Webex Calling FAQ
Most SMB VoIP plans fall between $10–$35 per user/month (U.S.), with higher tiers unlocking analytics, recording, and advanced routing. True cost depends on billing term (annual vs. monthly), add ons (SMS, toll-free minutes, compliance), international calling, and hardware.
Must have core: auto attendant/IVR, call queues, number porting, voicemail to email/transcription, call recording/monitoring, analytics, mobile/desktop apps, integrations (CRM, productivity suites), and SMS/MMS.
Reliability benchmarks: Top providers advertise 99.999% uptime SLAs and global infrastructure; call quality relies on stable bandwidth, low jitter (<30 ms), packet loss (<1%), and QoS prioritization on your LAN/WAN. Providers also offer power/Internet outage failover (e.g., call forwarding to mobile).
Hosted VoIP (cloud PBX): Provider hosts the PBX; minimal on prem hardware; easy to scale; subscription per user; best for teams without dedicated telephony IT. [getvoip.com] SIP trunking: Connects an existing on prem PBX to the Internet; keeps legacy investments while adding VoIP features; better if you already own PBX gear and have IT staff. [siptrunk.com], [sip.us] Key differences: Hosted VoIP is fully managed and voice first; SIP adds flexible integration and can carry voice, messaging, video over existing PBX paths. Many markets are phasing out PSTN by ~2030, accelerating cloud migrations.
Security reality: VoIP traverses IP networks; without safeguards it’s exposed to eavesdropping, toll fraud, DDoS, spoofing, AI voice cloning social engineering. Encrypt signaling/media (TLS/SRTP), harden endpoints, segment voice VLANs, use MFA, and monitor for anomalies.
What to know: Interconnected VoIP providers must offer E911, but you must register and keep your physical location updated, especially for nomadic use. During power or Internet outages, VoIP may not work; plan battery backup and mobile failover.
Zoom Phone - low starting price, tight Zoom Workplace integration, AI post call summaries; add-ons for analytics/international can raise total cost. Google Voice - simple admin, auto attendants, ring groups; clear tiered pricing and strong Workspace fit; check country availability and Premier features for larger orgs.
