Since several days you ask questions about how to call out, now you say you have a trunk sip but you don't know what to set , Your provider, if you have really one, gave you all informations about what to set and the SIP number included, if you have nothing, you are kidding us with your pseudo newbie questions.
all screen copy you have done are empty shell , nothing is set
Seems to me you turn around to find something to call free and nothing else.
