SIP Videocall

Hallo zusammen,
ich bin neu hier und bin gerade dabei auf einem Raspberry PI DoorPI zu testen (Version 2.5.0.4) Der Rasp-Pi hat eine Kamera, von der ich über den Webstream ein Bild bekomme. Nun möchte ich aber einen SIP Videocall einrichten. Mein SIP Client (Android Tablet) mit installiertem Linphone bekommt vom DoorPI den Anruf nur als Voicecall sobald der "Klingeltaster am Eingang 1 betätigt wird. Telefoniere ich mit anderen Android Tablets mit Linphone untereinander funktioniert der der Video Call. Alle SIP Clients kommunizieren über einen FreePBX Server im lokalen LAN. Der Video Codec auf allen SIP Clients habe ich auf VP8 eingestellt, da DoorPI nur diesen unterstützt. FreePBX mit Asterisk 13 kann diesen Codec.
Hat jemand einen Tip, ob ich in der DoorPi Config etwas vergessen habe einzustellen?

Hier ein Ausschnitt aus der DoorPi config:

[SIP-Phone]
video_codecs = VP8
video_device = V4L2: /dev/video0
video_display_enabled = False
video_size = uxga

Vielen Dank schon mal.

Beim Anruf des Teilnehmers finde ich leider keinen Hinweis auf einen Videocall (kenne mich zu wenig aus im VoIP). Habe deshalb die trace Datei angeängt

Habe jetzt nochmals den Trace Mode eingeschaltet und mehrmals den Taster betätigt. Hier kamen nun folgende Meldugen:

Ist da noch eine Einstellung am Raspberry Camera Modul notwendig bzgl. dem Videoformat oder läuft da noch ein Dienst, der die Camera blockiert?

Habs gefunden!
Ich hatte das RPi Cam Web Interface installiert. Es lief der Dienst raspimjpeg. Dieser blockierte die Camera für den Zugriff von linphone. Nach der Deinstallation von RPi_Cam_Web_Interface funktioniert es problemlos.
