I did get this working by changing the owner of the device to freeswitch. This does not make sense as asterisk was able to access the device by being a member of the dialout group. I'm wondering if this is a problem in freetdm ? $ grep dial /etc/group dialout:x:20:asterisk,nut,freeswitch /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 -------------------------------------------------------------------------------- Karl Schmidt EMail Karl@xtronics.com Transtronics, Inc.
