GridPBX

Service level

The GridPBX is an experimental service. We do not offer any service guarantee, neither express nor implied, about the suitability of this PBX for any purpose, in particular not for voice conversations. The GridPBX is operated by the PDP group as a playground, meaning that the number plan, connection details, hostnames and PIN codes may change at any time. We will try to keep this Wiki page up to date.

Security

Some services reachable from this PBX incur fees for Nikhef or for specific individuals in the PDP group. In most cases, such services are protected by a PIN code. If you care given the PIN to access these services, you must keep this PIN private and secure. Do not write it in emails and do not glue it to your phone or terminal.

Your connection details to register an extension with the GridPBX are also personal and private. Do NOT share these data with anyone, keep them private, and do NOT give them to your colleague, not even for testing. They are yours.

Privacy

This is not a public or corporate phone exchange, it's an experiment. Traffic logs will be kept for evaluation purposes, and traffic data may be kept for a period as long as two years. On the other hand, it may also be destroyed immediately. Conversations traversing the GridPBX MAY be recorded, including both person-to-person calls as well an conferencing and bridging connections. These recordings are usually available only to adminitrators of the GridPBX, but in the case of a securit incident they MAY be exposed to anyone in the world.

PLEASE do NOT make private calls through the GridPBX!

Also, note that everyone in the world will be able to call your extension directly with a SIP URL.

Connecting to the PBX

All GridPBS numbers are experimental and unsupported unless you do it yourself ;-)

Registering an extension

Registration if individual extensions is closed!

To register your own SIP phone with internal phone number, please send a request by email to <grid.support@nikhef.nl> with the following information:

Your full name
ikonet/hefnet/windows login name
current extension number old PBX
preferred voicemail PIN
Enable voicemail (Yes/No)?
Email address for voicemails:
Enable call-waiting with music (Yes/No)?

When we have completed the setup, you will be issued with an extension number (not necessarily the same one that you have now!) and password to register your SIP phone

SIP connection parameters

Connect to windmolen.nikhef.nl (194.171.96.50) on port 5060/udp (default for SIP). Your registration URL will be formatted like

extension:password@windmolen.nikhef.nl

You can of course also make a (even parallel) SIP connection from your home. Just create a new internetphone on your Fritz!Box and point it to windmolen.nikhef.nl. You can then call for free from your home to Nikhef by selecting the proper prefix. And from there you can call EVO, or CERN again (if you have been assigned an outbound-PIN).

National number dial-in and the IVR

You can dial +31 (0)20 716 5293 to access the GridPBX Interactive Voice Response system. You'll be presented with a selection menu (like if you dialled 5293 from your own internal SIP phone).

NDPF IVR

The Interactive Voice Response behind number 5293 (from outside: 0207165293) is the current main entry point for outside users and supports multiple inbound connections. The obvious choices are

digit	Destination
1	CERN Vidyo gateway
2	EVO bridge
3	SURFnet MCU (hdmcu1) booked conferences
4	Talk and Vision MCU (rooms 50602 and 50603)
5	NCF conference 84143 (PIN protected)
6	Grid "MeetMe" Conference Bridge (842xxx conferences)
7	Nagios status of the NDPF
8	DISA, protected with your personal DISA PIN. Request this PIN from the grid group

Calling CERN

This is no longer possible.

CERN Vidyo dial-in service

Call +31 20 7165248 to connect to CERN vidyo confs, giving the extension (usually 1... for personal rooms, or 9... for Indico rooms) when thus requested. If you are physically at Nikhef: from an internal phone, you can also call 2263 and call for free for an infite period. Use this number (0205922263) also if you have a Nikhef Vodafone mobile and you are in .nl (that's also free ;-)

EVO phone bridge service

Calls to the EVO bridge are free, just call *84002 from within the PBX (or through the DISA), or select "2" in the NDPF IVR. To call the EVO bridge from your own landline phone or mobile, call 020 716 5293 and then select "2".

We foresee the end of the EVO phone bridge (...5293, dial "2") any time now, since EVO is going commercial.

Using the conference rooms

Call 020 716 5293 and press 3, or dial 5555 from within the PBX or through the DISA. You should then enter your conference ID and (optionally) the PIN code.

There are only scheduled conferences now, the persistent rooms have been discontinued. There is a permanent free love room with ID "15001" and no PIN.
