[Users] sending NOTIFY messages

[Mark Price]

Hi,

Are there any generally used methods for sending SIP NOTIFY messages
to a phone that is registered through openser?

I.e. for sending events to sip phones?

For example, I imagine a script that would register to the
mydomain.org openser server as an administrative user and send a
NOTIFY packet to user at mydomain.org.

I'm hoping not to reinvent the wheel here.
