Cisco 6871
Bolt-in to LightningArrows Voice · Already multiplatform (3PCC) — no conversion license

Old and surplus Cisco 6871 handsets can get a real second life on multiplatform SIP — same Desk Voice path as our 8851 demo ($0.25/day class pricing).

Cisco 6871 on LightningArrows Voice

Engage. Execute. Deploy. — reuse good hardware instead of buying throwaway softphone-only setups.

This page mirrors our 8851 demo path for the 6871. Official convertibility for 78xx/88xx comes from Cisco’s Enterprise↔MPP guide (eligible device tables).

Hardware

Field Value
Series 6800
Enterprise PID (used CUCM sets) — (native MPP only)
Multiplatform PID CP-6871-3PCC-K9=
Firmware family sip68xx MPP loads
Typical lines / keys ~6 (varies by KEM / config)
Role Desk phone on Ethernet (PoE or brick)
Conversion license Native MPP — no E2M license

Native MPP color display set. Third-party SIP ready when on MPP firmware.

Why MPP/3PCC? Enterprise firmware is built for CUCM. Multiplatform firmware speaks standard SIP, so it can register to LightningArrows Voice (Asterisk-class PBX) or other ITSPs.

How to tell what you have

  1. Flip the phone — read the PID on the sticker.
  2. …-3PCC-K9 / 3PC / 3PW → already multiplatform.
  3. …-K9 without 3PCC → enterprise → convert before LA Voice.
  4. On the set: Information and settings ≈ MPP; Applications ≈ often enterprise.

Network (same pattern as 8851)

Field Suggested
Port Network/SW (PoE switch or injector / brick)
IP Static or DHCP reservation
DNS Required (router + optional 8.8.8.8) — blank DNS breaks license fetch and SIP
Web UI https://PHONE_IP on the same LAN

Optional: PC/Mac in the PC pass-through port on many desk models.

Path to dial tone

[1] Network OK (IP + DNS)
[2] MPP firmware (native 3PCC or E2M convert)
[3] Order Desk Voice / Office Voice
[4] Ext 1 SIP or Profile Rule URL
[5] Status = Registered
[6] e911 address before real outbound
[7] DID optional

Conversion license

Not required. 6800 multiplatform phones are ordered/used as 3PCC/MPP. They do not flip from CUCM enterprise firmware via L-CP-E2M-*.

If the set is somehow still not speaking standard SIP, confirm Product Name shows 3PCC and load current MPP firmware from Cisco.

Consumer checklist

  • Confirm model 6871 and PID (enterprise vs 3PCC)
  • Phone has LAN IP + DNS
  • Web UI opens
  • MAC recorded (sticker / status)
  • MPP ready (convert if needed)
  • Desk Voice ordered
  • Ext 1 or provision URL set
  • Registered
  • e911 collected

Ext 1 fields (MPP web UI)

These are SIP / PBX values from your welcome email — not the marketing website URL.

Field What to enter
Proxy / Outbound proxy YOUR_PBX_HOST — SIP registrar hostname or IP we issue (example shape only: sip.example.com or a public IP). Do not put https://… or a /grav web path here.
User ID / Auth ID Your seat / extension ID
Password Your SIP password
Display name Optional label on the phone
Profile Rule (optional) HTTPS provision URL we issue (downloads phone.xml). This is HTTP(S) config, separate from the SIP proxy host.

Save → reboot if asked → Status / Line = Registered.
