Dial Codes

Dial codes are particular key/number combinations used to access functions within the phone system directly from the phone.

Call Pick-up

If you hear a particular extension ringing, and you know that person is not able to take the call, you can take the call using the ‘Call Pickup’ feature. To do this, type:

*20* <extension number>

This will redirect the active call from the specified extension to your extension. You can also retrieve a call from a ringing extension without specifying the extension number. To do this, type *20* followed by the send key. This will redirect the first available active call to your extension.

Call Parking

If you wish to “park” a call and then pick up the call from another extension, then you can park the call in a ‘Parking orbit’ and then pick up the call from another extension.

To park a call:

BLIND TRANSFER BUTTON followed by *00 to 09 to specify the parking orbit.

For example *01 will place the call in the parking orbit 1.

To pick up a call:

*10 to 19 where the 0 – 9 is the park orbit number

For example *11 will pick up any calls parked in parking orbit 1

Multiple calls in Parking Lots

Parking lots support parking of multiple calls. Therefore, when un-parking, you can add the extension number from which the call was parked to be sure that you un-park the particular call you had parked there.

For example, if extension 100 parked a call in park 0, this call can be picked up by extension 101 by keying in *10100

Examples for Popular IP Phones

Some examples to park a call with popular phones:

  • Grandstream -press the TRNF button and dial *00
  • Snom – press the TRANSFER button and dial *00
  • Polycom – press the TRANSFER button, from the screen, then choose the option BLIND and then dial *00
  • Cisco – choose “more” option on the screen, choose BlndXfr and dial *00
  • Linksys – press the right arrow key on the navigation button for more options and then choose bxfer and dial *00

Note: Call Pickup and Call Park are only available in commercial editions of 3CX Phone System

Voicemail

To leave a message in a Voicemail box of a particular Extension:

Dial *4{ext}

For example, *4100, will leave a voicemail message in the voicemail box of extension 100.

Setting Do not Disturb ON / OFF

To specify DND (Do Not Disturb) for a particular extension:

  • Dial *60 to set the extension to Do Not Disturb OFF.
  • Dial *61 to set the extension to Do Not Disturb ON – A busy tone will be sent.

Logging in to the Queues

To log into a queue;

  • Dial *62 to log the extension into all the Queues that the extension is a member of.
  • Dial *63 to log the extensions out of all the queues to which the extension has logged in.

Note: Queues are only available in commercial editions of 3CX Phone System

Intercom

The intercom feature allows you make an announcement to another extension without requiring the other party to pick up the handset. The message will be played via the phone’s speaker. The audio is two way, and the called party can respond immediately without picking up the handset. To call a user via the intercom function:

Prefix the extension you wish to call with *9, followed by the extension. For example to make an intercom call to extension 100 you should dial:

*9100

Note: The intercom features require a phone that supports intercom and that is configured to allow it. Check with your administrator if in doubt.

Billing Code

The Billing Code feature default value is **, allows you to add a tag to a call you want to make. For example we will inform a sales person that he has to append a billing code of “salesproject” to every call  he/she makes related to “salesproject”.  The sales person will dial a call in the following format – Destination**salesproject. Example – if the sales person wants to call his colleague on number 96626870 related on a salesproject affair, the dialed number will be as follows -96626870**salesproject.

This billing code can be later on filtered in the 3CX Call Reporter to see how many calls were related to this project called “salesproject” by doing the following query.

Billing Code Query with 3CX MyPhone

Here we see that a % sign (that represents the wildcard anything in SQL) is set followed by ** which is the billing code and “salesproject” which is the billing code tab.

This will query and display all the calls that were made using the salesproject billing code tag.

Code to Control IN/OUT Office Status of PBX – Emergency Code

This dial code (which is unspecified by default for security purposes) is a code that when used, will set the whole 3CX Phone System to either a) In office hours, b) Out of Office hours or c) will instruct the 3CX Phone System to fall back to the configured global office hours at that particular day and time. This code is designed for emergency services when you need to change the routes of all your VoIP Lines to IN or Out of office quickly with a single phone call.

Usage of this Dial Code

Let us assume that the administrator configures this dial code to be *64.
Let us also assume that the global office hours are set from 9am till 5.30pm.

Setting all your Ports to In Office Hours

If the Administrator dials *641 (appends a 1 to the code), a prompt will be played stating that the “3CX Phone System is now set to IN OFFICE HOURS”. This means that the 3CX Phone System will disregard the current time, or day (even if it is a holiday) and set all the routes of the Gateways, VoIP Providers and DID/DDI’s to route to the In Office hours destination.

Setting all your Ports to Out of Office Hours

If the Administrator dials *642 (appends a 2 to the code), a prompt will be played stating that the “3CX Phone System is now set to OUT OF OFFICE HOURS”. This means that the 3CX Phone System will disregard the current time, or day (even if it is 10am for example) and set all the routes of PSTN Gateways, VoIP Providers and DID/DDI’s to route to the Out of Office hours destination.

Setting all your Ports to Default Office Hours Operation

If the Administrator dials *64 (with nothing appended), a prompt will be played stating that the “3CX Phone System is now using the DEFAULT OFFICE HOURS”. This means that in this example, the 3CX Phone System will override the previous 2 commands and behave as follows – from 9am till 5.30pm lines/ports will be routed to In Office Hours destinations and from 5.31pm till 8.59am, the lines/ports will be routed to the Out of Office hour destinations.
