Hi Kevin,
In the following FAC Message, you have to fetch the calling name.
Oct 15 16:32:27.231: gtd msg = "FAC,
PRN,isdn*,,NI***,
GEN,y,y,0,JOE BLOW ----------------Caller NAME
Here the GTD message is FAC : gtd_fac
The NSS parameter is :gen
And the sub parameter is :name
So you can get the calling name in this order,
If you still have any issues you can open a case for this
If you do not have developer support contract here is the link for the information.
