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.
