Electronic device for determining call type with external electronic device and method thereof

An electronic device comprising:

• communication circuitry;
• memory, comprising one or more storage media, storing instructions;
• and
• at least one processor communicatively coupled to the communication circuitry and the memory,
• wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
• configure a call setup with an external electronic device via the communication circuitry,
• control the communication circuitry to transmit at least one request message based on a first protocol,
• receive at least one response message corresponding to the at least one request message via the communication circuitry,
• identify a first response time, based on a transmission time of the at least one request message and a reception time of the at least one response message,
• control the communication circuitry to transmit a howling generation sound-source,
• receive a howling response corresponding to the howling generation sound via the communication circuitry,
• identify a second response time, based on a transmission time of the howling generation sound and a reception time of the howling response, and
• determine whether a call between the electronic device and the external electronic device is a normal call, based on the first response time and the second response time.
