VoIP Phones for a 10-Person Office (Without the Headaches)

Ditch the copper lines — number porting, QoS, and headset picks for a clean cutover weekend.

  1. 1. Audit lines and pick the platform

    Count real concurrent calls (not phones) — 10 staff often need 4–6 channels. RingCentral, Nextiva, and Teams Phone all work; pick by must-haves (fax? overhead paging? call queues?) not marketing.

  2. 2. Fix the network before porting numbers

    VoIP needs stable upload and QoS rules prioritizing voice. Test a week on the new platform with temporary numbers first — porting day is irreversible, so prove call quality beforehand.

  3. 3. Port over a weekend with a rollback plan

    Submit ports 2+ weeks ahead, cut over Friday evening, test every extension Monday 8am with the old system on standby. Keep one analog line for alarms and elevators — they don't VoIP.

Guide FAQ

$20–$35/user/month plus handsets ($100–$200 each) or softphones (free). Most 10-person offices land well under old copper bills.
About 0.1 Mbps per concurrent call — trivial bandwidth. Stability and QoS matter 100x more than speed; that's the part people skip.
