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.
