From 36C3 Wiki


The Phone Operation Center (powered by Eventphone) will be present at the 36C3 this year again with a mobile DECT system and phone infrastructure. After setting up many base stations most of the Messe Leipzig is covered by DECT mobile telephony reception.

You can bring your own DECT phone and register it at the 36C3. So you will be able to call other 36C3 participants for free. Please claim your Extension in GURU3.

Use the DECT Phone Compatibility List to find out if a phone is known as definitely working or definitely not working.

This year will be the 18th consecutive congress with Eventphone.


Since 34C3 things have changed a bit. Waiting in line is no longer necessary to register your phone. We have a blog post describing our new registration process. We even made a video for you. Unfortunately, it is in German only, but english subtitles are available.


We have outside connectivity via SIP trunk. PSTN Dialin: +49464438299 < Extension>


It is also possible to dial external German landline and mobile phone numbers. This service can only be used from the DECT and GSM network to avoid abuse.


There will be a GSM network this year see → GSM.


The Phonebook is available at GURU3. It can also be accessed via LDAP or CardDAV

After the Congress

If you don't need your DECT phone anymore after the Congress consider giving it to the POC for organizing future events.


Between Events you can still be connected to us. Register a Number in our EPVPN.
