I have a CME installation. They want the FNA destination to be an external number. When you dial the DN and let it FNA from an internal phone the external forward works fine. When you call in from external and the call forwards back out it does not work. From the q931 debugs the CME sends the forwarding DN's number to the PSTN and not the FNA destination.
The Q931 is of the failed call forward. The first setup the the external call comes in (NO CLI) to 2482 (the switchboard) (Timestamp Jul 11 14:01:02.199)
The 2482 in this case hase a CFA to an external numbber (0115789352, but you do not see it) the outbound call as you can see at timestamp Jul 11 14:01:06.219 has the Called party number of 2482 and not the 0115789352
there is no outbound call. Both are incoming setup, call reference 0x36. The router then rejects the call with "Service/option not available" but it is not clear to me the reason why.
I suggest you to upgrade to 12.4(11)XJ4 that has the most bug fixes in ISDN and is the most stable. Also it would help if you configure "isdn tei-negotiation preserve" under each BRI interface.
Finally, unrelated to the issue, if ou configure each BRI port with trunk-group (with a name of your choice), then you will be able to reduce the number of DPs by referencing said trunk-group instead of port.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
