It occurs to me, do you have the numbered extension set the same as the 
context name for the phone in sip.conf?   For example, in my sip.conf, the 
context names for each phone are [7001], [7002] etc.  However, this doesn't 
necessarily need to be true.   If it's not true, try:

mailbox=context name in sip.conf

instead.

so for example, if the extension is 7123, but the context name for the phone 
in sip.conf is fred, try:

mailbox=fred

Just a shot in the dark....
