Documented specifications
Fanvil · Fanvil retained the V64 in its live V Series catalogue and maintained product, document and firmware pages at review. Regional availability, hardware, firmware support and service-provider approval can change independently.
| Specification | Documented value |
|---|---|
| SIP identities | 12 SIP lines; configured identities are not proof of 12 simultaneous calls, 12 physical line keys or a measured call-start rate Source ↗ |
| Display | 3.5-inch 480 × 320 color LCD Source ↗ |
| Programmable keys | Up to 21 DSS assignments; the datasheet describes programmable Line, BLF and speed-dial roles, not 21 dedicated physical line buttons Source ↗ |
| Wired network | Dual Gigabit Ethernet ports with integrated PoE Source ↗ |
| Wireless | Built-in 2.4 GHz and 5 GHz Wi-Fi plus Bluetooth 4.2; installed WLAN, roaming and accessory acceptance remain separate Source ↗ |
| Power and mounting | PoE or external adapter; the user manual marks the adapter optional and wall-mount hardware as a separate purchase Source ↗ |
| Audio and conferencing | G.722 and Opus plus six-way local audio conference are published capabilities; negotiated media and conference behavior still depend on firmware, PBX and each call Source ↗ |
| Current firmware index | Fanvil listed V64-2.12.24.11 with a March 11, 2026 release date at review; the listing is not evidence of the installed or provider-approved build Source ↗ |
Unlisted fields remain unverified. Platform compatibility and remaining support life require confirmation for the exact ordered model.
Do not turn 12 lines into 12 simultaneous calls
Fanvil publishes 12 SIP lines for the V64 and up to 21 DSS assignments. Those figures describe configurable identities and paged programmable roles, not 12 physical line keys, 12 active media sessions or a measured calls-per-second result. The assigned account, extension, key page and PBX subscription remain separate objects.
Design the actual operator workflow: which lines, monitored users, queues, parks, pickups or speed dials must be visible at once, and which can live on another page. Preserve the final key map and retest it after provisioning and firmware changes.
Commission one network and power path at a time
The V64 datasheet lists dual Gigabit Ethernet with PoE and built-in dual-band Wi-Fi. The manual also describes an external-adapter path, marks the adapter optional and identifies separately purchased wall-mount hardware. Confirm the regional package and switch power budget instead of treating every possible path as included.
For wired service, retain switch port, VLAN, LLDP, DHCP, DNS, time and PoE evidence. For Wi-Fi, retain SSID, band, security, coverage and roam results. An association icon does not establish registration or intelligible two-way audio, and a UPS-backed switch does not protect a non-PoE local adapter.
Keep Bluetooth, USB and headset support exact
Bluetooth 4.2 and a USB port expand the possible accessory paths, while the datasheet names EHS cable arrangements for selected wireless headsets. None of those records approves an arbitrary headset, USB storage device, paired phone, recording workflow or data policy.
Record the exact accessory, cable, firmware and service behavior. Test answer, end, mute, volume, hold, transfer, reconnection and restart. Limit paired devices and removable media under organizational policy, and remove stale pairings or sensitive exports before reassignment.
Separate published media from negotiated media
The datasheet lists G.722 and Opus, HD voice and six-way local audio conferencing. These are capabilities, not evidence of the codec, packetization, DTMF, encryption, bridge ownership or audio quality on one call. Server-dependent call park, pickup, voicemail and recording labels likewise require compatible PBX behavior.
Capture the effective offer and answer, RTP endpoints and audible result for representative inbound, outbound, transfer and conference paths. Keep the phone's local conference resources distinct from a PBX or hosted conference service.
Track document, firmware and installed state independently
Fanvil's document library dates the V64 manual and datasheet set in 2024, while the firmware index listed V64-2.12.24.11 dated March 11, 2026. A newer listing does not prove that one phone is on that build, that a provider approved it or that upgrade prerequisites and rollback are satisfied.
Capture model label, hardware state, installed firmware, configuration backup, provisioning owner and approved target. Review release notes, stage a representative device, and verify configuration, registration, keys, accessories and calls after reboot before broad deployment.
Pilot identity, emergency use and recovery end to end
On an authorized service, test factory or clean provisioning, registration, inbound and outbound calls, caller identity, mute, hold, transfer, voicemail indication, BLF, pickup, conference, headset, speaker, restart, network loss, power loss and update recovery. Keep wired and Wi-Fi outcomes separate, and keep every server-dependent feature tied to the PBX evidence that supplies it.
Preserve the assigned number, physical location and provider-approved emergency validation process without an uncoordinated live emergency call. No V64, package, adapter, wall kit, switch, PoE path, WLAN, Bluetooth accessory, USB device, provisioning service, firmware, account, PBX, protected session, emergency route, availability, compatibility, price, audio result or live call was inspected or tested for this reference.
