I have run into a subject that I need some clarification on. I have always been advised that Caller ID info, such as calling number, cannot be transmitted through an MF Trunk. Someone has now stated that LRNs have to be sent through MF trunks ... and depending on how those trunks are set up as to whether the calling party number will display on the receiving end. Does anyone have a deep knowledge of how the MF trunks function and if the calling party number can actually be broadcast to the receiving phone? Your assistance will be deeply appreciated!!!
