Hello, here's the description of my problem. On PGW 9.5.2 there is incoming ISDN and outgoing SIP trunks. In ISDN setup message there is a name of subscriber A transmitted (in DISPLAY parameter(e.g. DISPLAY John, Calling number 12345)). In the output sip INVITE message instead of name there is a A's number. e.g. the from field is like this
12345<firstname.lastname@example.org;user=phone>. Does anyone know why this happens?
Thanks in advance
