===Dial Plan Considerations=== | |||
VoIP phones have a configurable "Dial Plan" that decides when a call should be sent to the server. A good dial plan improves the user experience, as it means they don't have to press "dial" or wait for a timeout to kick in. The dial plan should also handle users prefixing calls with a 9, as this has become a (bad) habit for some. | |||
The table below lays out the numbering plan used in the Hackspace. Emergency numbers should ''always'' go straight out, and the dialplan should be ordered so the user has to wait the minimum amount of time before the call is placed, eg an 11 digit number starting with a 0 should go straight out. | |||
