High-volume public services
Coordinate agents, SIP and analog telephones, with access to approved local trunks.
Unify government voice across departments and service sites.
Integrate central offices, departments, and community service sites into a governed voice environment, so teams can call across sites while keeping local systems connected.
Public service estate
Assign each department a place in a governed voice network.
Public service sites often combine different call volumes, telephone estates, trunks, and levels of network readiness.
The delivered architecture integrates public service halls, finance offices, police departments, civil affairs offices, community service centers, and remote field sites into a single plan, with high-concurrency SIP, mixed local trunks, legacy E1/T1 and analog access, as well as LTE access at selected remote sites.
Mixed office environments
Support finance, police, and civil affairs sites without requiring a single equipment type.
Existing PBX estates and trunks
Connect legacy PBXs, E1/T1 services, analog telephones, and fax during the transition.
Community and field access
Use local SIP and analog service with LTE access for community centers and remote field sites.
Govern a single voice environment while allowing each public service site to retain the access it needs
Central voice governance provides shared unified numbering, permissions, and monitoring over an encrypted SIP network, while individual locations retain the SIP access, E1/T1 trunks, analog telephones and fax, or LTE access for remote sites required by their current estate.
Move from a site inventory to a governed, phased deployment.
Document each department, the systems it retains, and the local, external, and inter-site calls that must work before migration.
Inventory departments and sites
Record users, call volumes, PBXs, telephones, fax, trunks, and connectivity.
Define central governance
Define numbering, routing, permissions, monitoring, and operational responsibility.
Assign access to each site
Map SIP, local trunks, digital interworking, analog access, and LTE access for remote sites.
Validate department by department
Test local, external, inter-department, and remote-site calls before each cutover.
Combine central governance with the access each site needs.
Product selection follows department scale, call volume, retained PBXs and endpoints, external trunks, and approved remote access requirements.
A visible operating model for every department and site.
The design governs enterprise and public-service voice; any public safety, emergency service, or certification requirement requires a separate validation scope.
Central policy and visibility
Shared numbering, routing, permissions, monitoring, and reporting coordinate the estate.
Encrypted interdepartmental calls
Approved sites communicate over the shared SIP network while local roles remain visible.
Digital and analog interoperability
Existing PBXs, E1/T1 trunks, analog phones, and fax can be migrated in phases.
Site-specific LTE access
Community centers and remote field sites can include LTE access when required by the approved operating plan.
Build a governed voice plan for every public-service site.
Share departments, service locations, call volumes, retained PBXs and endpoints, current trunks, and remote connectivity priorities. OpenVox can map the approved inter-site architecture and access boundaries.
