Features with sip phones

I have an cme 9 with 3905 sip phones and sip trunk. 100% sip. Everything works fine execpt features like hold, call waiting and transfer.

Something easy like take a call from an internal phone (or offnet call) and transfer it to another sip phone is not working!.

In the moment that I use the pause (hold) button, transfer button the current call is droped and get a dial tone again.

do I need setup somethink like service dsapp ??
