[asterisk-r2] Continuously Changing States

Mon Dec 5 13:00:52 CST 2011

*Dear All: *
*             I have a Siemens SDE connected to an Asterisk, but bits are
changing all the time. What could be happening? I am attaching versions,
configuration files and logs. Any help is very welcome. Thanks in advance.*

*Debian Squeeze  2.6.32-5-amd64*

*DAHDI Version: 2.5.0.2*

*Asterisk 1.6.2.20*

*Digium TE122 *

*openr2-1.3.2*
