Several Mn/DOT facilities are paving the way to the future by serving as the initial installation sites for a Voice over Internet Protocol phone system for the department.
A VoIP system allows users to make telephone calls over a computer data network. VoIP phones talk to each other over the state’s private network or to ordinary phones via a public switched telephone network gateway. Mn/DOT VoIP phone calls never go over the Internet.
All of Mn/DOT will soon use the new computer network based phone system that will save significant amounts of money in the future. And, when the phone system is complete, Mn/DOT will fall in line with several other state agencies moving to VoIP.
“It will save money,” said Bob Bennett, project technical architect, Office of Information Technology. “A regular desk phone now costs us about $27 a month just to sit on the desk. The VoIP phones will cost about $11 a month to operate.”
This saving occurs because the state owns a computer network that connects all state agencies. Currently, the departments of Administration, Agriculture, Health and Revenue have moved to the new system. Bennett said the state Office of Enterprise Technology, which oversees the state’s computer and network operations, is encouraging all state agencies to move to this system.
Besides the cost savings, the system brings other advantages. The phones used for the system will have more features, such as call-waiting, than the current phones do. And once the phones are installed in all Mn/DOT sites, the agency will no longer pay long distance charges for calls made between phones in the network anywhere in the state.
Bennett said the initial investment to install the entire system will be about $2 million, which will purchase the new phones and some network equipment.
“The savings will allow the system to pay for itself in about three years,” he said. “Currently, we spend about $94,000 a month on phones. With this system, we will cut that to $47,000.”
There are some disadvantages, he noted. If the computer network it is using stops operating, the phones don’t work. However, power interruptions will not be a problem since the phones and network are protected by backup generator power at most sites.
In addition, everyone at Mn/DOT will be required to change phone numbers, which means that contact information on Web sites, business cards and letterhead will need to be updated.
“It has worked well in the other state agencies,” Bennett said. “We expect the transition to be smooth and that employees will like the system when it is installed.”
Currently, the Network Operations Center and St Cloud have the system in place. In September, the Baxter half of District 3 will complete installation along with the Materials Lab facility in Maplewood.
Funding has been secured for installing the system in two additional offices in the Central Office, the Office of Information Technology and the Civil Rights and Administrative Services office. Implementation will begin in September for both offices.
Division directors are working to find funding for the rest of the agency. The implementation schedule for the rest of the agency will be based on critical needs, and largest return on investment, Bennett said.
