Small business VoIP FAQ
Most SMBs pay ~$10–$30 per user/month for hosted/cloud VoIP if they use softphones; desk phones add about $80+ per phone one‑time; on‑prem PBX can run $10k+ up‑front. Expect extras like number porting ($5–$15/number) and E911 fees (~$1.50–$3 per user/month). Net result: VoIP remains the most cost‑effective path vs. legacy phone systems.
Yes - if you size bandwidth correctly and configure QoS. Use ~85–100 Kbps per concurrent G.711 call (toll‑quality), or ~30–35 Kbps with G.729 to save bandwidth. Prioritize voice packets (DSCP EF 46) and keep latency <150 ms, jitter <30 ms, packet loss <1%.
Independent roundups consistently highlight RingCentral RingEX, Intermedia Unite, Zoom Phone, Vonage, 8x8, Dialpad, etc. Your “best” pick depends on priorities: all‑in‑one UC, lowest cost, CRM/AI features, or international calling.
Hosted/Cloud PBX = provider runs the phone system in the cloud (no on‑site PBX), fastest to deploy, predictable per‑user pricing. SIP Trunking = keep your on‑prem PBX, replace copper lines with internet “trunks”—more control if you already own PBX gear, but you manage more pieces
Yes. U.S. rules require carriers to allow number portability. Typical wireline/VoIP ports take ~5 - 10 business days (wireless can be faster). Accuracy of paperwork (billing name/address, account #, LOA) is the #1 factor affecting timelines.
If you operate a multi‑line telephone system (MLTS), your solution must support direct 911 dialing (no “9” prefix), 911 call notifications, and deliver a dispatchable location (street address + suite/room) to PSAPs - requirements phased in 2020 - 2022 and enforced by the FCC. Most SMB VoIP platforms include tools to help, but you must configure them correctly.
VoIP = voice only (mostly). UCaaS = voice + video + messaging + integrations in one platform. Many SMBs consolidate to UCaaS to reduce app sprawl and gain AI/analytics, while keeping costs near basic VoIP - especially if they’re already on Microsoft 365 (Teams Phone supports Calling Plans, Operator Connect, and Direct Routing).
