I encountered this strange problem which is I can call into Asterisk box
but I cannot call out.

I was successful before using exactly the same euroISDN line but with
TE110 and different versions of Asterisk.

This time, I am using:
. TE410
. Asterisk 1.4.13
. Zaptel 1.4.6
. Libpri 1.4.2

1) I put the following into extensions.conf to get to the outside line
   exten => 0,1,Dial(Zap/1)


2) When I hit '0' on the phone, it came back like this on the console:

3) Something dodgy when I did a # cat /proc/zaptel/1
It complains that the channels are all "In Use" and I am only using span
