AUGUSTA — Legislative leaders voted Wednesday to ask for bids to replace a 30-year-old phone system in legislative offices.

The Legislature has approximately 400 telephones in service that use an analog system, said David Boulter, executive director of the Legislative Council. Estimates show the state could save $35,000 to $70,000 per year once a new system allowing voice and data over the Internet is installed, said Scott Clark, information service director.

Clark asked for permission to put out a request for proposals to vendors to see what a new system would cost. Those bids will then come back to the Legislative Council — a bipartisan board of legislative leaders — for consideration.
