I've been setting up a few systems recently with a SIP account and an IAX 
account (same passwords, CLI, etc.) and having the users use a SIP 
hardphone for the office desk, and an IAX (idefisk) softphone for 
out-of-office calls. (My Dial() calls both accounts, so both phones ring)

It saves hassles with NAT, etc. for remote SIP phones too.

No good if you only have SIP phones though!
