Abstract: The disclosure relates to a method and apparatus for determining an internal user for a call center system. The information servicing function provided in the existing communication networks may be utilized in the invention. After a call initiated from an internal user for a call center system to an external user fails, the call center system sends the call information to the external user in a timely manner so that the external user can obtain identification information of the internal user for the call center system in a timely and accurate manner. With the invention, the possibility of reaching the internal user for the call center system is enhanced and thus the interests of the external user and the enterprise entity can be secured.
