Move between work areas
Use a supported SIP or software endpoint within the business calling environment.
Keep extensions reachable beyond the desk.
Enable business extensions to be reached throughout the company and remotely, while retaining a consistent extension identity and call policy as users move between approved endpoints.
The desk phone limitation
Let work patterns guide each extension.
Employees may need to manage business calls from desk phones, software clients, or another supported SIP endpoint.
The design must preserve extension identity, routing, and permissions while confirming the current client, device, and network capabilities required for each user group.
Connect an approved remote client
Extend the business extension over the network and security design selected for the project.
Keep existing phones in service
Allow documented analog, SIP, and software endpoint types to communicate.
Apply calling permissions
Keep external routes, transfer, and dialing rules under UCP control.
The extension stays on the platform while the endpoint changes
Extension identity
The extension stays on the platform while the endpoint changes
UCP manages the extension and call behavior, while connected SIP phones, SoftPhone, or desktop clients come from the authorized network environment.
Desk endpoint
Validated SIP or analog phone
Software client
Current approved client capability
UCP extension
Identity, routing, and permissions
SIP trunk
External or inter-system call path
Keep the platform stable as endpoints vary.
UCP is the call core; endpoint and gateway selection follows approved user and device requirements.
Verified extension model for mobile work.
Current client versions, operating systems, remote access, and feature availability remain project checks.
Multiple endpoint categories
UCP documents analog phones, SoftPhone, SIP phones, desktop clients, SIP consoles, and IADs.
Business calling features
UCP documents hold, transfer, forwarding, pickup, conference, and voicemail services.
Number and permission control
Number analysis and permission features remain part of the UCP call core.
External interoperability
Standard SIP trunks connect UCP with documented IP voice environments.
Design extensions around user mobility.
Share user groups, endpoint preferences, current client requirements, network access, and calling policies. OpenVox can help define the platform and validation scope.
