asterisk users - Dec 2004 - How to verify if chan_sccp is working/built correctly?

Hi list!

I'm still trying to figure out why my cisco 7940 compatible phone is not 
working with chan_sccp at all while it works partly with skinny.

Is there any way to verify is chan_sccp compiled correctly and if it's 
behaving like it should?

Can I telnet to the skinny port and simulate a 'login' and
authentication
of a device?

Thanks for any leads!
