[asterisk-dev] QSIG error -- can somebody explain?

[Wolfgang Zweimueller]

Hi all,

I tried to connect the bristuffed(0.3.0-PRE-1i) * to an Alcatel PBX
via BRI (zaphfc) and Q.SIG. The Alcatel PBX is connected to the
outside world and should forward our calls to the telco. This setup
works correctly as far as I use euroisdn as the switchtype.

The first problem was that it is only possible to run the * side in
CPE-mode -- I wanted NET.

Anyway, I configured * this way:

        switchtype=qsig
        signalling = bri_cpe
        facilityenable = yes

My experience now is that it is possible to signal a call (both
outgoing and incoming) but as soon as the callee takes off the hook
the call-setup crashes.

Below is the debug log of an outgoing call to a service number of the
telco which tells the current time. (The point is that the called
number immediately answers the call.)

As you can see the Alcatel side answers to our SETUP message with a
RELEASE COMPLETE and a cause number 100. This cause (taken from
ECMA-143) means: "Invalid information element contents"

,----
| This cause indicates that the equipment sending this cause has received an
| information element which it has implemented; however, one or more of the fields
| in the information element are coded in a way that has not been implemented by
| the equipment sending this cause.
`----

Can somebody explain what the problem is? Configuration error, a bug,
a problem on the Alcatel-side?

Thanks in advance,
Wolfgang
