asterisk users - Feb 2004 - 7960 x SCCP/Skinny (off-topic)

I'm running * with a 7960/Skinny. I'm seeing several pages with
SIPDefault.cnf config file, but as I'm not running SIP for this phone
(yet), it is useless now.. Is there any Skinny/SCCP Default.cnf also?
Actually, I'm trying to enable the extra 7960 features, like directory,
services etc...

Thanks, Hermann

When I try to initiate a call from my Grandstream phone (ext 8010) to my 
firefly softphone (ext 8030) I get the following error messages, but  I 
have no problem calling from firefly ext to grandstream ext. Calling 
from a Zap phone to firefly works fine also.
