Hi all,

I’ have a T1 card from Digium and try to connect an Alcatel pbx with asterisk.
That’s work fine using euroisdn in my zapata.conf but i must use QSIG.

I try many configuration in my zapata.conf to make it work without success ! everytime congestion and i can t make call

Is there someone who experience this situation and using qsig.
