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<12345@sip.com;user=phone>. Does anyone know why this happens?

Thanks in advance
