HOSTING COMPARISON — fill with your own evidence; no provider endorsement
Decision owner: Unknown
Review date: Unknown
Currency / tax treatment / comparison months: Unknown
Workload: peak simultaneous logged-in agents: Unknown; simultaneous calls/channels: Unknown; inbound/outbound mix: Unknown; minutes and destinations/month: Unknown; recording retention and storage: Unknown; support coverage/timezone: Unknown.
Named seats are not simultaneous agents or call capacity. Request comparable quotes from this same workload.

Mandatory requirements (record PASS / FAIL / UNKNOWN with source/date):
Maximum outage (RTO) and restore drill evidence: Unknown
Maximum acceptable data loss (RPO) and measured backup/restore evidence: Unknown
Required region and data handling: Unknown
Required integrations and export/exit rights: Unknown
Incident coverage and escalation: Unknown
FAIL excludes an option. UNKNOWN leaves selection unresolved. A cheap subtotal cannot override a failed mandatory requirement.

Cost worksheet: fill cost-template.csv; do not substitute zero for an unanswered quote item. Zero means explicitly included, no cost, or not applicable with explanation. Keep exclusions and sources beside each input.
Responsibility worksheet: fill responsibility-template.csv; every duty needs an owner and escalation path.

Worked fictional result: both options assume the same stated workload and pre-tax USD basis. Self-hosted 120 + 30 + 20 + (8*40) = 490/month; managed 480 + (2*40) = 560/month, with backup/monitoring included in the fictional 480. Add 180 carrier usage to each: 670 versus 740/month. Add one-time migration 300 versus 1200 over 12 months: 8340 versus 10080, difference 1740. These amounts are invented to demonstrate arithmetic, not quotes, benchmarks, recommended budgets, or observed service terms. Real workload/capacity and mandatory recovery evidence remain unverified, so the example makes no purchase recommendation.
