That's it.

2008-06-28: I forgot to enable the apache module when compiling php4. Easy enough to fix. Also, I needed to add current directory to the include directive in names.php (callid). Must check if that error is in the port as well.

2008-06-26: installed revision 755 of ISDN4BSD from svn, rebuilt kernel and now the ISDN card is detected. dmesg output. How to find out revision using svn:
tingo@kg-web2$ pwd

I still can't get neither isdntrace nor isdndecode to output the old (text-based) format.
2008-06-24: using cvsup, I upgraded to FreeBSD 6.3-stable. It took almost two days. dmesg output. I need to get latest ISDN4BSD from svn and install it.
root@kg-web2# uname -a
FreeBSD kg-web2.kg4.no 6.3-STABLE FreeBSD 6.3-STABLE #0: Thu Jun 26 16:07:14 CEST 2008     root@kg-web2.kg4.no:/usr/obj/usr/src/sys/T4ISDN  i386

2008-05-29: installed ISDN4BSD version 1.5.10 and compiled a new kernel. That got the ISDN card working again. dmesg output. Unfortunately, it seems that changes in the output format of isdntrace makes the callid port non-functional. More investigation needed.
2008-05-28: I upgraded the machine to latest FreeBSD 5.5-stable. dmesg output. The ISDN card is not working after the upgrade, need to get a newer version of ISDN4BSD installed.

older: the machine has been running FreeBSD 5.4-prerelease for ages. I am using the port callid as a call logger. works nicely. It seems the machine was installed in 2004, but the oldest evidence I have on the machine (kernel config files) are from 2005.
