Yealink NOTIFY message to Auto-Answer

[komfushee]

I've sent a SIP NOTIFY to the phone, but it did not seems to accept it.

Here is the NOTIFY event :

Code:

[event-talk]
Event=>talk
Content-Length=>0

And the sip trace :

Code:

Maybe is it because the "From" is unknown when sent from Asterisk CLI. Any idea how to make it work ?
