Has someone else noticed that SIP Profile may not register sometimes.
I Have created sip profile and I use it from my application. Usually it works fine, but sometimes
program does not get profile to register. If I go to settings->connection->SIP-Settings and I change profile to
always on. That may help, but sometimes only way to get it work again is reboot phone.

If someone has find out good way to "reset" SIP-Stack/Profile let me know.
