connecting an pbx with multiple bri-lines to an cisco3660 with viv 2bri S/T

hello,

i have connected an pbx with 4 isdn lines to an c3660 (ios 12.2.13T) with 2 2bri s/t nt interfaces. in addition the c3660 has one e1 interface to the pstn. so i will have 4 voice ports for the connection to the pbx. i have bound my dial-peers referring to the pbx to all my bri voice ports.

in the beginning all was working fine. but now, when an phone behind the pstn wnts to start an external call, the phone gets an busy signal. when i do an debug isdn q931 on the router i see that there are all b-channels busy. but when i do an show isdn stat the router tells me that there

are free b-channels.

could someone tell me whats wrong here? i have searched the bug navigator for this topic but i didn´t find anything.
