[Asterisk-Users] SIP Gerenal settings conufsion

[Jeffrey Starin]

I have a little confusion about the general settings (other than the 
register values) in the SIP
General area. I understand that for examle in a SIP context like [FWD] 
or [BROADVOICE]
the entries in those areas are ths settings that take effect in any
 communication woth FWD and/or BROADVOICE.  However, I'm confused as to 
the purpose of the
"general" settings -- to what or which connection do they apply?  Since
 the context suggested for the general settings is something like
 "nothing" to avoid unwanted sip calls, I'm confused as to the purposse
of values in the general section since all parameters for communications 
with VOIP providers is contained in the contexts such as I specified 
above, i.e., [FWD] or for example [BROADVOICE].  Can someone shed some 
light on that for me?

Thanks,
