Ip Dialling - Sip Calling?

I need to ask if there is any builtin functionality for BlackBerry so i can make SIP calls without any software. I just don't want to have to launch an app every time i want to make a call. I'm looking for a way to store the sip settings, and the phone shall retrieve and use them whenever i want to call. Older Enterprise Nokias had such functionalitty, and i hope BB does too. For example.
