Para criar um intercon é necessario atribuir uma linha em cada um dos dois telefones para operar como uma linha/botão de Intercom.
Pressionando o botão que foi atribuido para Intercom seleciona-se a linha e aciona a função de discagem automática para o segundo telefone. O telefone receptor recebe a chamada de intercom em sua linha previamente atribuida,essa linha auto-atende à chamada e ativa o telefone no modo viva-voz e aciona um beep e também força o viva-voz em mute para proteger a privacidade do destinatário de intercom.O caminho de áudio é aberto a partir do iniciador da chamada para o receptor.
Para atender à chamada de intercom, o destinatário simplesmente pressiona a tecla mute para ativar o caminho de áudio para o remetente/originador.
• Cisco Unified CME 7.1 ou superior.
An intercom line is a dedicated two-way audio path between two phones. Cisco Unified CME supports intercom functionality for one-way and press-to-answer voice connections using a dedicated pair of intercom directory numbers on two phones that speed-dial each other.
When an intercom speed dial button is pressed, a call is speed-dialed to the directory that is the other half of the dedicated pair. The called phone automatically answers the call in speakerphone mode with mute activated, providing a one-way voice path from the initiator to the recipient. A beep is sounded when the call is auto-answered to alert the recipient to the incoming call. To respond to the intercom call and open a two-way voice path, the recipient deactivates the mute function by pressing the Mute button or, on phones such as the Cisco Unified IP Phone 7910, lifting the handset.
In Cisco CME 3.2.1 and later versions, you can deactivate the speaker-mute function on intercom calls. For example, if phone user 1 makes an intercom call to phone user 2, both users hear each other on connection when no-mute is configured. The benefit is that people who receive intercom calls can be heard without them having to disable the mute function. The disadvantage is that nearby background sounds and conversations can be heard the moment a person receives an intercom call, regardless of whether they are ready to take a call or not.
To enable a two-way audio path between two phones, perform the following steps for each Cisco Unified SCCP IP phone at both ends of the two-way voice path.
Restrictions
• Intercom lines cannot be dual-line.
• If a directory number is configured for intercom operation, it can be associated with only one Cisco Unified IP phone.
• Each phone, at both ends of the two-way voice path, requires a separate configuration.

Whisper intercom significa que apenas um caminho de áudio (one-way) existe a partir do chamador para o interlocutor. O interlocutor deve pressionar manualmente a chave/botão para falar com o chamador. Quando um usuário disca whisper intercom, o telefone chamado responde automaticamente usando o modo viva-voz, fornecendo um caminho de voz do chamador para a parte chamada, independentemente da se o número chamado estiver ocupado ou pronto.
Unlike the standard intercom feature, this feature allows an intercom call to a busy extension. The calling party can only be heard by the recipient. The original caller on the receiving phone does not hear the whisper page. The phone receiving a whisper page displays the extension and name of the party initiating the whisper page and Cisco Unified CME plays a zipzip tone before the called party hears the caller's voice. If the called party wants to speak to the caller, the called party selects the intercom line button on their phone. The lamp for intercom buttons are colored amber to indicate one-way audio for whisper intercom and green to indicate two-way audio for standard intercom.
You must configure a whisper intercom directory number for each phone that requires the Whisper Intercom feature. A whisper intercom directory number can place calls only to another whisper intercom directory number. Calls between a whisper intercom directory number and a standard directory number or intercom directory number are rejected with a busy tone.
To enable the Whisper Intercom feature on a directory number, perform the following steps.
Restrictions
• Single-line phone models, such as the Cisco Unified IP Phone 7906 or 7911, are not supported.
• Whisper intercom directory numbers can place calls only to other whisper intercom numbers.
• A directory number can be configured as either a regular intercom or a whisper intercom, not both.
• Dual-line and octo-line directory numbers are not supported as intercom lines.
• Only one intercom call, either incoming or outgoing, is allowed on the phone at one time.
• Call features are not supported on intercom calls.

Button 2 on Harry's phone is an intercom line. This line is set to autodial Ana's phone using the number 1111. The button is labeled "Ana" to show that pressing the button intercoms to Ana. NOTE:- The intercom lines are configured in the default single-line mode. Ana's phone is configured to match to Harry's phone. Button 1 on Ana's phone is her primary line. Button 2 is set to autodial Harry's phone and shows the label "Harry" next to the button. The default configuration for an intercom line is that it autoanswers with mute for any incoming call. Autoanswer can be disabled if desired using the no-auto-answer command option.Harry can intercom to Ana, and Ana can intercom to Harry. Individual phones may have more than one intercom. The maximum number of intercoms per phone is limited only by the number of available buttons. In general, using intercoms on single-line phones such as the Cisco 7910, 7905, and 7912 is not recommended. These phones do not have a built-in (hands-free) microphone and, therefore, cannot be unmuted without lifting the phone's handset. |
This arrangement lets you create a many-to-one intercom, which is useful when you have a single shared assistant working for multiple executives.
Shared-Line Intercom
Intercom lines cannot be used in shared-line configurations. If a directory number is configured for intercom operation, it must be associated with one IP phone only. The intercom attribute causes an IP phone line to operate as an autodial line for outbound calls and as an autoanswer-with-mute line for inbound calls.

router#show running-config ephone-dn 1 dual-line number 2101 name Executive1 ! ! ephone-dn 2 dual-line number 2102 name Executive2 ! ! ephone-dn 3 dual-line number 2103 name Executive3 ! ! ephone-dn 4 dual-line number 2201 name Assistant ! ! ephone-dn 5 number 1110 intercom 1110 label Intercom ! ! ephone-dn 6 number 1111 intercom 1110 label Intercom ! ephone-dn 7 number 1112 intercom 1110 label Intercom ! ! ephone-dn 8 number 1113 intercom 1110 label Intercom ! ! ephone 12 mac-address 000d.1234.0efc button 1:1 2:6 ! ! ephone 13 mac-address 000d.5678.0dcf button 1:2 2:7 ! ! ephone 14 mac-address 000d.4321.0ef7 button 1:3 2:8 ! ! ephone 15 mac-address 000d.4132.f7e4 button 1:4 2:5 --------------------------------------------- ephones 12 to 14 belong to the three executives 2101 to 2103. The fourth phone, ephone 15, belongs to the assistant. Each of the four phones has its primary line associated with button 1. The second buttons on the three executive phones are configured to intercom to the assistant's intercom line. This configuration provides a many-to-one intercom. Any of the executives can press the button 2 intercom on his or her phone to talk to the assistant. Of course, only one intercom conversation can exist at one time. Note:- that the assistant's intercom (ephone-dn 5) is set to autodial itself. It is not possible to create a one-to-many intercom path. The assistant's phone could also be configured to autodial one of the executives. |
You can use this technique to configure a one-way intercom even in a simple one-to-one intercom arrangement. A better configuration for a one-way, one-to-one intercom is to use the noautoanswer command option.
| Sample Configuration |
|---|
router#show running-config ephone-dn 1 dual-line number 2101 name Executive ! ! ephone-dn 4 dual-line number 2201 name Assistant ! ! ephone-dn 5 number 1110 intercom 1111 label Intercom ! ! ephone-dn 6 number 1111 intercom 1110 label Intercom no-auto-answer ! ! ephone 12 mac-address 000d.1234.0efc button 1:1 2:6 ! ! ephone 15 mac-address 000d.4132.f7e4 button 1:4 2:5 With this arrangement, you still have a direct one-to-one dedicated line between the executive and the assistant. Only the assistant's phone autoanswers incoming calls presented to its intercom line. If the assistant presses the intercom line, the phone still autodials the executive's intercom line. The executive's phone simply rings as for a normal call. |
