asterisk users - Mar 2006 - qozap drops -- possible to bridge BRIstuff ISDN to analog zaptel phone?

Hi all,

Using Asterisk 1.0.10-BRIstuffed-0.2.0-RC8q
with a Junghanns quadBRI (2 spans connected) and a Digium TDM400 for
extensions

Shouuld I be worried about these lines that keep showing up in my
/var/log/messages?

qozap: dropped audio card 1 cardid 0 bytes 6 z1 10 z2 116
qozap: dropped audio card 1 cardid 0 bytes 6 z1 50 z2 28
qozap: dropped audio card 1 cardid 0 bytes 6 z1 59 z2 37
..
....


This may or may not be related to a problem I am having with incoming calls.

They seem to appear when my incoming calls keep getting dropped as soon as
you pick up the analog handset to bridge.
Call comes in, rings analog handsets........but then everything hangs up as
soon as one of the dialed handsets is picked up.


Stumped on this ISDN dialplan stuff...new to me


I've seen mention on voip-info about an edit to the qozap source -- 
http://www.voip-info.org/wiki/index.php?page=zaptelBRI
But that doesn't seem to be my exact problem, as system is loading, asterisk
runs..can dial out too!

suggestions appreciated!
