Product Listing
Last Call Return -- V9.0
Product Description
Last Call Return allows the end-user to hear the telephone number of the last incoming call by dialing an access code, whether the call was answered or not.
- Allows the end-user to "prompt" the central office to redial the telephone number of the last incoming call by dialing 1.
- Provides the telephone number of the last incoming call before the prompt to return the call.
If, after dialing 1 to have the central office connect the end-user with the last incoming caller, the end-user reaches a busy signal, the Last Call Return service will automatically continue to redial the number for up to 30 minutes.
When the Last Call Return service determines that the last incoming telephone number is no longer busy, the central office will ring the line with a distinctive ring (short, short, long) to let the end-user know the call can now be completed.
After receiving the distinctive ring, the end-user can:
- Ignore the distinctive ring. The central office will attempt to reestablish the call later.
- Pick up receiver. The central office will instantly place the call. If the end-user should reach another
busy signal:
- In a DMS™-10, DMS-100 or Ericsson central office (CO) switch type, hang up and Last Call Return will automatically be reactivated.
- In all other switch types, the end-user will receive an announcement advising to reactivate Last Call Return by dialing *69 or 1169. Activation and deactivation code information is applicable for POTS and Centrex 21 products. Centrex Plus, Centrex Prime®, and Centron® products access code information can be obtained from your CenturyLink Sales Executive for new accounts or CenturyLink Service Manager for existing accounts.
If the call could not be completed and the Last Call Return end-user is waiting for the central office to complete the call, "ring back" will not occur unless both lines are idle.
To reactivate Last Call Return when contact has not been established within the 30-minute time limit: Go off hook and listen for a dial tone and then dial *69 or 1169 or the designated access code.
- NOTE: The end-user must reactivate the Last Call Return feature prior to making any new calls. If they make a new call before reactivating the feature, it will redial the most recent call.
If during the 30 minute period, the end-user chooses to cancel the service, they can deactivate Last Call Return by dialing an access code.
Both ends of the call, the incoming number and the called number, must be in a Custom Local Area Signaling Services (CLASSÒ) equipped CO for Last Call Return to work.
When Last Call Return is activated and a long distance number is heard, the call cannot be called back by dialing 1.
Last Call Return will not return a call if the incoming caller marked their telephone number private.
End-users can prevent access to Last Call Return by having their access lines blocked.
Telephone numbers, from incoming calls which were blocked, are not given out with Last Call Return; however Last Call Return will allow an end-user to dial 1 to have the central office dial the telephone number back for you.
Last Call Return is available in most areas. Not all calls will be identified, and some calls may be identified but may not be able to be returned. Charges apply if the call is identified. In selected states, blocked calls cannot be returned. Some restrictions apply. Measured service and long distance charges may apply for completed calls. Instant Service Last Call Return (Pay Per Use) may not be available in some areas of Oregon and Washington.
