"Unknown Number" upon connection

I have a QSIG ISDN-30 to a service provider. When making an outbound call, whilst the number is ringing, my phone shows the dialed number. But once the call connects, the phone display changes to "Unknown Number". Below is a "debug isdn q931" for such a call. Any suggestions as to how to have/keep the dialed or connected up displayed on the phone ? I think it's because of something the service provider is sending back to me, but I can't decode the "Facility" messages :-(

"Unknown Number" upon connection

When the call is connected the remote party sends you "Unknown Number" in the CONNECTED NUMBER header:

Nov 27 10:31:57: ISDN Se0/0/0:15 Q931: RX <- CONNECT pd = 8  callref = 0x8006

    Channel ID i = 0xA9839F

        Exclusive, Channel 31

    Connected Number i = 0x01C3

This service is called Connected-Line Identification Presentation (COLP).
