I have little question.
Run anybody Digium TE410P and chan_ss7 with Siemens EWSD?

I have a problem.
Layer 1of ss7  run good, but upper layers dont' run.
In logs i see:

entering octet counting mode on link 'l1'.

I read faq for ss7. IRQs its OK. Line have one week tests. Tests was passed.
Is this possible to run te410 with siemens ewsd?
