[asterisk-users] unavailable state not reported to Cisco SPA50X phone

[Linux]

Hello Stefan,

 
Thank you for your answer. I was already afraid it is not in the standard. I will look into the custom device states.

 
thanks,

 
Hans

Hello Hans,

Thats exactly the problem you hit. Even the RFC or the phones support
something like an "offline" state for not available phones.

In asterisk 1.2 this worked but it was changed after this version to be
RFC conform. I have solved this problem by using a proxy in front which
checkes if a phone is registered and set back a 404 if its not online
(registered) but this is not a solution for you.

Maybe you can build some solution with an external script and setting
custom device states.

best regards

Stefan
