Envoyé : vendredi 17 avril 2020 17:16 À : freeswitch-users@lists.freeswitch.org Objet : [Freeswitch-users] Device / extension state (status) functionality at Freeswitch or get User (Peer) / Gateway (Trunk) state There is Freeswitch 1.8.5 built from sources worked on x64 Linux. I need to check / get internal users / trunck gateways state BEFORE using it to perform different actions in response of got conditions: 1. the called number is not exists in the directory at all; 2. the called number exist in the directory, but not registered at the time, for example don' t launch softphone; 3. the called number is inuse; 4. the called number is busy; 5. the called number is not answered due timeout 6. the called number is answered. Is there functionality looks like device and / or extension (user) state at Freeswitch as for example <dialstatus> or <channelstarus> ? How is the best way to get these different states for internal users, for each one and /or for trunk gateways, per each also ?
