-== Poll 
-* Headsets mit button sind schwer zu finden / teuer 
-* Schalter an Stativ muss jedes mal fest gemacht werden  
-  * Attach the button fixed to the tripod handle (endcap to leave room for zoom buttons on handle itself?) and connect it to the tally using connectors (something robust). Connecting button to the tally is a problem for each "solution". (Bix) 
-* Fussschalter brauch platz im case

 +* [Thorti] Unterschiedliche Configs für Tallycom (Kamera vs. Mischer/VOC-Office). Kamera= LED leuchtet, wenn Cam in Verwendung; Mixer/Office= LED leuchtet, wenn jemand im Channel spricht
 +* [Thorti] Möglichkeit für SaalAV-Mensch in mehreren Räumen gleichzeitig zu hören, aber nur in einem zu sprechen, um z.B. im Kanal zwischen Kamera/Mischer zu agieren und gleichzeitig im VOC-Channel erreichbar zu sein.
 +* [Thorti] Beltbak-Lösung für mobil mit WLAN (Halterung mit Gürtelklammer?). Stromversorgung via Powerbank.

 +=== tally (new version)
 +
 +The new version of the tally software uses all three colors of the LED:
 +* red indicates the source being live
 +* green indicates the source being in preview (pending support in Voctocore)
 +* blue indicates a loss of connection to the Voctocore host
 +
 +It shares much code with the Voctoknopf software and is therefore hosted in the same repository.  Installation works as follows:
 +
 +  $ git clone https://github.com/rlutz/voctoknopf
 +  $ scp -r voctoknopf/src voc@10.73.1.15:tally-src
 +  $ ssh voc@10.73.1.15
 +  ~ $ cd tally-src/
 +  ~/tally-src $ make all-tally
 +  ~/tally-src $ sudo make install-tally
 +  ~/tally-src $ sudo vim.tiny /etc/tally.conf
 +  ~/tally-src $ sudo reboot
 +
 +When replacing the old software with the new one, don't forget to disable the old ‘voctolight’ service before rebooting.
 +
 +Once installed, the configuration can be changed as follows:
 +
 +  $ ssh voc@10.73.1.15
 +  ~ $ sudo vim.tiny /etc/tally.conf
 +  ~ $ sudo systemctl restart tally
 +
