Modernize what I have
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 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.
Coordinate agents, SIP and analog telephones, with access to approved local trunks.
Support finance, police, and civil affairs sites without requiring a single equipment type.
Connect legacy PBXs, E1/T1 services, analog telephones, and fax during the transition.
Use local SIP and analog service with LTE access for community centers and remote field sites.
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.

Document each department, the systems it retains, and the local, external, and inter-site calls that must work before migration.
