[Freeswitch-users] freetdm dahdi permissions Debian - with debian packages installed.

OK - I found this:

2013-07-14 21:43:35.680082 [NOTICE] ftmod_zt.c:1451 Using DAHDI control device
2013-07-14 21:43:35.680099 [ERR] ftmod_zt.c:1460 Cannot open control device /dev/dahdi/ctl: 
Permission denied

So checking

/dev/dahdi# ll
total 0
crw-rw---T 1 root dialout 196,   1 2013-07-14 21:15 1
crw-rw---T 1 root dialout 196,   2 2013-07-14 21:15 2
crw-rw---T 1 root dialout 196,   3 2013-07-14 21:15 3
crw-rw---T 1 root dialout 196,   4 2013-07-14 21:15 4
crw-rw---T 1 root dialout 196, 254 2013-07-14 21:15 channel
crw-rw---T 1 root dialout 196,   0 2013-07-14 21:15 ctl
crw-rw---T 1 root dialout 196, 255 2013-07-14 21:15 pseudo
crw-rw---T 1 root dialout 196, 253 2013-07-14 21:15 timer
crw-rw---T 1 root dialout 196, 250 2013-07-14 21:15 transcode

So I added freeswitch to the dialout group

$ grep dialout /etc/group
dialout:x:20:asterisk,nut,freeswitch


But the error continues.

Doing
  $ su -s /bin/bash freeswitch
Then cat of 1 allows me to get data as freeswitch

Is freetdm running as a different user?

This is with a Digium, Inc. Wildcard AEX410 4-port analog card (PCI-Express) which works with asterisk.

Here is the 'interesting' bit from the log.
