Stop paying blind audit surcharges
Signing a managed service provider (MSP) contract for a cloud voice assessment without understanding exact labor rates is a fast track to budget overruns.
MSPs frequently bundle generic network discovery scans with hidden surcharges for deep packet inspection and SIP protocol checks.
If you do not lock down the scope beforehand, standard readiness audits easily balloon from a flat retainer into unexpected hourly change orders.
Understanding how MSPs structure their assessment pricing, where billable scope creeps, and how to verify real readiness data prevents costly surprises during your cloud PBX migration.

Key Takeaways & Quick Links
- Flat-Fee vs. Hourly Blends: Most regional MSPs charge between $1,500 and $4,500 for a baseline pre-VoIP network assessment depending on site count.
- Packet Capture Add-ons: Watch out for add-on fees billed separately for sustained 48-hour jitter and MOS score logging.
- LAN Switch Readiness: Assessments that omit Power over Ethernet (PoE) budget checks leave you exposed to unexpected internal switch upgrade costs later.
The short answer ⚡
A thorough pre-VoIP network assessment performed by a qualified MSP typically runs as a one-time project fee:
- Small office <50 users: $1,500 and $4,000
- Multi-site: $5,000 to $12,000+.
To protect your budget, ensure the Statement of Work (SOW) explicitly covers three things:
- Deep packet inspection (DPI)
- 48-hour packet capture testing for jitter & packet loss
- Inventory of existing LAN switches for PoE budgeting.
Never approve open-ended hourly billing for network readiness discovery.
Healthcare scenario: A clinic’s $4,200 switch replacement
A pediatric therapy practice with 3 locations hired an MSP for a $2,500 pre-VoIP readiness audit before migrating to a cloud phone system.
The MSP reported that internet speeds were sufficient, but failed to audit switch PoE capacities.
When 45 new IP desk phones arrived, half would not power on. The legacy switches lacked PoE+ output.
This triggered an unexpected $4,200 switch replacement order and delayed the deployment by two weeks.
To avoid deployment friction, they should have mandated a complete inventory of edge routers, PoE switches, and UPS units alongside WAN latency tests.
MSP assessment fee matrix
The following table outlines standard project fees and line-item billing structures charged by MSPs for pre-cloud VoIP network audits:
| Tier | Size | Fee Range | Scope |
|---|---|---|---|
| Basic Port & Ping Scan | 1 site (< 25 seats) | $750 – $1,500 | Basic bandwidth speed test & firewall port check |
| Standard Voice Audit | 1-2 sites (25 – 100 seats) | $2,000 – $4,500 | 48-hour packet capture, jitter/MOS analysis & router config audit |
| Multi-Site business | 3 to 10 Sites (100 – 500 seats) | $5,000 – $12,000+ | SD-WAN review, QoS policy mapping & PoE switch inventory |
| Advanced Security Add-on | Multi-site / High-compliance | $3,500 – $7,500 add-on | Firewall SIP ALG audit, RTP port mapping & TLS check |
💡 Derek’s Pro Tip: Flat-fee quotes under $1,000 usually mean the MSP is running a basic automated ping test. These low-cost scans miss internal buffer bloat and packet fragmentation entirely.
The hidden scope expansion trap
Many service providers use low-cost assessments as a loss leader to upsell expensive monthly managed services.
- Low-cost retainer hook: An MSP offers an initial $500 evaluation to win your business. During the audit, they flag minor cabling or firewall firmware items.
- How billing escalates: Instead of providing a flat remediation estimate, they classify these findings as critical blockers, moving the engagement to hourly rates ($175–$250/hr).
💡 Derek’s Pro Tip: Demand a strict Statement of Work (SOW) capping billable discovery hours and requiring written approval before any remediation begins.
Auditing bandwidth and QoS line items
A true voice assessment must evaluate how your network handles simultaneous real-time data traffic.
Checking upstream and downstream allocation
Cloud VoIP requires roughly 90 Kbps of dedicated symmetrical bandwidth per active G.711 call.
If your assessment report only shows aggregate download speeds without verifying peak upload capacity during busy hours, your data is incomplete.
Verifying Quality of Service (QoS) rules
Ask your MSP to provide proof that priority queuing (DSCP EF 46) is configured on your core router.
Without verified QoS tagging, large file uploads or video conferences will cause audio clipping and robotic voice artifacts.
ISP Modem → Core Firewall / QoS Rules → Local PoE Switch → Crystal Clear VoIP Calls
💡 Derek’s Pro Tip: Never accept a simple “Passed” status. Inspect the raw data: packet loss must stay under 1% and jitter below 30ms under peak load, or calls will drop.
Lock in your pre-migration plan
Investing in a professional pre-VoIP assessment protects your business from migration downtime.
Set clear scope boundaries, verify PoE switch capacities, and test upload bandwidth under full load to ensure a smooth transition.

Frequently Asked Questions
Why do MSPs charge separate fees for packet capture testing?
Running continuous 48-hour packet capture requires specialized deep packet inspection tools and engineering analysis time to isolate transient jitter spikes. Short speed tests typically miss this.
Can my cloud phone provider perform the network assessment instead of an MSP?
Most cloud VoIP providers offer automated web tools, but these only check basic internet speeds from a single browser. They cannot audit your local switches, firewall rules, or cabling.
What network metrics matter most in a pre-VoIP assessment?
The three critical metrics are latency (under 150ms round-trip), jitter (under 30ms), and packet loss (strictly under 1%).
