I would like to determine state of UAS ( DND, forward calls turned on my remote sip phones.
When I send options method to remote sip phones I always receive SIP/2.0 200 OK response regardless of activated call features (DND, forward)
How can I distinguish different state of UAS ?
From my (limited) understanding, OPTIONS is used to determine which
methods, etc. are supported by the UAS - and not to determine what subscriber features are enabled. Are you trying to retrieve this information from a proxy or a phone? It seems like in either case SUBSCRIBE and NOTIFY would be better methods. But I'm not sure if there is a standard way to communicate feature activation states.
