The Phone Operation Center (powered by Eventphone) will be present at the EMF Camp this year providing site-wide DECT telephone access.

You can bring your own DECT telephone and join the network, enabling you to call other EMF participants and interactive services for free.


Use the DECT Phone Compatibility List to find out if your phone is compatible.


To secure your personal extension in advance please register for an account. Once logged in you can create a new extension - remember to set the type to "DECT"

Once you're in range of the network you can instruct your phone to join.

1. Find the "Register" option in your phone's menus. This varies between models, and you may need to do it more than once.

2. If you're prompted for a pin try 0000

3. Once your phone has registered, click the key icon within Guru3 and call the number shown to claim your personal extension

4. You're now connected to the network and call other users.

POTS (Plain old telephone service)

There will be a site-wide POTS network allowing you to connect a traditional analog phone to a phone line, with support for modems and fax machines.

For more information see CuTEL_HQ

External Calls


NO outbound dialing from SIP extensions!

You can dial every PSTN number you like from the fixed phones at the venue and also from the DECT phones. Outbound calls are limited to a maximum duration of 10 minutes. The call will be disconnected, reaching the limit. A warning beep will be played 30 seconds before. There is no need for a special prefix, just dial the number in national or international format. UK numbers don't need a country code. International numbers should start with double zero not plus.


You can receive calls on the camp network from the outside world, callers can dial;

   +44 330 053 2800 (UK)
   +1 313 631 2600 (US)

And then enter your extension number followed by #

Alternative way with DID (direct inward dialling)

Using this way you might call all extensions directly.

CAUTION: This might not work with every network operator. The number length might cause issues.
