Usage minutes begin at the moment the call is answered.  This answer from a technical perspective is a SIP 200 OK.  A simple SIP call flow that determins a 200 OK is shown in the diagram below:

To summarize the above scenario:

• Usage billing starts when the call is answered (200 OK).

• 8x8 rounds to the highest minute.  If a call is a length of 1 second, a standard rounding to 1 minute will be billed.

• Noting: Billing usage begins when the called number answers, this may be any application or person that answers and a 200 OK is sent.

• See Claim Phone Numbers in 8x8 Admin Console.

• After the number has been claimed in Admin Console, create a case with 8x8 Technical Support who can then assign it to your X Series SIP Trunk.

• Should you later wish to use an X Series SIP Trunk number for another X Series service, simply contact 8x8 Technical Support who can then return your number to the Admin Console - Phone numbers list as an Available number.
