Hi, 101 Calls on 102 then 102 Do a att_xfer by pressing 1 while conversation on which bind_digit_action executes the att_xfer to 103 if 103 Answers the Call 101 Gets the Hold Message and 102 Start getting sound of 103 But, 103 is unable to hear the sound of 102 who done the att_xfer and if 102 Disconnects the Call then 103 is Bridged with 101 properly and both users can talk and hear each other. So, the problem is 103 is unable to hear 102 and there are no sip problems etc.. as we are using PRI/ISDN Lines and have also tried with sip both have same issue. See my Dial Plan. <extension name="Main IVR"> <condition break="on-false" expression="^101" field="destination_number"> <action application="answer"/> <action application="bridge" data="{execute_on_answer='bind_digit_action bridge_1,1,exec:att_xfer,freetdm/1/a/103'}[leg_timeout=60,origination_caller_id_number=123456]freetdm/1/a/102"/> <action application="hangup"/> </condition> </extension> -- ------------------------------------------------ Thanks & Regards Nitin
