Summary:                    reload in console crashes priindication=outofband
setting
Description: 
we have a digium te122 card configured for euroisdn

dahdi-linux 2.1.0.4
dahdi-tools 2.1.0.2
libpri 1.4.9
asterisk 1.4.24

on centos 5.2

I tried it on different OS´s with different kernels and with differnet
asterisk (1.2.x && 1.4.x) / libpri (1.2.x && 1.4.x) & zaptel (1.2.x &&
1.4.x) & dahdi(2.0.x && 2.1.x) versions. 
The malfunction is present on all these combinations (except asterisk v
1.6.x with dahdi 2.1.x but I can´t go up to this version at the time.)

I set
...
switchtype = euroisdn
signalling = pri_cpe
priindication=outofband
...
in chan_dahdi.conf

With a fresh started asterisk everything works correctly.
When something like

exten => 1001,1,Busy(5)

comes in the extensions.conf the caller on the other side gets a busy
signal and then dropped.

But when I need to make changes and then do a "reload" in the console it
seems that the priindication=outofband gets overwritten!?

When this line comes in the extension.conf

exten => 1001,1,Busy(5)

the caller gets no busy signalling. He hears nothing for a long time (10 -
20 seconds) and then gets disconnected.

Only when I do a 
"dahdi restart"
in the console the busy signaling will be functional again. (Or after a
complete asterisk restart)
But both of these are dropping active calls (as the server is quite
busy).
