DIDs

To every tenant can be assigned a group of DIDs, numbers to be dialed from the outside. 
Each DID can be configured to reach a certain extension or Queue or Hunt Group or IVR or any combination of the elements defined for the tenant.

 Editing DIDs

The number must be entered in three parts, starting with international prefix, area code and number. Even if your telephone standard doesn't allow the usage of any “short” form for dialing the number, requesting for example, to dial always the area code, the number is requested to be entered this way.

Please refer below details for the option used in DID,

Voice

This section allows to define how to route the call when a voice call is received.

Unconditional Forward is a destination that can be set on the DID to send the call to a particular destination. It is enable/disabled by the checkbox and that checkbox can be easily controlled by a feature code. This is not the destination to be set for common usage, you need to use the one in the Voice section.

Always record permits to force the recording of the call, whichever is the future of the call. Recordings will be available through the Call History menu.

Minimum Size (Bytes) allows to receive those recordings bigger than the size set, in Bytes. Recording takes place only on bridged channels, so IVR prompts or Music On Hold will be not recorded.

Using the Prefix CallerID Num is possible to define a string to be added to any CallerID number received to identify for example the DID the call is coming from. The same result can be achieved by defining a Custom Destination.
Prefix CallerID Name is the same as above, but for the Caller ID Name.
Destination multiple drop down allow to define the list and the order of the objects receiving the call.

You can select custom destination you have created like Mobile number, Huntlist or Queue or condition or directly the extensions number by selecting from drop down list.

You can assign the priority by dragging up and down the added item.
