Construction or project office
Establish business numbers and extensions for a site operating before fixed lines are ready.
Deploy business calling without fixed lines.
Establish business calling for temporary and rapidly deployed sites by matching cellular access, extensions and endpoint needs to the users and coverage available on site.
The temporary-site constraint
Start calling before fixed infrastructure arrives.
Construction projects, events and temporary offices can open faster than a fixed line can be provisioned.
A cellular gateway provides the external voice path while UCP or another SIP calling system connects the users and extensions required at the site.
Create a local calling system
Give the temporary site extensions and an external voice path without waiting for a permanent trunk.
SWG-4032 gateway
Up to 32 approved cellular voice channels presented to SIP
Plan the longer-term path
Define whether cellular voice remains primary, becomes backup or is replaced when fixed service arrives.
Temporary-site architecture
Build one portable path from cellular service to site users.
SWG-4032 supplies up to 32 approved cellular voice channels, UCP1202 provides the compact calling core, and SIP endpoints connect without requiring a fixed carrier line.

Confirm coverage and operator fit
Validate the cellular service before sizing the portable voice kit.
Keep the reference kit repeatable
Document SWG-4032, UCP1202, endpoints, power and network requirements together.
Plan the next site state
Define whether the temporary system moves, expands or hands over to fixed connectivity.
Build the temporary site from modular voice roles.
SWG-4032 supplies up to 32 approved cellular voice channels, UCP1202 provides the calling core and endpoint selection follows the site task.
Rapid does not mean unverified.
Coverage, operator policy and current endpoint capability remain project inputs.
Mobile voice channels
SWG-4032 provides documented GSM, WCDMA or LTE cellular voice access for the reference path.

Plan calling for your temporary site.
Share the site, duration, user count, call volume, cellular operators, endpoint types and longer-term transition. OpenVox can help define the gateway and calling-core roles.
