What you can do

VoIP & Telephony capabilities

Zero-touch phone provisioning

Discover handsets, push SIP config and firmware, and factory-reset a phone remotely. The demo shows a Grandstream GXP2170 onboarded with its firmware and provisioning state tracked.

Extensions and ring groups

Create extensions, assign them to ring groups, and manage them across one or many PBX systems.

Call routing

Configure trunks, DIDs, IVR menus, and queues so inbound calls land exactly where they should.

Voicemail and CDR

Manage voicemail boxes and review call-detail records for every call across the fleet.

Live call visibility

See active calls in real time and watch each device move through its lifecycle from discovered to managed to decommissioned.

Firmware compliance

Track handset firmware against a target and flag phones that drift out of compliance.

Good to know

Every device write rides the staged-change pipeline: changes are staged, then applied behind a dual gate with a full audit record and saga-style rollback. Nothing touches device config without double confirmation.
