[cisco-voip] Modify Screening Indicator

[James.Brown at barclayswealth.com]

Does anyone know whether it's possible to change the screening indicator on outbound Q931 calls with MGCP please?

ISDN Se0/1/0:15 Q931: TX -> SETUP pd = 8  callref = 0x01A1
        Sending Complete
        Bearer Capability i = 0x8090A3
                Standard = CCITT
                Transfer Capability = Speech
                Transfer Mode = Circuit
                Transfer Rate = 64 kbit/s
        Channel ID i = 0xA9839C
                Exclusive, Channel 28
        Calling Party Number i = 0x50A3, '1234567'
                Plan:Unknown, Type:Unknown
        Called Party Number i = 0x80, '0044123123123'
                Plan:Unknown, Type:Unknown

In the trace above, the Calling Party Hex (0x50A3) tells me the presentation indicators are "01" (Restricted) and the screening indicators are "11" (Network Provided). Unfortunately, our carrier interprets this as though we wanted to display our main number.

The only settings I can see within the CUCM gateway and route pattern pages appear to relate to the presentation indicator.

Any suggestions would be greatly appreciated.

Kind regards

James.
