I need some help getting a system running for one of my company's
plants. I am running AsteriskNow 1.7 with Asterisk 1.6.2.10 and
FreePBX 2.8.0.2.
My D-Channel keeps bouncing. The telecom tech told me he thought that
I might be using the wrong sync source, and I think I might have been,
but I changed DAHDI system.conf to "span=1,1,0,ESF,B8ZS" (from
"span=1,0,0,ESF,B8ZS") and I am still having the same problem.
(Although, the FreePBX DAHDI page only allows me to select "0" in the
"Sync/Clock Source" field. "0" is the only option in the drop down.)
dahdi_tool is showing some "IRQ Misses" and is listing "Sync Source"
at the"Wildcard TE121 Card 0." But, dahdi_scan is returning
"syncsrc=1"
