pri_net config

Hi everyone,
I have a situation, I have used an Asterisk box as CO attached a TeleSynergy PBX using PRI connection, so right now the comuniations work between them, i can make outbound call and inbound call as well.
But the problem is when the TeleSynergy box uses the dialer to place calls, it make the calls but asterisk send back the response to it to fast and it can not deterninate if that call was busy, disconnect, or any other state, all of them are pass trough it as answered call because asterisk send that signal to fast to it. There’s any way that I can make that signal takes a little delay?

Or exist a monitor in asterisk that i can see if there are comunication errors between them?

I really apreciate that.
