[Freeswitch-users] Skype message event miss match in concurrent call

Hi, I am using skypopne with 2 account A and B. And A is the callee to receive call. During the call skype chat message is used as a method of input. According to skypopen logic, when C call A first and then D call A. B will pick up the call from D. On some mobile version skype, the transfer from A to B is not reported to mobile user. So user D will still send message to A. In my event processing script(in js). The session C->A will receive all message D sent to A while D to B session receive nothing. Hence caller D will not be responsed by system. Is there any way to handler this situation? For example, when C->A session receive a message from D, can I fire it again into D to B session?
