DA Call Branding
“Call Branding” means announcing CenturyLink’s name, a generic name, or a customized name on the front end and/or back end of the Directory Assistance calls. You have the option of choosing what type of branding announcement you wish to have recorded and played at the beginning and/or end of your end-user’s calls to CenturyLink DA.
Front End Call Branding options announce CenturyLink’s name, a Generic Call Branding, or a Customized Call Branding at the beginning of the call.
Back End Call Branding options announce CenturyLink’s name, a Generic Call Branding, or a Customized Call Branding at the conclusion at the conclusion of the call.
Five types of DA Call Branding are available where technically feasible. Calls may be branded with CenturyLink’s Name, Generic Call Branding, or Customized Call Branding as follows:
- CenturyLink Name Branding – announces CenturyLink’s name
- Generic Call Branding – announces no name (e.g., Directory Assistance at front end
- Generic Call Branding – announces no name (e.g., ‘Local and National Directory Assistance’, which is only available on front end
- Generic Call Branding - announces ‘Your Local Telephone Company’ which is only available on the back end
- Customized Call Branding – announces your name (e.g., ABC Telephone Company – Directory Assistance (front end) and Thank you for using ABC Telephone Company (back end))
DACC Service
DACC service allows your end-users to connect to the requested local or intraLATA telephone number directly, using the QC intraLATA toll network, without having to dial another number. This is only offered with local and intraLATA telephone numbers and not with NDA numbers.
Reverse DA Service
Reverse DA service allows your end-users to obtain the name and address related to a listed telephone number. Depending upon the type of telephone number listing, your end-users may not be able to obtain the name and address due to restrictions, e.g., toll-free, non-publish, some cell/mobile listings, pagers, coin phones, second lines, etc. For non-listed telephone numbers, the address is restricted and only the name will be provided.
DA Search by Business Type
DA search by business type allows your end-users to obtain the name of a business(s) within a given locality by requesting a specific business type/category/classification, e.g., your end-user may access DA and request the name of a Dry Cleaner in the Denver area. Listings for the type of business requested will be randomly selected within the locality requested.
