Modernize what I have
Manage voice centrally from headquarters, department stores, boutiques, and temporary retail outlets, while adapting SIP, PSTN, LTE, and analog phone access to each site's scale and continuity needs.

Stores may use different lines, phone types, and local arrangements, while central teams still need consistent reachability and management.
A replicable voice design separates the shared calling model from the local access and continuity choices required at each store.
Provide large sites with local business calling and a defined continuity role for the site.
Connect central support and store teams through the shared extension plan.
Support analog phone access at small stores without changing the centralized management model.
Evaluate cellular voice as a defined backup role when coverage and policy allow.
A centrally managed voice platform links headquarters and department stores, while small retail outlets use analog phone access and each site retains the appropriate SIP, PSTN, or LTE trunks.

A common design reduces variation, but site surveys still confirm local lines, network, coverage, and endpoint needs.
Define extension, permission, routing, and management requirements.
Record trunks, phones, coverage, and local constraints.
Choose approved access and continuity roles for each store type.
Test local, external, and intersite calls before repeating the model.
