Insights

The Grandstream DP750 is built for organisations that need cordless VoIP mobility without compromising on call quality or system flexibility. As the base station of Grandstream’s DECT lineup, it acts as the hub that connects compatible handsets, such as the DP720 and DP735, to your SIP infrastructure.

Its ability to manage up to 10 SIP accounts across 5 handsets makes it a practical choice for small offices, reception desks, and retail counters where several staff members need to share access to multiple lines. The shared SIP account feature means any handset can pick up an incoming call, so nothing gets missed simply because a colleague has stepped away from their desk.

Combined with integrated PoE, automated provisioning, and strong encryption, the DP750 is also straightforward to deploy and manage at scale, particularly when paired with a Grandstream UCM IP PBX for Zero Config setup.

Key Features

Long-Range DECT Coverage

The DP750 provides up to 50 metres of indoor range and up to 300 metres outdoors, giving registered handsets the freedom to roam across larger offices, warehouses, and outdoor spaces while staying connected.

Up to 10 SIP Accounts and 5 Handsets

The base station supports up to 10 SIP accounts per system and up to 5 registered DECT handsets, with each handset able to be mapped to the required accounts and up to 10 lines.

Full HD Audio

Calls made through the DP750 benefit from full HD audio, delivering clearer, more natural-sounding conversations across every paired handset.

5 Concurrent Calls

The system supports up to 5 concurrent calls, allowing multiple staff members to be on active calls at the same time without conflict.

3-Way Audio Conferencing

Built-in 3-way voice conferencing lets users bring an additional participant into a call directly from the handset, without needing separate conferencing hardware.

Integrated PoE

Integrated Power over Ethernet simplifies installation, allowing the base station to be powered and networked through a single cable when connected to compatible PoE switches or injectors.

Flexible Ring Groups

The DP750 supports Circular, Linear, Parallel, and Shared ring group modes, giving administrators control over how incoming calls are distributed across registered handsets.

Automated Provisioning

Support for TR-069 and XML configuration files streamlines deployment, while Zero Config provisioning is available when used with a compatible Grandstream UCM IP PBX.

Security and Encryption

TLS, SRTP, and HTTPS encryption, along with DECT authentication, help protect calls, credentials, and account information from unauthorised access.

Large Phonebook Capacity

A downloadable XML and LDAP phonebook supports up to 3,000 entries, making it easy to manage contacts across a shared handset fleet.

Server Redundancy

Built-in server redundancy and failover help maintain call continuity in the event of a primary server disruption.

Use Cases

• Small Offices: Equip a handful of staff with cordless VoIP handsets sharing a common set of SIP lines.
• Reception Desks: Use shared SIP accounts so any available handset can pick up incoming calls.
• Retail Stores: Give sales staff cordless mobility to answer calls or coordinate from anywhere on the shop floor.
• Hospitality: Keep front-desk and service teams reachable as they move across a property.
• Warehouses: Extend cordless VoIP coverage across larger indoor and outdoor areas.
• Residential VoIP: Set up a home cordless phone system with multiple handsets and shared lines.
• Multi-Site Deployments: Use automated provisioning and Zero Config to roll out consistent configurations across several base stations.

Is It Right?

This base station is a great choice if you:

• Need to deploy multiple cordless DECT handsets from a single base station.
• Want shared SIP accounts so any handset can answer incoming calls.
• Require long-range indoor or outdoor DECT coverage.
• Want HD audio and 3-way conferencing for clearer team calls.
• Prefer simplified installation with integrated PoE.
• Need automated provisioning for multi-site or multi-device rollouts.
• Plan to pair the base station with Grandstream DP720 or DP735 handsets.

You may want to consider another option if you:

• Only need a single cordless handset without multi-user sharing.
• Prefer a standalone desk phone that doesn’t require a base station.
• Need a ruggedized, IP-rated handset for harsh environments (consider the DP735 handset instead).
• Require more than 5 concurrent calls or 10 SIP accounts (consider the DP755 base station instead).
