Could someone explain what exactly the Trunk setting 'update caller id' is doing ?
My trunk settings :
HeaderRequestUri: {request-uri}
HeaderFrom: {trunk}
HeaderTo: {request-uri}
HeaderPai:
HeaderPpi:
HeaderRpi: "{trunk-display}" <sip:{trunk-ani}@{domain}>
HeaderPrivacy:
I have a Voip Provider where Remote-Party-Id is responsible for the Number/Call identification.
I would like the behaviour that an incoming call, that is send though the pbx to another line, displays its original number to the other end. Right now it is the Trunk Ani that displays on the receivers phone.
Can anyone give me a hint how to do this ?
Thanks,
Marc
