Hi,
easy to reproduduce the problem:
I started 2 asterisk on the same box, in the box is a TE405
asterisk -cvvvp
asterisk -cvvvp -C /etc/asterisk2/asterisk.conf
connect 1-2 and 3-4 ports crosslink E1 cables
I make a call to box1 (SIP), chain the call between 2 asterisks
(dialplan) using all ss7 circuits, end terminate an apllication ag.
Milliwatt.
exten => _66XX,1,NoOp
exten => _66XX,2,Dial(SS7/test/$[${EXTEN} + 1])
exten => 6630,1,NoOP(${EXTEN})
exten => 6630,2,Milliwatt()
Its works fine, everything is ok.
Now stop the box2 with CTRL-C, start again.
box1 hangup all the channels, ss7 linestat indicate all the channels are
idle, but I cant use all the circuits:
