Hi everyone, I'm looking from advices on that issue : In the following scenario, where A & B are PSTN subscribers : STEP 1 : A call freeswitch, freeswitch answers and play an audio prompt. STEP 2 : when the prompt ends, freeswitch attempt to bridge A with B STEP 3 : B_answer. I set a no_local::execute_on_answer hook to park A and play B an audio prompt (warning message) when B_answer. But thuis is what happen when the bridge command is executed : CASE 1 : If the INVITE TO B is responded with a 183-SESSION_PROGRESS before the 200-OK, the execute_on_answer hook work as i expect (A is parked, B is played the audio prompt) CASE 2 : If the INVITE TO B is responded with a 200-OK, the execute_on_answer hook does not work as i expect (A is parked but hangup B with cause destination_out_of_order).

From the trace i can see that in CASE 1, B party is put in CS_EXCHANGE_MEDIA earlier than in CASE2

Would this be likely to create the problem ? Best Regards, Julien
