Thank Dave do your advise. Please advise me further, how do I verify the CICs and T1-1 (do u mean time slots?) are line up correctly? I can meet the telco engineer but need to explain to him properly and make my point. Unfornately, he doesnt know asterisk :( (only knows his huawei switch). By the way, i forgot to mention, when I turn on crc4 (in my dahdi/system.conf), the link just starts coming up and down every time!
