Voice (IP)
Voice over IP Service
DEEC has a voice over IP infrastructure that has replaced the previous analog voice infrastructure.
This service is integrated in the infrastructure of the University of Coimbra, making it possible to make internal calls between buildings and departments within it.
The prefix for DEEC is 42. Thus, all previous local extensions of DEEC went from the previous 4 digits to 6. For example, the old extension 1245 in the VoIP system becomes 421245.

Network Time Protocol (NTP)
The NTP service is intended to synchronize the time between the various network devices. The Computer Network Management (GRI) office maintains a time reference (ntp.deec.uc.pt), synchronized with the central time servers of the University of Coimbra and other higher level references. The devices you want can sync with this local reference to keep your watch constantly updated and in sync.
To access the service, users must configure the device's NTP client by pointing to the ntp.deec.uc.pt (or 193.136.205.254) server.
Equipment Housing
Housing & Colocation service is available at the DEEC / ISR / IT Common Datacenter. This service is the colocation of the server or other computer equipment with network access.
Since the server is provided by the client, it will also be configured, administered and maintained (hardware) by the same. This way, its owner can install the software he wants as well as configure it carefully.
