Grandstream is one of the most versatile VoIP hardware manufacturers in the business. While brands like Cisco are closely associated with enterprise desk phones and Yealink has built its reputation on strong mid-range value, Grandstream has carved out a distinct identity through the breadth of its product range and its particular strength in categories that many competitors have not prioritized as deeply, including Android smart phones, hospitality devices, and carrier-grade provisioning for service providers.
Grandstream Networks was founded in 2002, headquartered in Boston, Massachusetts, with manufacturing operations in China. From early in its history, Grandstream positioned itself as a manufacturer of open-standards VoIP hardware targeting small and medium businesses, enterprises, and service providers. The company has steadily broadened its product portfolio to include not just desk phones but also video phones, conference phones, DECT systems, ATA adapters, IP PBX appliances, and network switches, making it one of the more complete VoIP ecosystem providers in the market.
The GXP series is Grandstream’s traditional business desk phone lineup, ranging from entry-level two-line models to high-end twelve-line executive phones with large color displays and BLF key support. The GXP1610 and GXP1615 cover basic entry-level needs. The GXP2130, GXP2135, and GXP2140 address mid-range requirements with progressively more lines, BLF keys, and display real estate. The GXP2160 and GXP2170 sit at the top of the GXP range, offering twelve lines, 24 to 48 digital BLF keys, and a 4.3-inch color display that makes them well suited to reception and operator roles.
The GRP series is Grandstream’s carrier-grade line, designed to meet the provisioning and reliability requirements of service providers and enterprise IT teams. ZERO-Config provisioning, which allows phones to be automatically configured when connected to the network, is a key feature of the GRP series and a reason many service providers recommend these models to their customers. The GRP range spans from basic two-line models through to the GRP2650 with fourteen lines and forty programmable keys, covering virtually every desk phone use case within a carrier-friendly framework.
This is where Grandstream genuinely differentiates itself from most competitors. The GXV series of Android-based video phones brings a smart device experience to the desk, running full Android and supporting a range of business applications alongside voice and video calling. The GXV3350 features a 5-inch touchscreen, the GXV3370 and GXV3450 offer 7-inch displays with different orientation options, and the GXV3480 sits at the top with an 8-inch touchscreen and the most comprehensive feature set in the lineup.
For executives and senior staff who want to consolidate communication tools into a single desk device without the limitations of a standard phone’s interface, the GXV series offers something most competitors do not. Running Android means these phones can support third-party business applications, video conferencing apps, and custom enterprise software alongside standard SIP calling.
Grandstream’s GHP hospitality series is one of the most comprehensive dedicated hotel phone lineups from a single manufacturer. The range includes compact models like the GHP610 and GHP611, full-sized desktop models like the GHP620 and GHP621, and color LCD models like the GHP630 and GHP631. Most models are available in both white and black finishes, and several include built-in Wi-Fi for cable-free installation. The GHP630W with dual-band Wi-Fi 6 represents the most forward-looking option in the hospitality lineup.
For hotel operators, the GHP series provides a coherent family of room phones that can be mixed across different room categories while maintaining a consistent aesthetic and management approach.
Grandstream’s GAC2500 and GAC2570 conference phones bring Android-based smart functionality to the conference room, offering touchscreen interfaces, Wi-Fi, Bluetooth, and 360-degree microphone coverage. The DECT range, built around the DP750, DP752, and DP755 base stations paired with DP7xx series handsets, covers single-cell through high-density enterprise DECT deployments. The ruggedized DP735 handset is among the most capable ruggedized DECT options available from any manufacturer.
Grandstream is the strongest choice for organizations that need Android-based smart phones with application support, hotel operators equipping guest rooms with the GHP hospitality series, service providers who value ZERO-Config provisioning and carrier-grade reliability, and businesses that need a broad, versatile product family that covers everything from entry-level desk phones to video conferencing hardware under a single brand relationship. Its combination of breadth and competitive pricing makes it one of the most versatile choices in the business VoIP phone market.
