Contact center software with no per-minute platform fees

Stop paying the CCaaS markup on every minute. Licence the platform yearly, keep your SIP carrier, store recordings on your server. Cost model and pitfalls.

Two bills, one job

Telephony always has a carrier bill (DID + minutes). Cloud contact centers often add a second bill that scales with the same minutes or with AI processing.

Software you install on your server charges for capability (extensions, agents), not for how long customers talk.

Rough TCO thinking

Server or VM (own rack or rented VPS) — fixed monthly
SIP trunk — your negotiated rates
Wivoxa PBX — from about $3/extension/month billed yearly
Wivoxa Contact Center — agent licence covering queues, dialer and AI QC
Optional onboarding — one-off; free from 20 CC agents

Pitfalls to avoid

“Free PBX” that still needs a paid hosted trunk with opaque rates is not the same as bring-your-own-carrier. Confirm you can point the platform at Twilio, Telnyx, Vonage, Bandwidth or a local SIP provider.

Also confirm recording retention and AI stay on your disk — otherwise you reintroduce usage fees and egress risk.
