Zusammenfassung:	According to various embodiments of the present invention, disclosed is an electronic device including a communication circuit, a processor and a memory. When executed, the memory stores instructions allowing the processor to: transmit, to a network, a first session initiation protocol (SIP) invite message including at least one dummy value by using the communication circuit; acquire channel state information by using the communication circuit; determine codec for conducting a packet-based call based on the channel state information; and transmit a second SIP invite message including the determined codec information to the network by using the communication circuit. Besides, various embodiments identified through the present specification are possible. Therefore, the electronic device can prevent deterioration of call quality due to the loss of packet. 다양한 실시예들은, 통신 회로, 프로세서, 및 메모리를 포함하는 전자 장치가 개시된다. 상기 메모리는 실행되었을 때 상기 프로세서로 하여금 상기 통신 회로를 이용하여 적어도 하나의 더미(dummy) 값을 포함하는 제1 SIP(session initiation protocol) 인바이트 메시지(invite message)를 네트워크에 송신하고, 상기 통신 회로를 이용하여 채널 상태 정보를 획득하고, 상기 채널 상태 정보에 기반하여 패킷 기반 호(packet based call)를 수행하기 위한 코덱(codec)을 판단하며, 상기 통신 회로를 이용하여 상기 판단된 코덱 정보를 포함하는 제2 SIP 인바이트 메시지를 상기 네트워크에 송신하게 하는 명령어들(instructions)을 저장할 수 있다. 이 외에도 명세서를 통해 파악되는 다양한 실시예가 가능하다.
