asterisk users - Aug 2004 - Can only call asterisk once

I have Asterisk RC2 setup here with a Fritz ISDN card on Debian Woody.
I'm using chan_capi-0.3.5 and fcpci-suse8.2-03.11.02. Settings are 
pretty much the default, except in order to get the fcpci module to
compile, I had to follow the instructions here: 

http://www.voip-info.org/tiki-index.php?page=Asterisk%20AVM%20Fritz%20CAPI%20Driver%20Install

but the drivers would only compile if I left the CCFLAGS as they were.

Now I've been able to successfully call Asterisk from a POTS phone. We
have a block of 10 numbers that are on the ISDN line. Once I call one of
those numbers, no more calls will go through after that. I have to
restart Asterisk in order for it to answer another call.

Has anyone seen this behaviour before? It's certainly not ideal ;)

Thanks
