DIDs

DIDs are 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.

The same DID cannot be assigned more than once.

A DID can be configured to accept voice, fax or try to guess the calling party (if voice of fax).
Autodetection relies on signaling at the start of the call and cannot be always reliable.

Editing New/Define DIDs

The number must be entered in three parts, starting with international prefix, area code and number.

Comment is just a comment and it is not used in any way.
Max channels allows you to set the maximal number of channels available on the DID. Any additional call received will be refused with a busy signal..
Use as Emergency CallerID permits you to mark this DID as one of the available to be used when an emergency call is dialed. These must be registered with the e911 Database (call NETRIO if you have questions).
