Summary:                    reload in console overwrites 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).

This is an old old old bug...
Also here in Italy we use priindication=outofband and i always had this
problem, from version 1.0.
Can someone see this issue?
