36C3 Phone registration is open


We are pleased to inform you that even with Resource Exhaustion the registration of telephone extensions for the 36th Chaos Communication Congress is open. Don’t get confused by the social media, it works without any voucher :-). You can claim your DECT, SIP or GSM extension in the Generic User Registration Utility (GURU).

Stay connected!
