For the purposes of google since i'm sure someone is going encounter the same problem at some point in time...
I have now fixed the problem, it seems asterisk and swyx refuse to talk properly with euroisdn.. it now works by changing it to use qsig... on the swyx side: windows device manager > select the isdn card (sx2 dualpri) > advanced > isdn parameters > tick use additional d-channel features > tick enable q.sig restart the server asterisk side: modify /etc/asterisk/zapata.conf and set switchtype=qsig for your swyx trunks and one more thing... for wanpipe you need to set tdmv_dchan = 0 instead of 16 job done!
