Rugged DECT system for 10 handsets

The Yealink W77P is a SIP cordless phone kit that supports up to 10 W57R handsets and 10 SIP accounts. It handles up to 20 simultaneous calls across the system, with two concurrent calls per handset. The base station connects via a single 10/100M RJ45 port and accepts Power over Ethernet Class 1 or the supplied AC adapter.

Check DECT coverage and SIP readiness

Verify that the 50-metre indoor and 300-metre outdoor radio range suits the building layout before ordering. Each handset requires a DECT registration slot on the base, and the network must carry SIP v1 or v2 traffic with VLAN tagging, LLDP or 802.1x if those features are used. Ensure the PoE switch or injector can deliver IEEE 802.3af Class 1 power to the base station.

Battery life under continuous use

A handset battery rated at 1460 mAh and 5.4 Wh provides up to 40 hours of talk time and 575 hours of standby in ideal conditions. Quick charging restores two hours of talk time after only ten minutes on the wall-mountable charger. TLS and SRTP encryption run continuously without reducing the stated battery endurance.

Questions about this item

Does the W77P kit include the handset and base station, or must I buy the W57R handset separately?

The W77P is an IP DECT phone kit that includes one W57R handset and the base station; up to 10 handsets can be registered to the same base.

Should I choose a single handset or add more W57R units for a team of eight?

One base supports up to 10 handsets and 10 SIP accounts, so eight handsets can share the same system without extra base stations.

How long will a fully charged W57R handset last during a normal workday of calls?

The 1460 mAh battery delivers up to 40 hours of talk time and 575 hours of standby; a 10-minute charge adds roughly 2 hours of talk time.
