Using SIP trunks I would like to have the original caller id be sent to ANY and ALL phones that the call is sent to. if the call gets answered and transferred to a phone then I want that Info there, if the call gets sent to another phone I want that info going to that phone. I do not care if the internal info gets sent. I have tried various combinations of trustrpid and sendrpid with little luck What other options is there?
Depends on your phone. Some phones just don’t support it.
I just found that out on our phones. The Manufacturer is adding to our firmware.
