Hi everyone. I have a TDA 50 that I am trying to put a Sound Station on. I cannot seem to get my XDP port to work. I can get an intercom tone to call another station but that station cannot display the extension that I am calling from. Also I cannot dial 9 to get an outside line. I thought that the XDP port would be 204 in this case, but I cannot intercom 204. And as I stated if I intercom another station it does not display where I am calling from. Any ideas what could be going on? In port property I have XDP turned on.
