Any change you could give a dialplan and some information to make it a bit easier to reproduce? Thanks!

$cat ~/test.sh
#!/bin/bash
for((;;))
do
       for ((i=1 ; i<= 30 ; i++))
       do
               echo "Starting call $i out of 30"
               cp ~/1.call /var/spool/asterisk/outgoing/$i.call ; sudo chown asterisk:asterisk /var/spool/asterisk/outgoing/$i.call
       done

       for((j=64; j<=127; j++))
       do
               echo "Stopping channel $j (from 64 to 127)"
               asterisk -rx "channel request hangup DAHDI/$j-1"
       done

$cat ~/1.call
Channel: DAHDI/g1/123456789
MaxRetries: 0
RetryTime: 60
WaitTime: 30
Application: Echo

I am using a script to copy a call file to asterisk/outgoing. I call via a ISDN-PRI group (two spans) to the same two spans (the called is looped back to me by the provider, so i'm calling myself). In the dialplan, i Answer() and Echo().
