EPVPN Public Beta
The EPVPN Public Beta has ended
Since 17 October 2026, the former EPVPN Beta has been running in production under the name EPVPN. Existing accounts have been migrated and the old system has been shut down.
This page documents the former public beta. Read the switchover announcement (DE/EN).
EPVPN Beta
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.
Quickstart
- Select EPVPN Beta in the upper left corner –> My Extensions → Add Extension for EPVPN Beta
- Configure your SIP client as described below
Dialin
- PSTN dialin: no dialin for EPVPN Beta
- VoIP dialin: sip:XXXX@pbx-epvpn-voip.eventphone.de
Configuration
SIP user
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.
Events
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.
PSTN Dialplan integration (Germany)
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 designates the (0)199 range for internal network routing. See section 3(g) of the Bundesnetzagentur numbering plan for traffic routing numbers.
Dialplan Considerations
- 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
- 8xxx → IVR, Scripts, announcements, automated responses
- 9xxx → prefixes and routing
