Good news - we're open for limited services in Wembley. Ujima House is now actively under refurbishment and we'd love your help in making the space the best it can be.

Please pay attention to the main LHS mailing list or pop into our #london-hack-space IRC channel and say hello.

During this interim period donations and continued membership are greatly appreciated while we transition to our new space.

Internal Feature Codes

There are several internal feature codes. These can be dialled from any phone. Hopefully this list will grow in future.

Outbound Calls

Outbound calls to chargeable numbers are blocked, however its possible to dial Free and Emergency numbers. See below for details.

Freephone Numbers

Calls to 0800 and 0500 Freephone numbers are permitted.

Emergency Numbers

Outbound calls to the Emergency Services and Single Non-Emergency Numbers such as 101 are supported. However, as with all VoIP systems its strongly recommended that you use a fixed line or mobile phone where available. In the event of an internet or power outage, outbound calls will not work.

Peered Networks

The Hackspace Phone system is peered (connected) with other networks via SIP. If you wish to peer with other networks such as other Hackspaces, contact a maintainer.

When dialling a peered network, enter the required prefix followed by hash, then dial the number you wish to call.
