System Setup Guide
Getting started with MyOffice PBX business phone system. (This won't take long!)

#2 Creating Your First Extension 

In this example, we will be creating our first user extensions.  There are two methods of creating extensions. You can create them one-by-one, or if you have several extensions to create, you can create extensions in blocks.  In addition to this tutorial, we have a how to create extensions in MyOffice PBX video.


1.  Begin by logging into MyOffice PBX. From the user dashboard, click “Accounts” on the main menu bar, then select “Extensions”.  



2.  From here you will see a list of your existing extensions. If this is the first time setting up your PBX, you should see that we have created the first 5 extensions for you. To begin, click the Add button located to the right of your screen.


Next  we will begin filling out our extension information. For this example, we will only cover the 5 fields needed to create a working extension. All other fields displayed will be left as-is.    MyOffice PBX support between 2 and 7 digit extensions. For our example, we'll be using a 4 digit extension. We will be setting up extension 1005.  

3.  So, in the Extension field, enter 1005 and in the Voicemail Password field, create the user a numerical password (in our example we used "44444").

4.  Next, we'll set the Effective caller ID name.  In this example, we will use the name "Evan Michaels" and the Effective caller ID number will be "1005". This information will be displayed to other internal PBX users.

5.  The next fields that we will address are the Outbound Caller ID Name. Again, we will enter "Evan Michaels", and the Outbound Caller ID Number, again for our example, we will enter the extension "1005".








6.  Next, check that the Enabled field is set to true (scroll down to the bottom of the page) – which it should be since this is a new extension.




7.  From here, we'll just click “Save” and our new extension number 1005 has been created and should be displayed in our extensions list



8.  The last step is to retrieve your newly create extension's password, which will have been automatically created. To locate your SIP username and SIP password, just click on the “Edit” button, on the right, you'll see that there's an additional field now showing. This is your “Password” field. If you click on this field, the asterisks will clear, and you will see that your extension's SIP password is displayed. Your SIP username is simply your extension number. (in our case 1005).





You've now created a new extension (#1005).  Next, you will need to register a phone to this extension in order to begin placing and receiving calls.



Creating Blocks of Extensions (BULK)

Additionally, we can create extensions in blocks. So if you have a large number of extensions that you would like to setup, you can do them all at once with just one change.


  1. To do this, just go back to the extensions page (Accounts -> Extensions) from the main menu.
  2. To create a total of 10 additional extensions... say 1006-1015. We can, simply click the “plus” button, and go to the extensions creation page.
  3. From here, we'll enter extension 1006 in the Extensions field.
  4. Next, we'll want to set the range (or quantity of extensions) to be a total of 10. So we'll use the drop-down and select "10" as our block quantity.





5. We'll then scroll down and ensure that “True” is again enabled.




6. And finish by clicking “Save”


7. Now if you go back to the the extensions page (Accounts -> Extensions), you'll see that you've now created 10 additional extensions, numbered 1006 through 1015 and they're all showing that they are enabled.





8. From this point you can edit each extension individually, by clicking the edit button next to each extension and customize each user.




Here are a list of fields and their function:

  • Extenson: This is the extension number or name if used with Number Alias
  • Number Alias: Number extension if extension is a name
