Hi Krzysztof,
thank you four your answer. I think that's only the reason why it does
not stay up with ss7linktest. I had a look at the source and it seems
the GRS is only sent if you use ss7linktest.
In asterisk i enabled the debug for this linkset and it looks different:

The complete debug is available here:

Sometimes is see this message: T4 expired!
Any suggestions are highly appreciated.
Cheers,
