Telephone and Fax Services

The telephone service runs as a cost recovery section, a policy designed to use budgetary controls to minimise wastage and excess telephone usage. Charges are levied at or below equivalent Telkom rates; and the cost recovery used to maintain and replace all equipment, and fund system expansion. All calls are billed at Telkom rates with exception reports being distributed each month both summary and full detailed reports.

All extension costs are accumulated and billed to the extension holder’s department monthly. The account is sent via email to the Departments where the total amount is debited directly from the departmental cost centre.

Fully detailed call reports are available on request, incase of an investigation. The Telephone Services Manager ext 2492 and the Telephones Administration ext. 8098.


Voice Services are provided through a range of devices, from simple analogue handsets right through to Mobile Apps on Smart phones.  A software client that can be loaded on a Microsoft Windows operating systems is also available for those users that require soft client functionality.  Features on the different handsets vary and it is advisable to contact the telephones section for advice on which handset is appropriate.  The convergence of technology has resulted in the use SIP (Session Initiation Protocol) VoIP Phones as a standard on UKZN’s IP network.  This obviates the need to have separate cables for voice and data.


Data services are provided via connectivity to a fully managed and switched Cisco Network.  All devices that are connected via an Ethernet cable to the network have a dedicated 1Gbs switch port.  Data services are also provided via secure 802.1x wireless network access using “UKZNDATA” as a standard SSID throughout UKZN. The use of “eduroam” SSID to support roaming services is also supported across UKZN on an ad hoc basis and is activated by calling the ICS Call Centre. All applications that reside on the network require authentication in order to make use of the services. All distribution switches that are used to connect access layer switches to the network are connected via 1Gbs uplinks.

UKZN connects to the SANReN (South African Research and Education Network) via a 10Gbs Metro Ethernet network that provides for redundancy through the use of a ring topology.  Internet traffic is differentiated into National and International components.  Based on traffic utilisation and budget availability, international traffic subscription is constantly being increased. There is no theoretical limit to national traffic other than the limits imposed by the underlying network architecture.

Subsidy Support for Mobile Devices

The telephone section administers the University’s subsidy support for privately owned mobile devices that are required by staff for business purposes.  This subsidy is effected in a split billing agreement with preferred cellular service providers, and includes the full range of devices – cell phones, smart phones, data cards and tablets available under contract with those providers.  Details of the terms and conditions of the subsidy support for mobile devices are set out in the Mobile Communications Policy.
