Hi all This question is not connected directly wiht Asterisk but I didn't find another place. Sorry, I would like to determine state of UA ( DND, forward calls turned on my remote sip phones.) Which tools should I use ? sipsak ? maybe something else. 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 ?
