Central administration
Coordinate extensions, permissions and intersite calling from the shared voice design.
Connect government offices across networks.
Create a shared voice plan for central offices, departments and local sites while retaining required phones, PBXs and trunk access.
The public-sector estate
Unify offices across generations of voice systems.
A central office, department and local service site may not share the same PBX, trunks, phones or network readiness.
A phased design connects these environments through distributed UCP and SIP while assigning explicit local roles to analog, digital and cellular access.
Departmental office
Connect local users while retaining the approved access for that building.
Existing PBX or phone estate
Use analog or digital interworking during a phased modernization.
Site-level voice path
Define local trunks and qualified continuity behavior for each office.
Facility voice roles
Map each area to the voice role it needs.
Distributed UCP provides intersite communication, SIP connects voice systems and gateways bridge the local analog or digital estate.
Central office
Shared policy and call management
Departments
Distributed extensions and local users
Legacy environment
PBXs, analog phones and digital trunks
Local continuity
Model-specific or alternate path design
Move from institutional inventory to a governed rollout.
The design documents each site, the systems being retained and the acceptance criteria for intersite and local calls.
Inventory agencies and sites
Record users, PBXs, phones, trunks and local constraints.
Define the shared plan
Set numbering, routing, permissions and management responsibilities.
Design site transitions
Assign SIP, analog, digital and continuity roles per location.
Validate in phases
Test local, external and intersite calls before each rollout step.
Combine distributed UCP with the access each office needs.
Product choice follows site count, legacy interfaces, current trunks and the continuity behavior approved for the project.
