My guess is you have a cabling problem and that span TE2/0/1 is going into and out of alarm. Each time it goes into alarm the core of DAHDI will look for a new span to use as a timing source for asterisk. If TE2/0/1 is the "preferred" timing source, when it comes out of alarm, DAHDI will switch the timing back to it. -- Shaun Ruffell Digium, Inc. | Linux Kernel Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: www.digium.com & www.asterisk.org -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
