Ext.Callback Translation with QSIG and ISDN trunk

[chodor]

I'm making connection between 4400 and Asterisk via PRA2. Everything works fine except Ext.Callback Translation (ECT). ECT rules works fine with ISDN trunk group, when I switch group to QSIG the rules doesn't work
I prefer QSIG becouse with ISDN I have name of trunk group on LCD after connection to Asterisk phone instead of dialled Asterisk number
