Kategorie: freepbx

Nach einer längeren Testphase von 3cx, stellte sich heraus, dass 3CX bei allen Themen rund um Presence nur am eigenen Sofphone richtig funktioniert. Völlig uninteressant wenn man ein echtes VOIP-Telefon hat, dass die Funktionen ordnetlich abbilden könnte.

freepbx ist da out-of-the-box wesentlich besser zu steuern.

DND war relativ einfach umzusetzen, da die hints schon vorhanden waren. Ich habe aber einen anderen Status verwendet, um echtes Läuten des Telefons und DND zu unterscheiden.

nano /etc/asterisk/extensions_override_freepbx.conf

[app-dnd-on]
include => app-dnd-on-custom
exten => *78,1,Macro(user-callerid,)
exten => *78,n,Set(CONNECTEDLINE(name-charset,i)=utf8)
exten => *78,n,Set(CONNECTEDLINE(name,i)=Do Not Disturb: ON)
exten => *78,n,Set(CONNECTEDLINE(num,i)=${AMPUSER})
exten => *78,n,Answer
exten => *78,n,Wait(1)
exten => *78,n,Set(DB(DND/${AMPUSER})=YES)
exten => *78,n,Set(STATE=ONHOLD)
exten => *78,n,Gosub(app-dnd-on,sstate,1())
exten => *78,n(hook_1),Playback(do-not-disturb&activated)
exten => *78,n,Macro(hangupcall,)

Warum auch immer werden extesions von freepbx korrekt als unavailable erkannt, wenn die Identity sich abmeldet, aber der Status des hints hüpft nicht auf Unavailable.

Also schnell ein kleines python script gebaut, das alle 5 Sekunden die extensions kontrolliert und den hint aktualisiert wenn notwendig. Ginge vermutlich sauberer, wenn ein Script dauernd läuft und das event abfängt, aber egal.

import asterisk.manager

endpoints = {12,13,14,15,16,17,18}

manager = asterisk.manager.Manager()
check_update = [] #extensions to check for update
update = [] #extensions to update
try:
    # connect to the manager
    try:
		manager.connect('localhost')
		manager.login('logoff_user', 'PASSWORD')

			start = str(response.data.encode('utf-8')).find(str(endpoint)+'/'+str(endpoint))
			end = start + 70
			test = data[start:end].find('Unavailable')
			if test > -1:
				#extension is Unavailable
				check_update.append(endpoint)

			start = str(response.data.encode('utf-8')).find(str(endpoint)+'@ext-local')
			end = start + 60
			test = data[start:end].find('Unavailable')
			if test == -1:
				#extension is Unavailable
				update.append(endpoint)
		for extension in update:
			response = manager.command('devstate change Custom:DND'+str(extension)+' UNAVAILABLE')
			#print(response.data)
		manager.logoff()
    except asterisk.manager.ManagerSocketException as e:
        print "Error connecting to the manager: %s" % e.strerror
        sys.exit(1)
    except asterisk.manager.ManagerAuthException as e:
        print "Error logging in to the manager: %s" % e.strerror
        sys.exit(1)
    except asterisk.manager.ManagerException as e:
        print "Error: %s" % e.strerror
        sys.exit(1)

finally:
    # remember to clean up
    manager.close()

weil das Script alle 5 Sekunden laufen soll, hilft mir cron nicht, das kann nur ganze Minuten. Hier habe ich aber was gefunden das wunderbar klappt: https://stackoverflow.com/questions/9619362/running-a-cron-every-30-seconds
