Here is a working extensions.conf section separating calls based on the MSN 
dialed by the external caller:

[isdn-in]
exten => s,1,NoOp,${DNID}
exten => s,2,GoToIf($["${DNID}" = "5551212"]?contexta,s,1:3)
exten => s,3,GoToIf($["${DNID}" = "5551213"]?contextb,s,1:4)
exten => s,4,GoToIf($["${DNID}" = "5551214"]?contextc,s,1:5)
exten => s,5,GoToIf($["${DNID}" = "5551215"]?contextd,s,1:6)
exten => s,6,Wait(60)


which first (1) logs the msn (just for debugging, you can of course get rid 
of that)

(2 - 5) send call to contexta,s for MSN 5551212; contextb,s for MSN 5551213 
etc.

and finally (6) just a 60 secs wait at the end (this is so that if I miss 
some extensions, other true ISDN phones may ring and their answering 
machine can pick up the call while asterisk justs waits silently)

(Can't help you with the other questions)

Cheers,
Phil
