====== GSM Token ======

Starting with 27C3 the GSM handset registration is managed as self-service. Just follow this simple two-step process:
  - Register a new extension with phone type "GSM". Give the system a couple of minutes to synchronise with our in-house GSM provider. Relax. Maybe have a nip of your favorite caffeinated beverage, then proceed to step 2.
  - Dial the GSM token shown in the details view of your extension. This step completes the registration process and pairs your device/SIM with the event's GSM network. If you ever feel like switching devices or SIM cards, then just redial this number on your new device.

====== Notes ======
Of course, the registration can only succeed when operating within the correct GSM network, so please make sure your network provider has been selected accordingly before dialing any number. Selecting a network named 27C3 or some binary digits is probably not the worst choice.
