Direct Dialling Inward (DDI)

A major feature of the university telephone system is the ability to dial in directly to an extension from outwith the University.

If you are calling a School or Unit extension prefix the number with 46 for extensions which are set up with the appropriate class of service.  Thus extension number nnnn may be dialled from outside the University on St Andrews 01334 46nnnn, or from outside the UK on +44 1334 46nnnn. However, not all extensions are enabled for DDI.

Student Halls of Residence bedroom telephones are not enabled for DDI, but use the prefix 01334 462222 and, at the prompt, followed by the room extension number. Information relating to these numbers can be obtained from theTelephonel office on extension 2100 or 7221.
