I need to call from an extension A registered in my freeswitch another extension registered in my soft phone B 

i have done this : originate {origination_caller_id_number=A,origination_caller_id_name=A}user/B A 

is this correct ? 

also I want to have anonymous  call so i replace origination_caller_id_number and origination_caller_id_name with anonymous is this correct ? 

last question I need to add P-Asserted-Identity do you know how please ? 

thanks,best regards
