Incoming call issue for accepting

[bidawaptg2023]

I am facing issues when accepting new incoming calls. I received a VoIP push from the server. When I receive a VoIP push notification then loged in to the linphone after that make a reset API call to the server to resume incoming call and send an invite to the iPhone user. but before the API process completion the user accepts the incoming call through the call kit and a new call invite is received after the incoming call is accepted by the user then incoming call will never accepted by the user but call kit shows call is started. How can I fix it in linphone IOS. On server side we are using the Kamailio server.
