DDI

Otherwise known as a telephone number, this is how other people will be able to contact you on your new Byphone system. By default, we give you a new number to allow you to start receiving calls on your phone system as soon as possible. You can also contact us about porting an existing number you own onto the system. DDIs are usually related to either a main business function i.e. department for larger organisations or simply the main number that all company calls come in through or a User's direct dial, so that they can be contacted directly, without having to go through anyone else in the company to get there, which is much more convenient.

A DDI is then only useful when used in conjunction with other applications to allow you to answer your calls. These applications could be Ring Groups when looking at the business as a whole, or Follow Me when looking specifically at a user. There may be some other business logic in between before getting there, but as it's the foundation, this is how calls get answered.

Therefore a DDI must route to some other application. In Byphone, this is done on the call flow.

First, go to the Call Flow tab.
You should now see the Call Flow window and any DDIs will be shown inside a green node.
Click on the Edit button to manage your Call Flow.
You can add other applications here. (Please see their respective pages for more information about them)
To connect your DDI to an application, simply click on it to see it's options.
Click on the symbol, and drag the symbol (for success route) from the DDI to your desired application to link the two together.
A DDI can only ever point to one place, you can fork it using other applications such as Time Conditions, which will route differently based on the time of day, a Day/Night Toggle, which is a manual toggle to enter Day or Night mode and route accordingly, or IVR to allow a keypad number press to route the call.
You can also label your DDIs according to what they are used for, by clicking the DDI node and then selecting the Edit option.
Don't forget to Save the changes you make to the Call Flow, or they will be lost and you may have to start again.

User Direct Dial

That covers a DDI connection on your main Call Flow, but what about your Users? This is done using on the same page in a different view, but functionally is the same.

On the Call Flow beside the Edit button click on the Follow Me View button
This will allow you to toggle between editing Follow Me flows or the main company flows
Again, Click Edit while in the Follow Me View.
Any DDIs that are already pointed to a Follow Me will be shown here, as well as any other DDIs that are not yet in use
Connecting a DDI to a Follow Me is done in exactly the same way
Click on the desired DDI
Select the symbol
Drag the symbol from the DDI to the Follow Me you would like it to point to
Save your changes and that's it

Provided your Follow Me, or whatever other application you have pointed your number to, has already been set up, you should now be able to test a call and have it hit whichever application or devices you chose.

There are a limited set of settings that can be changed on your DDIs. See below:

Setting	Possible Values	Description
Number Prefix	Up to 20 alphanumeric characters	This setting is displayed on inbound calls to your registered devices before the caller's telephone number. This is useful where Users may answer calls for multiple different companies and need to know which company the caller is expecting when they answer.
Main Number	On/Off	This can be toggled on or off for a DDI. Only one DDI on your Byphone system can be considered a “Main Number”, when toggled on for one number, any other Main Number is automatically toggled off. This Main Number is used as the Outbound CallerID for any user who has not already specifically set one, or as the Outbound CallerID for emergency services where a User may have their CallerID set to Anonymous. See Outbound Number Presentation for more info.
Record Calls	Yes/No/Don't Care	This allows you to enable Call Recording for calls received on a particular DDI. This may be helpful when you want to record all calls to your support number, but not record calls to a whistleblower hotline, for example, for confidentiality.
Music On Hold	Dropdown	This setting allows you to associate a series of audio files to be played to the caller of this number when one of your users places them on hold. Most commonly used for marketing messages. Classes can be added to this dropdown by adding to the Music on Hold section under the configuration tab.
