Frequently Asked Questions
Common Questions About Wi-Fi Cordless Phones
Will Grandstream WP phones work with my existing phone system?
Yes. All WP Series handsets are SIP-compatible, which means they work with any standard cloud or on-premise phone system — including BizTel, iPECS Cloud, Avaya, 3CX, and most modern PBX platforms. Pair them with your existing system — no replacement required.
Which model is right for my workplace?
Depends on the environment. WP810/WP816 for offices wanting affordable Wi-Fi cordless. WP820/WP822 for enterprise-grade indoor mobility. WP825/WP836 for rugged industrial use (warehouses, factories). WP826 for the best balance of features, battery, and price. WP856 for premium deployments needing Android, touchscreen, and barcode scanning.
Do I need special infrastructure to deploy these phones?
No proprietary base stations required. The WP Series connects directly to your existing Wi-Fi network. For best performance across large facilities, we recommend modern Wi-Fi access points with 802.11k/r/v fast roaming support. Comstel can review your network and recommend access points if needed.
What does "seamless roaming" actually mean?
When a user moves between Wi-Fi access points (e.g. walking from the front office to the warehouse), the WP handset switches access points without dropping the call. This requires both fast-roaming-capable handsets (most WP models support 802.11k/r/v) and Wi-Fi access points that also support these standards.
What's the difference between IP67 and IP65?
IP67 (WP825, WP836) means dust-tight and waterproof up to 1m for 30 minutes. IP65 (WP856) means dust-tight and protected against water jets from any direction. Both are excellent for industrial environments. IP67 is preferred for the harshest conditions (warehouses, factories with heavy water exposure).
Can the WP856 really replace a smartphone for warehouse staff?
For workplace use, yes. The WP856 runs Android 13 with Google Play, has a 5.5" HD touchscreen, built-in 1D/2D barcode scanner, NFC, and 20-hour battery. Warehouse and logistics teams use it as a single device for calls, scanning, picking apps, and inventory management — replacing a phone, scanner, and tablet.
How do I manage a large fleet of WP handsets?
Through Grandstream Device Management System (GDMS) — a free cloud platform for centralised provisioning, configuration, firmware upgrades, and monitoring across all your handsets. Comstel can set up GDMS for you so you manage your entire fleet from one interface.
How do I order?
