callback problem between cisco and ascend

does anybody know if callback work well between cisco 1700 and a ascend pipeline 50 ?

I'm trying to setting up a callback but it doesn't work. what happen is :

1 - the ascend router initiate the call

2 - the cisco router doesn't close the first call initiated by the ascend router,

3 - the cisco router keep the first call, and initiate the callback on the second channel.

when I type the command show isdn active, I see 2 active connection "IN" and "OUT". Normally I should seeonly one active connection "OUT".

If only one channel is available on the ascend router ( for example one channel is alredady used to connect to another device (not the cisco one), the first call can be initiated but the callback doesn't work.

How can I force the cisco router to close immediately the first call ?

is there specific interface command to use to perform a callback with a non-cisco device such as ascend ? if anybody have a example configuration which work with ascend, thanks to show it.

thank in advance for you help !
