Hello, I have done a small change in my dialplan which works but since I am new with FreeSWITCH I was wondering if this solution goes with the philosophy of the software or if it is absurd and there is a solution more adapted . I try to reproduce the following functionality: "A and B are on a simple call and decide to add C and have a conference. Later on they decide also to invite D..." In the dialplan I have added (based on the default dialplan): <extension name="Local_Extension"> <condition field="destination_number" expression="^(10[01][0-9])$"> ................ <anti-action application="bind_meta_app" data="1 a o transfer:: transf_call_${caller_id_number}"/> <anti-action application="bind_meta_app" data="2 a s transfer::-both transf_call_${caller_id_number}"/> ....... </condition> </extension> <extension name="transf_call_to_conf"> <condition field="destination_number" expression="^transf_call_(.*)$"> <action application="answer"/> <action application="conference" data="conf$1@conf_dynamic"/> </condition> </extension> Here, if A calls B then A can bridge both legs into a conference named "confnumberofA" by dialing *2. Then, A can put this call on hold and call C. - If C answers and agrees then A can press *1 in order to bridge C into the same conference "confnumberofA". A will come back into the conference which is still on hold. - If C does not answer then A will still be able to come back into the conference it puts on hold. My main problem is the name of the conference. Since everybody should be able to convert a simple call into a conference, the conference's name has to be unique each time. I have chosen to make it dependent on the caller number which is not perfect because then he is the only one which can bridge the call and add member. However, I do not have any other idea, maybe I have missed another possibility. I would be glad to get any critics you have, it would help me to better understand the fundamental concepts.
