This is normally a config issue. I would like you to test the below.
a) Issue the below commands in the isdn interface
int se 1/0/0:23
no isdn out ie display
shut and no shut the interface and test the call again.
b) Compare the isdn switch type and confirm that the gateway configuration matches the other end.
