Collection: Cordless VoIP Phones

DECT cordless SIP phones from Fanvil, Yealink, and Grandstream for offices, clinics, and retail environments where staff move while on calls. DECT operates on the dedicated 1.9 GHz band — separate from your 2.4/5 GHz Wi-Fi, with no interference or dependency on Wi-Fi signal quality. Indoor range is typically 50 meters; open-air up to 300 meters. Multi-handset systems allow multiple handsets to share one SIP extension — all ring simultaneously, any can answer or transfer. DECT vs. Wi-Fi SIP phones: DECT is simpler and more reliable for voice in most offices. Wi-Fi SIP phones suit facilities with enterprise-grade Wi-Fi roaming already deployed. Net-30 terms available.

Frequently Asked Questions

DECT is a dedicated radio standard for cordless phones operating at 1.9 GHz — a frequency band reserved for voice and separate from Wi-Fi. It uses TDMA (time-division multiple access) to ensure low-latency, interference-free voice quality. Wi-Fi SIP phones share the 2.4/5 GHz band with all other Wi-Fi traffic, which can introduce jitter and degraded voice quality in congested network environments.

Most consumer and SMB DECT systems support 4–8 registered handsets per base station; enterprise multi-cell systems support more. All handsets share the same SIP extension and ring simultaneously on incoming calls. Note the maximum simultaneous active calls spec — many base stations support 2–4 concurrent calls even if 6+ handsets are registered.

Yes — DECT repeaters extend a single base station's coverage without additional SIP registrations. For large facilities requiring seamless roaming, enterprise multi-cell DECT systems (Yealink W80B, Snom M700) use multiple coordinated base stations — handsets hand off between bases mid-call without dropping, similar to cellular roaming.

Enter SIP server, SIP username, and password from your cloud PBX admin panel into the DECT base station's web configuration UI. Unlike Teams-certified phones, DECT phones don't support auto-provisioning from most cloud PBX portals and require manual SIP configuration.

Battery life varies by model but is typically 8–12 hours of talk time and 80–200 hours standby. Handsets charge in their cradles between calls. For multi-shift operations, consider purchasing spare batteries or additional charging cradles to ensure handset availability across shifts without downtime.
