I am trying to access User-User Information received on an inbound PRI call.
Below is the debug ouput for the PRI packet.
< Protocol Discriminator: Q.931 (8) len=60
< Call Ref: len= 2 (reference 509/0x1FD) (Originator)
< Message type: SETUP (5)

< User-User Information (len=21) [ 32 30 30 37 30 37 30 39 31 34 33 31 31 30 30 31 30 32 37 ]
In the dial-plan, I would like to access the data in the User-User info - the 19 digits that are included in the 13th element.
Is there a way to do that?
