Hi, I have Freeswitch and other two SIP sets all registered with a SIP proxy/registry, and I am writing a control software to control the freeswitch via event socket. Baisically the control software tells freeswitch when someone calls it, what action to take, for example, acts as Auto attendant and play prompt. Etc. Now I got a problem when A calls B then attended transfer B to freeswitch, The prompt B hear is not from the beginning, it actually hears the trailing part of the prompt played to A when A called freeswitch in the beginning of the transfer. I understand that's because nobody tell freeswitch to stop and start from the beginning. I am looking for what event should the control software monitor for the replaced session (the transfer is done via "invite replaces" ) and how to cancel the current prompt and start from beginning. Any suggestions are greatly appreciated. Thanks Xingjun
