Product description

Grandstream DP755 – VoIP DECT Base Station for Flexible and Secure Business Telephony

The Grandstream DP755 VoIP DECT base station provides reliable wireless voice communication for businesses, offices and larger workplaces. It connects compatible Grandstream DECT handsets to IP telephony systems, helping employees stay reachable as they move around throughout their working day.

Supporting up to 10 DECT handsets, 20 SIP accounts and 20 lines per handset, the base station provides a flexible infrastructure for business telephony installations. Shared SIP accounts allow multiple employees to answer incoming calls using different handsets.

Extended DECT range for greater freedom of movement

The DP755 allows employees to move freely within the supported DECT coverage area while on a call. With a range of up to 50 metres indoors and 400 metres outdoors, the base station is suitable for offices, retail environments and large business premises.

The maximum outdoor range depends on the handset being used. With the Grandstream DP730, coverage can reach up to 400 metres, while the DP722 and DP720 support distances of up to 350 metres. Actual coverage depends on the building layout and surrounding environment.

Manage up to 10 handsets and 20 SIP accounts

Support for up to 10 DECT handsets makes it possible to create a shared telephone system for multiple employees. Up to 20 different SIP accounts can be configured in total, with each handset supporting up to 20 SIP accounts.

A single SIP account can be assigned to several handsets, allowing teams to handle incoming calls together without being tied to a fixed desk. This flexible account assignment is particularly useful for departments that share telephone numbers.

HD audio and professional telephony features

The Grandstream DP755 supports HD audio for clear voice communication and full-duplex hands-free calling with compatible handsets. A range of audio codecs, including G.722 and OPUS, provides flexibility across different VoIP environments.

For everyday business communications, features such as call forwarding, call transfer, call hold, Do Not Disturb and message waiting indication are available. Three-way audio conferencing is also supported, allowing several participants to join the same conversation easily.

With Push-to-Talk functionality, compatible handsets can also be used for direct communication between colleagues. This is particularly useful when quick discussions are needed without making a conventional telephone call.

DECT encryption for secure conversations

The DP755 uses DECT authentication and encryption technologies to protect wireless communications and associated accounts. These features provide essential security for professional voice communications.

Built-in protection mechanisms help maintain secure wireless telephony and reduce the risk of unauthorised access to DECT communications.

Centralised management and automated configuration

The Grandstream Device Management System (GDMS) enables compatible Grandstream devices to be deployed, configured, monitored and managed centrally. This cloud-based platform helps businesses and IT administrators manage both individual devices and large-scale installations.

The DP755 also supports TR-069 and XML configuration files for automated provisioning. When used with Grandstream UCM series IP PBX systems, it offers Zero Config functionality, simplifying the setup and management of the telephony environment.

Through GDMS, administrators can manage device configurations, update firmware and monitor device status. This makes it easier to maintain communication systems deployed across multiple sites.

Applications and compatibility

The Grandstream DP755 is suitable for business offices, retail stores, large operational areas and extensive premises where employees need to remain reachable while moving around. The base station is also suitable for campuses and other outdoor environments with adequate DECT coverage.

The base station works with compatible Grandstream DECT handsets. The manufacturer's website specifically references the DP730, DP722 and DP720 models, as well as pairing with the DP725. Available features and coverage distances depend on the handset used.

For businesses using Grandstream UCM IP PBX systems, the DP755 offers additional benefits through automated deployment. Centralised management via GDMS also makes it a practical option for installations involving multiple devices and locations.
