SIP compatibility
Works with SIP devices: IP phones, gateways, doorbells, and paging systems.
SIP (Session Initiation Protocol) is the open standard that modern business phones use to make and receive calls. Because Voxbi is built on SIP, any device or system that speaks the same protocol can connect to it without requiring proprietary hardware or a locked-in vendor relationship. Desk phones, software-based phones, VoIP gateways, DECT base stations, door intercoms, and paging systems all qualify, provided they implement the SIP standard.
This matters in practice because it means you are not forced to replace working hardware when you move to Voxbi, and you are not tied to a single hardware brand for future purchases. Devices are added in the Voxbi Cockpit by registering their MAC address, and compatible models can be provisioned automatically so the phone configures itself when it connects to the network.
When you'd use SIP compatibility
An organisation that already owns a fleet of SIP desk phones and wants to move its phone system to the cloud without buying new hardware. Register the existing phones in the Voxbi Cockpit and they connect to the cloud PBX over the network.
A building that has a SIP-compatible door intercom or entry system. The device registers with Voxbi the same way a desk phone does, so calls from the door ring to a reception extension or a designated group.
A team that works across devices: desk phones at the office, the Voxbi softphone app on a laptop or mobile, and a web browser for occasional calls. All three connect over SIP and ring together or separately depending on how twinning and call preferences are configured.
