An electronic device comprising:

• a speaker;
• a touchscreen display;
• a communication circuit;
• at least one processor operatively connected to the speaker, the display, and the communication circuit;
• and
• a memory operatively connected to the at least one processor and storing instructions that, when executed by the at least one processor, cause the processor to:
• execute a calling application;
• attempt to connect a call to a service provider using the communication circuit;
• during call connection to the service provider, receive a first user input requesting a standby mode for connection to an attendant of the service provider, wherein the calling application is executed in a background in the standby mode;
• in response to the first user input, execute the calling application in the standby mode;
• while the calling application is being executed in the standby mode, determine whether the attendant is connected based on a voice transmitted by the service provider;
• in response to completion of connection to the attendant, output a notification indicating that the connection to the attendant has been completed using the speaker or the touchscreen display;
• and
• in response to reception of a second user input for the output notification, terminate the standby mode.

An electronic device comprising:

• a communication circuit;
• at least one processor operatively connected to the communication circuit;
• and
• a memory operatively connected to the at least one processor and storing instructions that, when executed by the at least one processor, cause the processor to:
• control the communication circuit to receive a request for a call connection to a service provider from an external electronic device, wherein the request comprises user information of the external electronic device and at least one piece of keyword information related to a detailed service and the service provider;
• in response to receiving the request, acquire an identification number for the call connection to the service provider;
• select a first menu corresponding to the detailed service included in the request from menu information comprising one or more detailed services provided by the service provider;
• control the communication circuit to attempt to connect a call between the service provider and the external electronic device;
• based on the call to the service provider being connected, control the communication circuit to transmit one or more responses until reaching a step corresponding to the first menu in response to one or more voice prompts provided by the service provider;
• in response to reaching the first menu, determine whether an attendant is connected based on at least one voice transmitted by the service provider;
• in response to completion of connection to the attendant, provide the external electronic device with information indicating that the connection to the attendant of the service provider has been completed using the communication circuit;
