Polycom 4.0.4 SIP

I am configuring freshly installed Asterisk 1.8.xx with Polycom SoundPoint phones. Downloaded ROM Uploader and 4.0.2B SIP. Updated couple phones and tried to provision them. No matter what I put into sip.conf file, I am getting “Wrong password” error during sip registration in Asterisk.
Downgraded to 3.3.2 and it registered right away.
Is anybody knows what is going on?
