Call Accounting Terms Defined


FAQ Index: Glossary of Terms

  • Analog Line / Trunk 
    An Analog Line is a plain copper line, also referred to as a POTS Line like the one that provides phone service at your Grandma's house.
  • Authorization Code
  • Caller ID - Inbound Calling Number  
    Caller ID show the phone number of the incoming caller.  
  • DID - Direct Inward Dial
    A DID extension has an extension and an outside 10 digit number.  That number is assigned in the phone system so that when a call comes in on that number it uses DNIS to automatically route that call to the DID extension.  This basically makes the phone number a private phone number for that extension.
  • Digital Trunk  A digital trunk is a type of telephone line that carries digital phone, data, or network traffic.  Digital trunks have many more features available than analog trunks and can move data much quicker and can handle much larger traffic loads than analog trunks.
  • DNIS / Direct Number Identification Service  DNIS is the incoming number that a customer dials to reach your office.  Phone systems use this incoming number information to route a phone call once it hits your office. It is used to route DID Numbers, route calls to departments like sales or support, and to be able to route Toll Free Numbers to a specific department.
  • Dropped Call
    Depending up on your telephone system a dropped call can mean different things.  Depending on the model of your phone system a dropped call may or may not be tagged in your phone system call data.  Here are some examples of what most phone systems consider a dropped call:    
  • An outside caller hangs up while the phone is ringing
  • An outside caller hangs up during a greeting announcement
  • An outside caller hangs up while waiting on hold
  • An outside caller hangs up while a call is being transferred.
  • Or for some reason if the call is dropped by the phone system during the call.
  • DTMF
  • Hold Time
    The length of time that a call was placed on hold during the current call
  • IP Address / Port # 
    Used to connect computers and servers to a network and to the Internet

  • Park Time
    The length of time that a call was parked during the current call.  This is similar to hold, except that there is usually a parked code assigned to the call.  If the operator answers a call and parks it on 128, she can page overhead and tell you that you have a call on 128.  You can then to to any telephone and pick up the call with that code, as opposed to having to go back to your extension and wait for the operator to transfer the call to you.
  • Ring Time
    The amount of time that the active call rings before you answer it.  With most phone systems the ring time starts when the call hits the phone system (before it is answered).  On most phone systems, outbound calls start timing a call the moment you pick up the handset.
  • Serial Settings - Baud/Parity/Start & Stop Bits
    Used to connect computers and servers to a network and to the Internet
    See More
  • SMDR / CDR
    Station Message Detail Recording / Call Detail Recording.  Both terms mean the same thing as Call Accounting.  See More
