Like our virtual phone network EPVPN, the Beta Version can be seen as a long term event in between all the other events. But the new Public Beta has several advantages and is more like our phone system you already know from our temporary events.

You can use functions like forwarding, announcements, ringback tones, groups, pause in groups and multiring. At this moment there is no dial-out.

Currently, is not possible to set up a forward from our temporary events to an EPVPN Beta extension and vice versa.

1. Log in with your eventphone account or Register before.
2. Select EPVPN Beta in the upper left corner –> My Extensions → Add Extension for EPVPN Beta
3. Configure your SIP client as described below

• PSTN dialin: no dialin for EPVPN Beta
• VoIP dialin: sip:XXXX@pbx-epvpn-voip.eventphone.de

Technical Data:

• SIP proxy: pbx-epvpn-voip.eventphone.de
• SIP username: your extension number, e.g. 1234
• SIP password: your password as listed on eventphone.de
• SIP port: 5060 UDP or Port 5061 TCP/TLS
• RTP ports: dynamically assigned between 10000 and 20000
• Behind NAT? Don't forget to send keep-alive packets every minute or so.

There is no bridge prefix to our temporary events right now. That will be available, once we switched the current EPVPN to the new software.

Users of PSTN numbers may configure 01999 as prefix for eventphone, which is set up to loop back to itself - so e.g. 01999-0310 will be reduced to 0310. This loopback feature comes in handy when configuring devices such as the Fritz!BOX that can switch between VoIP providers based upon different prefix numbers.

The German numbering plan reserves a range (0198 - 0199) as prefix for network internal routing. Thus the prefix 01999 should not conflict with any assigned national prefix.

• 0… → prefixes and routing
• 0310 → network announcement
• 1xxx → reserved for hacker spaces (call us if you need one)
  • 16xx → reserved for VOC
• 20xx → reserved for PoC
• 2100 - 7999 → ordinary user extensions
