Documented specifications
Grandstream · Current manufacturer catalogue, product, documentation and firmware-table evidence at review; regional inventory, price, certification and future support end date were not confirmed
| Specification | Documented value |
|---|---|
| Exact variant | Black wired-only GHP631; GHP630 is white and wired-only, while GHP630W and GHP631W add Wi-Fi 6 Source ↗ |
| SIP accounts and lines | 2 SIP accounts and 2 lines; these do not establish simultaneous-call or call-start capacity Source ↗ |
| Display and keys | 3.5-inch 480 × 320 color LCD, 6 context-sensitive soft keys and 10 configurable digit-key speed dials Source ↗ |
| Network | One auto-negotiating 10/100 Ethernet port; Wi-Fi 6 belongs only to W variants Source ↗ |
| Power | Integrated IEEE PoE Class 2; family documentation does not list the W-variant adapter package for this wired-only model Source ↗ |
| External charging | USB Type-C output for external-device charging up to 500 mA, not documented here as a host or data interface Source ↗ |
| Management and protection | GDMS, TR-069, HTTPS or encrypted file provisioning, TLS, SRTP, 802.1X and secure boot are documented capabilities, not deployed results Source ↗ |
| Conference feature | Documentation conflict: product and datasheet advertise 3-way conference, while the family FAQ says GHP63x does not support conference Source ↗ |
Unlisted fields remain unverified. Platform compatibility and remaining support life require confirmation for the exact ordered model.
Keep the black wired-only model exact
The GHP631 is the black non-W model. The white GHP630 shares its wired-only boundary, while GHP630W and GHP631W add Wi-Fi 6 and a local-adapter path. Do not order or commission from color or family name alone. Preserve the chassis label, regional package, hardware revision, firmware, room, extension, PBX and provisioning owner.
The absence of a W suffix means Wi-Fi and the W-variant adapter package are not established for this SKU. The phone's network and power acceptance therefore starts with its single 10/100 Ethernet link and PoE Class 2 requirement.
Commission the room jack and PoE together
Validate cable, room jack, patching, switch port, VLAN, DHCP, DNS, time, SIP registration and RTP as separate states. Include phone demand and the optional external-device charging load in the switch's port and total PoE budget, then observe restart and call behavior when that load changes.
The USB-C connector is documented as a charging output up to 500 mA; it is not evidence of headset, storage, network or management data. Record switch and upstream backup power instead of assuming the old analog line's failure behavior survived migration.
Map display and service keys to policy
The family datasheet lists a 3.5-inch color display, six context-sensitive soft keys and ten configurable digit-key speed dials. Translate each label into an approved front-desk, service, room-to-room, restricted external or emergency route and test its actual result.
Two SIP accounts and two lines are configured identities and appearances. They do not establish simultaneous-call capacity, a property integration or any dial-plan behavior.
Preserve the family conference conflict
Grandstream's product page and datasheet advertise three-way conference, while the current family FAQ says the GHP63x exception does not support call conference. Do not silently prefer the datasheet. Test the exact firmware and PBX workflow or exclude conference until the manufacturer resolves the documentation.
Likewise, codec and packet-loss-tolerance statements are capabilities and manufacturer claims, not installed audio evidence. Retain negotiated SDP, path measurements and listening acceptance for the actual room.
Accept provisioning, turnover and failure behavior
Choose one authoritative management path and verify configuration download, application, reboot, registration and call separately. Secure boot, encrypted configuration, TLS, SRTP and 802.1X require active-state evidence. Clear occupant data, confirm room identity and service keys, and recheck emergency location after every swap.
No GHP631, package, Ethernet path, PoE path, USB load, display, key, PBX, provisioning path, protected session, emergency route, firmware, price, availability, compatibility, audio, conference or call was inspected or tested for this reference.
