[asterisk-r2] Outgoing call to a PBX interface is being dropped

Fri Feb 19 08:32:30 CST 2010

Ok. The problem with calls being dropped by the PBX was solved.
It was really the collect-calls-drop stuff.  Great. I am happy.

The problem now is that I am getting tons of  non-stop "Yellow Alarms"
filling up
my console.

"
Seems to be clock sync. I am using PSTN as time source.

span=2,1,0,cas,hdb3
cas=32-46:1101
cas=48-52:1101
dchan=47
echocanceller=mg2,32-46,48-52

What it can be ?

Thanks in advance,

Isamar
