Please post your config
According to this debug, the ADTRAN is receiving the SETUP message with no CALLED PARTY #. This is coming to the ADTRAN on the PRI - it is a received message.
The "Numb. Type:" and "Numb. Plan:" being "UNKNOWN" is not a problem. It's the " Ph.#" being empty that's the problem.
There isn't a configuration option in the ADTRAN to provide the CALLED PARTY # on a received ISDN call.
Hope this helps,
