An Institute of National Importance

The Telephone Exchange at NIT, Rourkela, offers both Analog and IP telephony services across the campus, powered by a contemporary "AASTRA MX-ONE SERVER" telephone exchange. This system is divided into two sections, LIM-1 and LIM-2, with LIM-1 serving as the primary exchange supporting Academic buildings, Hostels, and select Residential areas, while LIM-2, located at the Estate Office, primarily serves residential areas. Capable of managing up to 10,000 lines with Direct Inward Dialing (DID) capabilities, the exchange currently supports 1,000 IP and 2,000 analog extensions throughout academic facilities, Halls of Residences, and living quarters.

For external connections, the exchange utilizes a Primary Rate Interface (PRI) line provided by BSNL, ensuring round-the-clock operator service, maintenance services during business hours (8X5), and 24/7 support for urgent and emergency needs.

Internal telephone numbers within this directory are four-digit (EPABX) numbers, with those starting with 2, 3, 4, and 5 being directly accessible from outside the institute using the DID feature. To connect, callers can dial 0661-246XXXX from within India or +91-661-246XXXX from overseas, substituting XXXX with the specific four-digit number.
