We don't use SIP but IAX instead.
Protocol doesn't matter in this case.
It all boils down to extensions.conf magic.
Hell, we even get all our numbers using only 1 account.

This is a snippet from our extensions.conf:

CUST001DID = XXXXXXXXa
CUST002DID = XXXXXXXXb

[incoming-from-provider]
exten => XXXXXXXa,1,Goto(CUST001,${EXTEN},1)
exten => XXXXXXXb,1,Goto(CUST002,${EXTEN},1)

etc etc etc

Works like a charm for multiple customers on 1 asterisk
cluster.
