The Commonwealth Link to Interoperable Communications (COMLINC) system recently helped find the missing Louisa teen Isabel Hicks.
The system allows different agencies to make the same call simultaneously through the 911 Center.
The General Assembly now allocates $6.5 million in the national budget for the 2018-2020 biennium to ensure that COMLINC is available at each dispatch center.
Virginia public safety officials say COMLINC will help reduce "avoidable delays" in emergencies. Radiocommunication software allows dispatchers in one region to connect directly to emergency responders in other regions, including state and federal agencies, through Internet-based systems. A three-way call or video conference that can be used to talk to multiple people in different regions.
Since these groups are in a unified state, public security officials say it is easier to get information when events across county boundaries occur.
Virginia Interoperability Coordinator Tom Crabs said: "It uses program bridging technology to ensure that the radio system of the state agency is available in our region and vice versa."
State officials hope that by the end of 2022, all dispatchers in Virginia will be trained to use COMLINC.
