asterisk users - Dec 2011 - Struggling with Extensions in Realtime

Hello Everyone,

Can someone please let me know what the correct way to deal with
extensions for a particular user
using asterisk reatime. For a user 1001, we would like to support:

Local Calls: 123-456-7890
LD Calls:     1-123-456-7890
INT Calls:     011-64-03-123-456-7890
PBX EXT:    1002

Do I need to insert multiple records for use 1001, each pointing to
the different extensions in the extensions
table (i.e., local-context, ld-context, int-context, and pbx-context)?

Thanks in Advance,

Nick.
