The current analog telephone system was shared by Nikhef, CWI and SARA. Last year the CWI updated to a VOIP system, Nikhef will follow in 2011, the plan for SARA hasn't been determined yet.

VOIP stands for "Voice over IP", which means digital communication over the local ICT network instead of analog communication over a separate infrastructure. With VOIP an integration of telephony and ICT is much more feasible than with the analog telephones. For example the telephone book ("telefoonboekje") of Nikhef can be maintained in the central user administration system (LDAP) and not on a separate PC connected to the analog phonesystem.

Over the past two years an inventory has been made of the wishes and demands to which a new phonesystem should comply. This discussion has been held on a technical, financial and functional level with a number of people at Nikhef. Since October 2010 a test of the VOIP system with 25 participants has been up and running. The system is now stable and ready to be deployed further.

Parallel to this development it was recently decided to also replace a part of the current infrastructure at Nikhef; this concerns the 'edge switches'. This is the equipment to which the desktops, laptops and soon also the telephones will be connected. The new equipment doesn't only offer more functionality for administration, but also more bandwidth (1 Gbps) for usage by connected desktops and laptops.

What's new??

  • Normal phone.

The normal office phone on the desk or at the wall will be replaced by a similar version of an VOIP phone. It is connected via a usual network cable to the network outlet (which will also provide the power to the device).

  • Tracer.

The tracers are going to be replaced by wireless DECT telephones. Who will come into consideration to get a DECT phone instead of a usual (local office) phone will be decided together with the supervisor. The 'BHV-ers' (Emergency Response Officers) receive new tracers that are connected to a separated WCW system.

  • Functionality.

The VOIP control centre that replaces the current analog one offers the possibility to programme many special functions. For now only the known standard features will be implemented.

  • Administration.

The system administration of the new VOIP telephony at Nikhef is transferred from the Facilities to the CT group. There is a project group responsible for the supervision of transition of the old to the new system. The members of this project group are: Ahmed Azhir, Wim Heubers, Paul Kuipers, Tristan Suerink and Bart van der Wal. As soon as the new system is in place the support will be assured by the CT helpdesk.
