Hello,
I read on Yealink support that Yealink IP-phones expect
"Subscription-State:terminated" for there Presence/BLF-functionality.
So how can I get "Subscription-State:terminated" on Asterisk ?
That would be a bit strange as the subscription would then be
terminated, no more NOTIFY messages would go to it which would defeat
the purpose of subscribing to something. The only way to achieve that
would be to have the phone unsubscribe or to change the code to force
it to terminate the subscription under certain circumstances. This
would require knowing the exact specifications and details of what
they expect and when. Is there currently a problem you are facing with
subscription support?
Hello,
this "Subscription-State:terminated" is expected when the IP-phone goes
offline (Unregister or cut off from power).
At that moment indeed the IP-phone no longer sends NOTIFY messages.
Also, Asterisk knows very well the SIP peer becomes unreachable (see my
first post). But still Asterisk replies "Subscription-State: active" to
the IP-phones that request the state of the offline SIP peer.
Yealink expects "Subscription-State:terminated" so the Yealink IP-phone
can put out the BLF light (in stead of staying in a green mode, which
indicates that the SIP peer is still online but not in a call).
So I can follow the Yealink logic. Can you ?
Kind regards,
Jonas.
