[asterisk-users] Asterisk registrations - state?

Hi.

I'm using Asterisk 16.2.1 with some registrations (ie: my Asterisk server is 
registering to other PBXs as though it were a telephone).

Is there any way I can get presence / state information from those PBXs in the 
same way that a registered telephone can?

In other words, can I send a Subscribe request to the PBX so that I get Notify 
announcements about other extensions and whether they're idle / busy / ringing 
/ etc., the same as BLF indicators on a SIP phone can do?

I've looked at 
https://wiki.asterisk.org/wiki/display/AST/Querying+and+Manipulating+State but 
this appears to be only for the state of clients registered to my Asterisk 
instance, not for the state of clients registered to the same remote PBX as 
Asterisk itself is registering to.


Thanks,


Antony.
