Find out how many SIP trunks your business actually needs, what market-rate pricing looks like, and how much you could save vs. your current PRI or analog voice setup.
SIP trunk pricing is based on per-channel costs or unlimited monthly plans. Most providers include basic DIDs, E911, and number porting in their standard pricing.
What's typically included: Direct Inward Dialing (DIDs), Enhanced 911 (E911), CNAM delivery, local number porting
What costs extra: International calling, toll-free numbers, failover/redundant circuits, per-location E911 charges, API access
Per-Channel Pricing: $15-25/month per channel for metered service, $20-35/month for unlimited. Bundle discounts apply at higher volumes.
| Technology | Channels | Typical Cost | Hardware | Scalability |
|---|---|---|---|---|
| PRI Circuit | 23 channels | $400-800/mo | Requires gateway, line cards, maintenance | Add in 23-channel blocks |
| SIP Trunk | 1-50+ channels | $15-35/channel/mo | Existing phone system (SIP-capable) | Add 1 channel at a time |
| POTS Lines | 1 line per circuit | $35-60/line/mo | None (analog phones) | One line at a time (slow, expensive) |
Bottom line: SIP trunking costs 40-60% less than PRI for equivalent capacity, and you only pay for what you use. There's no reason to stay on PRI beyond legacy systems that can't migrate.
Per-Minute Overage on Metered Plans: Metered SIP plans often have "unlimited" minute caps, but anything over triggers overage charges ($0.01-0.03/min). Read the fine print.
Failover Circuit Requirements: Many providers require a secondary circuit or failover option for business-class SIP. Budget $50-200/mo for redundancy.
Contract Length: Most SIP providers want 1-3 year contracts. Early termination fees can be significant. Negotiate exit clauses.
Porting Fees: Moving existing numbers to a SIP provider typically costs $1-5 per number. Budget $50-500 depending on volume.
E911 Per-Location Charges: If you have multiple office locations, E911 service might charge per location. Can add $5-15/location/mo.
API & Automation: Advanced features like call recording, call routing, and IVR APIs often cost extra or require an add-on package.
