[SR-Users] How to send NOTIFY to UA

[CuiGang]

Hello,

Does any one know, how to send a NOTIFY message to a special UA?
Why I need to do this? I’m using kamailio integration with Yealink IP Phone. Yealink IP Phone can perform some specified action immediately by accepting a SIP NOTIFY message with the “Event: ACTION-URI” header. 
I want to use RPC or HTTP or NSQ or some other interface trigger kamailio ROUTE make a NOTIFY message and send it to a special Yealink IP Phone.

Thanks!

Regards,
