AT&T 4-Handset DECT 6.0 Cordless System
This model supports conference calls between an outside line and up to four cordless handsets, plus intercom between handsets and the base. It features a 5″ color base display for easy menu navigation and personalized one-touch shortcuts for quickly accessing contacts, messages, and call history. It’s best for small teams that want clear, centralized control from a single base unit. A potential limitation is that adding more than four handsets requires a separate plan or gear, so plan accordingly.
AT&T 5-Handset DECT 6.0 Cordless System
Designed for growing teams, this 5-handset system builds on the 4-handset model with an extra handset for additional offices or departments. The 5″ color base display and one-touch shortcuts help staff access calls, messages, or history quickly. It offers strong conference and intercom capabilities, enabling efficient collaboration across multiple users. Best for mid-size offices needing extra reach without complexity. A caveat is that the more handsets, the more you’ll want to manage battery life and charging schedules for all devices.
VTech DS6151-2 2-Line Expandable
This two-line system is ideal for small offices that need to separate work areas or departments while maintaining centralized management. It supports expansion up to 12 handsets and provides DECT 6.0 security for clear calls, with interference-free operation. It is best for budget-conscious teams that still require reliable multi-line functionality. A limitation is that two lines may not be sufficient for heavier call volumes during peak times.
Panasonic KX-TG9582B 2-Line System
Panasonic’s system combines several advanced features, including Link2Cell Bluetooth to connect smartphones for cellular calls, a 3-way conference feature, and DECT 6.0 for clean, reliable audio. It’s well-suited for offices that rely on both landline and mobile calls and want to unify them under one system. Choose this if you need seamless smartphone integration and extended conferencing. The trade-off is that Bluetooth pairing can require extra setup and management for multiple devices.
VTech DS6151-11 DECT 6.0 2-Line + 3 DS6101-11
This configuration adds three extra handsets (DS6101-11) to the DS6151-11 base, expanding capabilities across a small business. It supports two-line operation with additional handsets for a broader workspace. It’s best for teams that need more mobility across multiple rooms without installing new lines. A limitation to note is physical desk space and charging needs for multiple handsets in shared environments.
VTech Small Business System 80-0328-00
Ideal for four-line offices seeking scalable growth, this system supports conference calls with multiple participants and is compatible with up to four lines for expanded calling. The model focuses on professional call handling and simple expansion as your business scales. Best for teams needing a straightforward path to multi-line management with minimal setup.
AT&T 2-Handset DECT 6.0 System
This compact two-handset option provides essential features like a 5″ color base display, one-touch shortcuts, conference calling, and intercom between handsets and the base. It’s best for solo operators or small offices with limited space. The benefit is easy setup and straightforward daily use, with the trade-off of fewer handsets and lines for larger teams.
