Phones

Overview

The Phone Operation Center (powered by Eventphone) will be present at the EMF Camp this year with a mobile DECT system and phone infrastructure.

After setting up many base stations most of the EMF is covered by DECT mobile telephony reception.

You can bring your own DECT phone and register it at the EMF. So you will be able to call other EMF participants for free.

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 first EMF with Eventphone.

Registration

To secure your personal extension in advance please signup and register your DECT/SIP/GSM extension here.

Dialin

For External Dial In you have 2 options;

Callers can dial 07520 660 900, you will then get dialtone and can dial any number as if you were on site (no external access to dial back out though!)

If you would like to have your own direct dial number we can offer this with the help of our sponsor Nexmo

1. ) If you don't already have one signup for an account at nexmo.com
2. ) In your account dashboard add the coupon code CFMEAC18
3. ) Now purchase a number in your desired country
4. ) Configure the Voice setting for that number as `Forward to SIP` at [YOUR EXTENSION]@voip.eventphone.de

Dialout

You can dial external numbers in UK, USA and Europe, If you need another country opened up please come and see us in the Badge Tent.

UK Numbers can be dialed in their regular national format eg 07700 900000.

International numbers can be dialled with a + or 00 prefix followed by the international number, eg for the USA +1 212 555 1212 or 001 212 555 1212

Optionally you can prefix external numbers with a 9 if you like that sort of thing.

DECT

If you've brought along a DECT phone then you can add it to the site wide DECT network that [Eventphone] are bringing with them.

To do so, follow these steps:

1. Sign up for an account at https://guru3.eventphone.de/ - the login/signup button is the non-obvious arrow pointing at a square in the top right.

2. Select "My Extensions" and then "Add Extension", then "Add Extension for Electromagnetic Field 2018"

3. Select "DECT Handset" as the type, and then fill in the other details.

4. You should now see your extension listed under "My Extensions".

5. Find the "Register" option in your phone's menus. This varies between models, so you'll have to find it yourself.

6. Once your phone is registered with the network, click the key icon next to your extension and call the number listed.

7. You're now on the event phone network!

DECT Notes

If you're prompted for a base-station PIN try 0000

I had to scan for basestations twice on a number of phones (Gigaset C430) before I could register.

GSM

SIMs

All attendees will get one SIM with their badge courtesy of Hologram This will work with the on site network during camp for Voice and SMS. After camp you can register the SIM with hologram and use it as an IoT sim for SMS & Data.

If you need an additional SIM please come to the badge tent and ask, we have a limted additional stock so we might ask what you require a 2nd one for.

To use your badge after the event be sure to visit Hologram.io to activate the included SIM card. Activating the SIM card unlocks access to roam on Hologram's global cellular network. As a bonus Hologram has provided a $20 credit for each attendee. Use promo code 'EMF2018' when picking a cellular plan."

Coverage

We are aiming to provide the best coverage we can, however we only have 16 GSM base stations and these are running at very low power, signal inside things like temporary buildings may well be weak. We are hoping to post a coverage map here once the network is installed. This is the first time we have run this setup on this kind of scale therefore we will be optimising it as best we can across the weekend.

The proposed locations and CellID's of each BTS is as follows: (Note: this may change once we get on site to install them)

BTS	LAC	CID	ARFCN	Location
3	1	101	871	X1
4	1	102	872	D1
5	1	103	873	F3
6	1	104	874	First Aid
7	1	105	875	E2
8	1	106	876	Stage A
9	1	107	877	C1
10	1	108	878	Bar2
11	1	109	879	Bar
12	1	110	880	Badge
13	1	111	881	Stage B
14	1	112	882	NOC
15	1	113	883	A2
16	1	114	884	L2
17	1	115	885	Stage C
18	1	116	870	G1

Handovers

At present the GSM system does not support the handover of an active call, so if you are on the phone STAND STILL! if you go too far from the base station you started the call on it will likely drop. We hope to work further on this but it may well require additional hardware.

After EMF

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

EPVPN

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