ISDN issue

Hi,

I encountered problem in bringing up my isdn line. When I run debug q931 and debug isdn error the following output is shown. May I know what could be the cause? My ISP had checked the line and is fine. They are able to call out using their isdn phone.

Debug isdn q931 output

*Oct 12 14:14:54 MAL: ISDN BR0/2/0 Q931: RX <- CALL_PROC pd = 8 callref = 0xF1

Channel ID i = 0x89

*Oct 12 14:14:54 MAL: ISDN BR0/2/0 Q931: RX <- DISCONNECT pd = 8 callref = 0xF1

Cause i = 0x02809B - Destination out of order
