Abstract: An electronic device connected to a first communication network is provided. The electronic device may include: a communication module comprising communication circuitry; a processor operatively connected to the communication module; and a memory operatively connected to the processor, wherein the memory may store instructions that, when executed, cause the processor to control the electronic device to: transmit a message requesting a call connection through a first transmission protocol to an external electronic device using the communication module; receive a provisional response message for the request through the first transmission protocol from the external electronic device using the communication module; connect to a second communication network using the communication module based on the call connection not being supported by the first communication network; transmit a response message for the received provisional response message through a second transmission protocol to the external electronic device using the communication module; and perform the call connection using the connected second communication network.

Abstract: An electronic device includes at least one display, a communication circuit, at least one processor, and a memory. The processor is configured to obtain information on a first display aspect ratio associated with a current state of the at least one display if an input indicating initiation of a video call is received. The processor is configured to determine at least one first image ratio associated with the video call based on the information on the first display aspect ratio. The processor is configured to transmit, to an external electronic device, a first signal including information on the at least one first image ratio. The processor is configured to receive, from the external electronic device, a second signal including information on a second image ratio associated with the video call. The processor is configured to perform the video call based on the second image ratio.
