to facilitate charging of call time to clients.

Automatic Answer

Feature Phones may be set to automatically answer incoming calls, only internal calls may be automatically answered.

Alternative Ring Cadence

The system provides different ring cadences for internal and external calls, allowing the user to know the source of an incoming call. The user may switch these cadences if required.

Background Music

The background music feature enables a Feature Phone user to listen to music through their Feature Phone speaker. The facility is available if the Options Module is used and an external music source is connected such as a CD player or Radio. The user may adjust the volume on the Feature Phone and the facility may be switched on/off at each individual extension. The feature operates when the phone is in an idle state and is suspended when the phone is used or a call is received.

Basic Analogue Phone Support

The LAKE OfficeLink supports the use of any approved Analogue 2-wire MF telephone. The majority of system features are accessible using standard telephones.


While on a call, a user may make a temporary Consultation to an internal or external party, they are returned to the original call on completion of the consultation leg of the call. Conference While on a call, a user may call a second party and initiate a three-way conference. The user may end the conference with all parties at the end of the call or alternatively choose to release one party from the call and continue with the other

Call Duration Indicator

When making External Calls from a Feature Phone the Call Duration is displayed in the Phone Menu

Call Deflection

A call, which is being presented, to an extension may be deflected by the user. The call may be deflected to another extension, a Work Group, a Voice Mail Box or to an external number

Call Divert

Calls to an extension or group may be diverted to another extension, a Work Group, a Voice Mail Box or to an external number. Calls may be diverted on the basis of – Divert All, Divert on Busy, or Divert on no Answer.

Call Pick up

An incoming call to the system or a specific group may be picked up at any extension by selecting the appropriate call pick up option

A call may be “Parked” in the system if required, this allows the call to picked up at another extension when required. The system supports up to 5 calls being “Parked”

Call Waiting

Call waiting tone/indication is provided when a second incoming call is received at an extension. Call Waiting tone is generated for both internal and external calls, and when presented to a Feature Phone the identity of the second caller is also presented. The extension may if required be protected from Call Waiting tone on either a temporary or permanent basis.

Caller Display (CDS/CLI)

Caller display information received from the Network will provide the number of the calling party to the called extension. This facility is known as CDS on the PSTN Network and CLI on the ISDN Network. The Network provider may provide this service on a subscription basis.

Numbers received into Caller Display may be saved into the system speed dial lists if required, the call may also be returned by selecting the number in the Caller Display list if required.

If the number is matched to an entry in the system speed dial list, the name of the calling party will be presented when a call is received.

CLI Routing

You may program the system to route calls from specific callers to predetermined extensions. This facility allows specific customers for example to be answered by the same person every time.

Call Logging

If your system is equipped with a Call Logging Interface Module, a printer or PC may be connected to your system, which will maintain a record of incoming and outgoing calls made on the system. Details are printed as the calls are completed.

Door Intercom & Relay

You can equip your system with a Door Intercom. The Door Intercom has a button which, when pressed, rings at programmed Extensions, and has a microphone/speaker for communication. With a Door Intercom fitted in your reception area, anyone visiting your premises can call when they arrive and you can speak to them before you let them in.

Your system also features a Doorstrike relay output, which can be used to operate a Doorstrike mechanism, to allow you open the door from your Extension. You must purchase the Doorstrike mechanism yourself and arrange for a qualified electrician to install it.

Display Messaging

The display messaging facility allows a user to leave a text message in their extension, this may be a standard system message or a bespoke message. The message is then displayed to any other caller who calls that extension from a Feature Phone

Do Not Disturb

Each extension may be set to Do Not Disturb, this ensures privacy for meeting times for example, as no calls are received when the feature is enabled. An internal caller from a Feature Phone will be advised that Do Not Disturb is enabled.

Day / Night Service

The system may be switched between day and night mode, this may be activated manually or on an automatic timed basis, for example out of office hours. Switching to Night mode allows calls to be routed using different rules outside office hours.

Extension Lock

Each extension may be locked with a personal PIN number required to make calls or to operate the phone. Emergency numbers only may be dialled when the Extension Lock is enabled

Extension Names

All extensions on the system may be allocated names, which may be individuals or departments for example. When making internal calls from a Feature Phone all names are displayed thus saving the caller the trouble of looking up extension lists.

External Calls

The system supports unlimited simultaneous external calls both incoming and outgoing from the system to the maximum capacity of populated lines

Extension Groups – Ring Group / Hunt Group

Extensions may be grouped in a logical work group to support Team activities or Departmental Groups. Internal or External calls may be presented to all phones in the Group, or the call may Hunt through the Group for the first available operator. Calls may be processed on a Linear, Cyclical or Longest Idle basis. The facility to allow Hunting within a Hunt group is also provided.

Extension Reset

Call Divert
Call Back
Display Messaging
Reminder Call

Feature Phone Support

The IP - Link supports 2 Feature Telephones, the CS and the ECS as described above in addition to the basic S Terminal

Follow Me

A user who is away from their extension may initiate a Divert from an extension close to them. In this case they create a Follow Me divert from the nearby extension which routes calls from their own extension to the one closest to their current location.

Flexible Numbering

The Extensions numbers, Line access digits, and first digit of the feature codes can be changed. This allows systems with DDI Numbers to have their extension number reflect the DDI number.

Headset Operation

The IP - Link system supports Headset detection, once a headset is connected to the Cs or ECS Terminal then the system operates in Headset mode. The terminal may easily be toggled between headset and standard mode of operation without removing the headset connection


The user may place Internal or External calls on Hold. The tone played to the held caller may be Silence, Tone on Hold, Internal Music Source or External Music Source (CD, Radio etc)

Hot Line

The Hot Line facility allows an extension to be programmed to dial a specific number as soon as the phone handset is lifted. This facility is useful to enable direct dialling from fax machines and to greet visitors to unattended reception areas.

Internal Calls

The system supports unlimited simultaneous internal calls between extensions


The Intrude feature allows the operator intrude on a line to line call, for example when an incoming call is transferred to an external party. This feature ensures that the operator has control over line to line calls.

Key System Operation

Typically used in smaller companies where call activity should be displayed on all Feature Telephones

Least Cost Routing [LCR]

Least Cost Routing allows the system to route calls through different Network Operators where the user has connections to multiple providers. The facility may be used to send calls through the most attractive route on the basis of the number called and the time of day. The feature may be activated on a Preferred or Exclusive basis and calls may be router with Carrier Pre Selection codes or through specific Network Lines.

NOTE: LCR may also be used to direct specific calls through VoIP service providers or a Private IP Network using the Internet Module or Private Networking Module

Manager – Secretary Association

It is possible to create logical work groups between for example a manager and secretary. This provides specific features for improved call handling and productivity.

Missed Call List

The missed call list stores information on the last 350 calls received into the system. Information may be recorded to a central store or to individual extension stores. Calls may be returned directly from this store and if required the numbers may be saved into the system speed dial store.

Outgoing Call Restriction

Each extension on the system may have outgoing call restrictions placed on it. Restrictions may be applied to restrict different call types at different extensions such as Local, National and International calls. The restriction may operate to different rules at different times of the day, for example no restrictions during the day and International calls restricted out of office hours. Emergency numbers may not be restricted.

Operation behind a parent PABX

The system may be configured to operate behind a parent PABX, for example where the system is used for one department in a larger organisation.

Power Failure

Your system can be equipped with an optional Battery Backup Unit (BBU). When equipped, full operation of the system is provided for at least one hour in the event of a power failure. If your system is equipped with ISDN access, it is recommended that this BBU be installed as calls can be received and made on the ISDN Lines if power fails.

Calls to the PSTN network may be made from specific extensions in the event of power failure, without the BBU module. These specific extensions must be populated with standard telephones and not Feature Phones to provide functionality in power fail situations.

Portable PIN

This facility enables the creation of 100 accounts with PIN code. These PIN codes can then be used to over-ride the Class of Service at any extension with the Class of Service assigned to the PIN code account. Calls made using a PIN are reported with the PIN number in the SMDR Call Log output.


The paging facility allows any authorised extension to page personnel from their extension. The paging facility may be used to page all Feature Phones or to page through a Public Address system.

PABX Operation

Typically used in larger systems, where an operator processes incoming calls and it is preferred not to show call activity on every Feature Terminal

Personal Speed Dial

Each Extension may have a Personal Store to record frequently dialled numbers. Up to 30 numbers may be stored for Feature Telephones and Standard Telephones

Room Monitor

All extensions (except the first 2 extensions) may be set into “Room Monitor” mode. When placed in this mode the extensions may be left “Off Hook” and then called from Extension 20 / 21 (default numbers for first 2 extensions). A caller from 20 / 21 will be connected to the “Room” all other callers will be returned Busy.


When making a call the reseize option allows the user to cancel the call and select the same line for another call


The redial feature allows the user to redial the last dialled external number, allowing for fast redial of busy numbers

Ring Back

A Ring Back may be initiated if the extension being called is busy or if all available lines on the system are busy when trying to make an external call. When initiated the system will call the user back when the extension becomes free or a line becomes free in the case of an external call.

Reminder Call

The reminder call function allows each extension to set a reminder call for any time within the next 24 hour period. The extension is called at the predetermined time and multiple calls will be made if the call remains unanswered.

Saved Number Redial

The Saved Number Redial function allows the user to redial the most recently called 6 external numbers

System Speed Dial

The System supports up to 500 System Speed Dial Numbers, which may be recalled from any extension, both Standard Phones and Feature Telephones.

System Programming

All system programming may be carried out from a Feature Phone, which has been allocated the programming extension. In addition the system may be configured either locally or remotely via the system management tool.


Calls may be transferred to another internal extension or to an external number. It is possible to restrict the extensions, which may transfer calls to external numbers

Tone Protection

An extension may be protected from Call Waiting tone if required to prevent disturbance to important telephone calls.

Time & Date

The system time and date may be updated on a daily basis by the Network operator if the facility is supported. The time and date may also be manually adjusted in the system if required. Time and date information is used for several facilities in the system including Call Logging, Voice Mail time stamping etc.

Specific ISDN System & network Features

If your system is equipped with ISDN access, there are a number of additional features available.

MSN / DDI Operation

MSN numbers may be programmed to ring individual Extensions allowing callers to dial through directly. You may also choose to allocate a number to a group of Extensions, so that a caller may dial through to that particular group.

Multiple Call Handling

You can programme more than one MSN/DDI number to ring at an extension. If a call is presented to your Extension while you are on another call you will hear a Call Waiting tone, provided your Extension is programmed to receive Call Waiting tones.

CLI Services

The Calling Line Identity Presentation (CLIP) service provides that, when you receive an incoming call on your ISDN Lines, the caller’s number is presented to the system. This number, (or name, if a name has been associated with the number), is displayed on all Feature Phones programmed to ring. It is also displayed on any standard phones capable of detecting CDS. In addition, you can store caller numbers, dial stored numbers, and route incoming calls to Extensions based on the caller number provided.


Calling Line Identity Restriction allows the user to stop their number being displayed when they call an external party. The feature may be permanently activated or activated on a specific call basis.


Connected Line Restriction allows you to prevent your number being displayed to an incoming caller. The feature may be permanently activated or activated on a specific call basis

Tele Secretary

The Tele-secretary feature allows you to use the names you have associated with the MSN/DDI numbers of your ISDN Lines, to have ringing Extensions display ‘Call for XYZ’, where XYZ is the name associated with the MSN/DDI number being called. When the call is answered and transferred, the Display of the Extension, to which the call is being transferred, will see the CLI number, (or name if programmed), as normal.

Network Divert

Network Divert is an ISDN service available from your ISDN Network Provider, which allows you to divert calls from an incoming ISDN Line. This service allows calls to be diverted in the Network, rather than tying up Lines on the PBX.

Network Call Deflection

The Call Deflection feature on the IP - Link system allows calls to be deflected in the Network. With this feature the call is presented to the IP - Link system, which may re route the call through the Network to another location or number. This keeps Lines free on the IP - Link system, while maintaining control over the routing of calls.

ISDN to the Desktop

The IP - Link can be equipped with an interface to an internal ISDN bus, which allows ISDN devices to use your system ISDN Lines.
