Thanks a lot for your debugging so far.  It is very helpful to get
qualified bug reports.

That would be me.

What would be most helpful is two pcap files of the communication. One for
the working and one for the non-working case.

Specifically the RSL CHANNEL ACTIVATE meessage is most important in that

I think with the pcap it will be very easy to solve the problem.

And yes, I have your other mails, but the day only has 24 hours, sorry...
