Working with 'Call hold', 'Call transfer', 'Three-way conference' services

'Call transfer' service operation requires that the subscriber terminal party supports FLASH transmission via SIP using SIP-INFO, RFC2833 methods. Also, the subscriber terminal party should have an inband, SIP-INFO or RFC2833 DTMF signal transmission methods configured; make sure that the similar method is selected in the subscriber SIP profile configuration. 

'Call tranfer' service configuration example

Subscriber A calls Subscriber B; Subscriber B may press FLASH during conversation to put the Subscriber A on hold, at that time, 'Music on hold' will be played to the subscriber A, and Subscriber B will hear 'PBX response' tone; at that, timeouts for dialling the Subscriber C number will be activated, their values are provided below. After the number dial and Subscriber C replу, the options are as follows: 

While being in a call state with a Subscriber A, put him on hold with hook flash (R), wait for 'PBX response' tone and dial a Subscriber C number. When Subscriber C answers, the following operations will be possible: 

• R 0 – disconnect a subscriber on hold, connect to online subscriber;
• R 1 – disconnect an online subscriber, connect to subscriber on hold;
• R 2 – switch to another subscriber (change a subscriber);
• R 3 – three-way conference;
• R 4 – call transfer. Voice connection will be established between Subscribers A and C;
• Hangup – call transfer. Voice connection will be established between Subscribers A and C. 

'Call transfer' service timeout – at the moment, these timeouts are at their default values; their configuration will be implemented in future firmware versions. 

• First digit dial timeout: 15 seconds.
• Next digit dial timeout: 5 seconds.
• Busy tone timeout: 60 seconds.

'Redirection' service

'Redirection' service configuration may be performed using the corresponding setting in 'SIP subscribers'/'VAS management'/'Required subscriber selection' menu of the web configurator (see section VAS management) or using VAS management from the phone unit (according to RD-45), this method is described below. 

VAS configuration from the phone unit (according to GOST 45.49-96)

The subscriber may activate or deactivate the service themselves by dialling specific prefixes on their phone unit. Redirection service prefixes are configured in the dial plan (section Dial plan) add a new prefix with the 'Prefix type'/'VAS prefix' value. 

For VAS, it is recommended to use the following prefix values: 

Call forward uncoditional (CF Unconditional)

• Activation (*21*x.#);
• Deactivation (#21#);
• Control (*#21*|*#21*x.#).

Call forward on busy (CF Busy)

• Activation (*22*x.#);
• Deactivation (#22#);
• Control (*#22*|*#22*x.#).

Call forward on no reply (CF No reply)

• Activation (*27*x.#);
• Deactivation (#27#);
• Control (*#27*|*#27*x.#).

Call forward on out of service (CF Out Of Service)

• Activation (*62*x.#);
• Deactivation (#62#);
• Control (*#62*|*#62*x.#).

Call forward on time (CF Time) 

• Activation (*28*x.#);
• Deactivation (#28#);
• Control (*#28#|*#28*x.#).

Digits 21, 22, 27, 62, 28 may take up any arbitrary value; these examples feature recommended values. 

'Call transfer' service timeouts are at their default values at the moment; their configuration will be implemented in future firmware versions: 

• Call forward on no reply (CF No reply): 10 seconds;
• Call forward on out of service (CF Out Of Service): 10 seconds.

Example of VAS configuration from the phone unit 

Objective

The subscriber should configure unconditional forwarding to the number 222333444.

Actions

1. To activate the service, the subscriber should dial *21* and hear the 'PBX response' tone in response. 
   
2. To check the service activation, the subscriber should dial *#21*. If the service is active, the subscriber will hear the 'PBX response' tone. If the service is inactive, the subscriber will hear the 'busy' tone. 
3. To define the forwarding number, the subscriber should dial *21*222333444# and hear the 'PBX response' tone.  
4. To check whether the service has been activated for the specific number, the subscriber should dial *#21*222333444#. If the service is active and the dialled number matches the previously defined number, the subscriber will hear the 'PBX response' tone. If the service is inactive or the dialled number does not match the previously defined number, the subscriber will hear the 'busy' tone. 

To deactivate the service, the subscriber should dial #21#. 

Example of VAS configuration for 'Call forward on time' 

Objective

The subscriber should schedule time forwarding from 12 to 2 p.m. from Mon to Fri to the phone number 222333444.

Actions

1. In the Internal Resources → Scheduled routing section, create and/or edit the schedule by checking the boxes for those hours and days of the week when redirection should work, for this example these are columns 12, 13, 14 for the lines Mon, Tue, Wed, Thu, Fri. 
2. In the settings of SIP subscriber on which you want to configure forwarding, enable call forward on time. 
3. Абонент задает номер для переадресации и расписание, настроенное в п.1 набором * 28 * <number> * <shedule_idx> #, where:
   <number> – number to which the call will be forwarded 
   <shedule_idx> – schedule index according to which redirection will be performed 
   For this example, the dial will look like this: *28*222333444*0#
4. You can check that the service is activated by dialing *#28# or *#28*222333444*0#. If the service is activated, the dialed number and the schedule coincide with the previously specified one, then the subscriber will hear a dial tone. If the service is not activated or the dialed number and schedule do not coincide with the previously set one, the subscriber will hear a 'busy' signal. To deactivate the service, the subscriber should dial #28#. 

Conference with sequential participant collection (Conference)

This service allows the initiator to establish the conference by consequently adding participants using subscriber hold feature. 

When the initiating subscriber hangs up, the rest of the participants receive a ‘Busy’ signal if the initiating subscriber has ‘Disconnect conference by initiator’ option enabled. If VAS is diasbled, then when the initiating subscriber hangs up, the conference will continue to work. The maximum number of participants for all collected conferences for SMG-1016M is 40, for SMG-2016/3016 – 160. One conference can have no more than 40 participants. For example: on the SMG-1016M you can gather one conference for 40 participants, 10 conferences for 4 participants, etc. On SMG-2016/3016 you can gather 4 conferences of 40 participants, 10 conferences of 16 participants, etc. 

This functionality can be activated both on analog phones using the R key (short hang up (FLASH)) and on SIP phones using the CONF&TRANSFER/HOLD keys). 

Access to the service is managed by the 'Conference' checkbox. 

where:

<NUMBER N> – number of the subscriber participating in a conference;

<CONF> – conference call state;

<RS> – station response signal, waiting for dialing of the subscriber who needs to be added to the conference; 

R – short hang up (FLASH), if your telephone does not have a FLASH button, you can use the * or # buttons. To do this, you need to set the option ‘HOLD by’ flash/*/# in the sip profile in the DTMF reception/transmission section;

• For the service to work, the presence of the VAS ‘Conference’ prefix in the dial plan is required. 
  
• For the service to work, the ‘Call Hold’ and ‘Conference’ options should be enabled in the VAS block in the SIP subscriber settings. 
  

An example of using a conference call with sequential dialing, when subscriber A gather subscribers B and C into a conference:

Subscriber A makes a call to *71# and hears the welcome message “Welcome to conference", then puts the conference on hold <R> and dials the number of subscriber B, when subscriber B accepts the call, the connection between A and B is disconnected and they are both added to conference, subscriber B hears a welcome message, after which the subscribers A, B are in the conference.

Subscriber A puts the conference on hold again <R> and dials subscriber C number, when subscriber C accepts the call, the connection between A and C is disconnected and they are both added to a conference, subscriber C hears a welcome message, after which subscribers A, B, C are in the conference. 

Functionality description for SIP telephones

Where:

<NUMBER N> – subscriber number – participant in the conference call; 

<STATE> – conference call status; 

CONF – conference (should comply with RFC 4579 and the conference number should be identical to ‘Conference’ prefix in the dial plan); 

HOLD –  call on hold;

TRANSFER – call transfer.

• For the service to work, the presence of the VAS ‘Conference’ prefix in the dial plan is required. 
• For the service to work via ‘HOLD’, the ‘Call Hold’ and ‘Conference’ options should be enabled in the VAS block in the SIP subscriber settings. In addition, enable ‘Call Transfer’ in the SIP subscriber settings, increase the number of lines to 2, for the initiating subscriber for the conference collection scenario via CONF&TRANSFER. 

Example of collecting a conference for a SIP phone via CONF&TRANSFER:

Collection from the conversation:

• А makes a call to B, B answers.
• A presses the CONF button on the phone. 
• Both numbers are included in the conference, the conference is gathered. 
• Adding subsequent participants: 
  
  • A presses TRANSFER, dials C, C answers and gets into the conference; 
  • The station hangs up the A-C call; 
  • A releases the conference from hold (CONF) – now all subscribers are in the conference;
  • Or A does not release the conference from hold and immediately makes a transfer (TRANSFER) to the next subscriber D (adds to the conference) and so on. 

Collection with CONF button:

• A presses CONF, thereby making a call to *71# and hears the welcome message ‘Welcome to the conference’; 
• Adding subsequent participants: 
  
  • A presses TRANSFER, dials B’s number, B answers and gets into the conference; 
  • The station hangs up the A-B call; 
  • A releases the conference from hold (CONF) — now all subscribers are in the conference;
  • Or A does not release the conference from hold and immediately transfers it to the next subscriber C (adds to the conference) and so on. 

Call pickup

This service allows to answer the call directed to another subscriber.

Access to service is managed by the VAS 'Call pickup' checkbox. 

Where:

<NUMBER> – number of the subscriber for call pickup. 

Intercom and paging calls

This service allows the subscriber to perform the call with automatic phone unit response at the call party B. Note, that used phone units should support Answer-Mode: Auto for RFC 5373.

Access to service is managed by the VAS 'Intercom' checkbox. 

Where:

<NUMBER> – number of the intercom call subscriber. 

Paging call service operates in the similar way to the intercom call but it enables calls to subscriber groups using the conference number. For that, define the call group with the conference number in call group (see section Hunt groups) and add all subscribers using this service into it. 

Where:

<NUMBER> – conference number of the paging call.

Pasword aactivation/deactivation, restricted by password

These services provide the opportunity to override restrictions on access to outgoing calls (controlled by ‘Outgoing calls restriction’ service).

For example, if a restriction is set on outgoing communication, then the ‘Resrricted by password’ service makes it possible to cancel the access restriction only for the next attempt to establish an outgoing connection. The ‘Password Activation’ service cancels/sets a restriction on outgoing communication for all subsequent outgoing communication attempts. 

The access to the service is managed by checking the ‘Password activation’ box in VAS activation window.

The access to the ‘Restricted by password’ service is managed by checking corresponding box in VAS activation window. 

Where:

Access to service is managed by checking the ‘Reset all services’ box in VAS category checkbox. 

Follow me

With the ‘Follow me’ service, you can enable call forwarding for all calls from your telephone set to a remote one, using the remote phone. Service use example: a subscriber located outside their workplace wants to activate call forwarding for all calls from their work telephone set to a telephone set which is now ‘at hand’. 

Usage

Service activation:

The service involves two telephone sets: local and remote. The subscriber wants to forward all calls from the local telephone set to the remote telephone set. 

To do this, first of all, the subscriber should activate the service with or without PIN on the local telephone set (i. e. while being in the workplace the subscriber should enable the use of the service). After that, the subscriber, using their remote phone, can enable call forwarding from the local telephone set to the remote telephone set (if the service activation involved a PIN code, then you will have to enter the PIN; otherwise, the PIN is not needed) 

Service deactivation:

Remote call forwarding can be turned off from both remote and local telephone sets. You can deactivate the service only from the local telephone set, with or without a PIN-code. 

Service management from the telephone set

Where:

• PIN – a secret digital code consisting of 4 characters; 
• LOCAL_PHONE – the phone number from which the calls will be forwarded.

Follow me no response

Description

Using the ‘Follow me (no response)’ service, you can forward all calls from the local number to the remote number, if a call to the local number has not been answered within the specified time interval. 

Usage

The service involves two telephone sets: local and remote. The subscriber wants all calls that come to the local phone and have not been answered within the specified time interval, to be forwarded to the remote telephone set.

Activation/deactivation of the service is performed only on the local phone number. Request for call forwarding is performed on the remote phone.

Where:

• PIN – a secret digital code consisting of 4 characters; 
• LOCAL_PHONE – the phone number from which the calls will be forwarded.

Call park to

Description

The ‘Call Park to’ service is intended for placing a call on hold by one subscriber and removing it from hold by another subscriber. 

Placing a call into a parking slot is done by performing an unattended transfer during a conversation to the number of the code for placing a call in the slot. 

Example of usage

It is necessary to put the subscriber on hold in parking slot number 15. 

• During the call, a transfer is made to the number *57*15#.
• Another subscriber can remove the subscriber from this parking slot number 15 by calling *58*15#.

Service management from the telephone set

Where:

PARKING_SLOT_NUMBER – number of the parking slot in which the subscriber should be placed. If you dial *57# on your telephone, then PARKING_SLOT_NUMBER = number of the initiating subscriber placing into the slot. 

Voice mail

Description

The ‘Voice Mail’ service allows subscriber A to leave a message to subscriber B (call from A to B) in case subscriber B is unavailable/does not answer.

After fully listening to a new message, it is marked as old. Also, a message is marked as old if the user presses the digit 1 (go to the next message). 

Upon activation, the following voice mail options are available to the subscriber: 

• Unconditional – unconditionally forwarding an incoming call to the subscriber's voice mail; 
• No-reply – forwarding an incoming call to voice mail if the subscriber does not answer; 
• Busy – forwarding the incoming call to voice mail when the subscriber is busy; 
• Out of service – forwarding an incoming call to voice mail when the subscriber is unavailable; 
• DND – forwarding an incoming call to voice mail if the Do Not Disturb service is activated. 

Message playing:

To play voice messages, the subscriber dials the code *90# from his/her own phone, dials the code *91# from someone else's phone, and then enters the voice menu. 

Usage example:             

To activate voice mail, it is necessary to enable the Voice Mail of the VAS for the subscriber. 

Next, in the ‘VAS Management’ set the desired mode of operation: 

Now, when a call is received by this subscriber, messages will go to voice mail, and the subscriber will be able to listen to them by dialing *90# on their telephone and following the prompts of the voice menu. 

The subscriber can also set up the voice mail operating mode, using the voice menu and following its prompts. 

From the voice menu, the subscriber can: 

• Listen to voice messages 
• Delete voice messages 
• Change the voice mail mode 
• Set a password for voice mail.

One touch record

The service allows the subscriber to start recording a conversation during a conversation. 

Use case:
