DECT bases and FXS adapters
DECT bases give you cordless handsets on the same extensions as everything else; FXS adapters connect analog devices (cordless phones, door intercoms, overhead paging) to the system.
Adding a device
Admin → Trunks → Add DECT / FXS opens the device wizard:
- Pick the model — templates cover the common DECT bases and FXS adapters: Yealink W-series bases (W52/W60B/W70B/W75B/W80B/W90B), Gigaset N-series (N510–N870), Snom M-series (M300–M900), Grandstream HT ATAs (HT801–HT818) and GXW42xx FXS gateways, Fanvil W710D, Patton and FarSouth FXS units.
- Name it and enter the MAC address (printed on the device label), plus any model-specific options the template exposes.
- Map handsets/ports to extensions — the wizard shows one row per account the model supports; assign each to an existing user, or leave ports unassigned.
Point the device's provisioning/config server at your system's provisioning URL (or use DHCP option 66 on the LAN) and it pulls a multi-account configuration: every mapped handset or port registers as its extension. The device list on the Trunks page carries edit, delete and Download Config (for devices you'd rather configure by file upload).
Changing the mapping later is the same wizard — save, and the device picks the new configuration up on its next provisioning fetch (reboot the base to force it).
Devices without a template
Any DECT base or FXS adapter that speaks standard SIP still works as a generic device: create one extension per handset/port, read its SIP credentials from Admin → Users → Auth Info, and register each account in the device's own web UI against your system FQDN (5060, or 5061 for TLS). You lose zero-touch provisioning, not functionality.
Fanvil W6xx portables
Fanvil's Wi-Fi/DECT portable handsets (W610W, W611W, W620W) are provisioned as regular Fanvil phones, not through the DECT/FXS flow — assign them like any desk phone.
