asterisk users - May 2007 - mISDN: long delay when making outbound calls

Hi,
I have an Asterisk 1.2.9.1 box connected to an ISDN line via a beronet 
card (with ports in PTP mode). I noticed a long delay when making 
outbound calls, more precisely between (taken from Asterisk CLI)  
"Called 1/XXXXXXXXX/s"  and  "mISDN/1-u43 is proceeding passing
it to
SIP/8-5486"
I searched on misdn.org but found nothing.
I'd like to understand if this delay is caused by telco line or the 
driver and in the latter case if there is a way to shorten this delay.


TIA
