Common questions about ProSBC pricing
How much does ProSBC cost?
ProSBC Essentials starts at $417/mo billed annually for 500 concurrent sessions with high availability and 24×7 Level 3 support. Managed Service starts at $600/mo billed monthly, and Hosted + Managed pricing is custom based on session volume and operational scope. A Proof of Concept tier is available at $104/mo billed annually for evaluation workloads.
How does volume pricing work?
Essentials pricing is based on per-session annual rates that decrease with volume: $4.00/session/year for 500–1,999 sessions, $2.75/session/year for 2,000–4,999, and $2.50/session/year at 5,000 and above, plus $3,000/year for 24×7 Level 3 support (waived at 2,500+ sessions). For example, 500 sessions with support is $5,000/year ($417/mo billed annually). Managed and Hosted + Managed pricing scales with session volume and includes operational service.
What is included in the Managed Service tier?
Installation, security hardening, version upgrades, 24×7 monitoring, incident response, monthly operational reviews, and a dedicated Level 3 engineer. The customer hosts ProSBC on their own infrastructure and retains full control of configuration, routing rules, carrier relationships, and all CDR data.
Can I switch tiers mid-cycle?
Yes. Upgrades from Essentials to Managed Service or Hosted + Managed can happen mid-cycle with pro-rated billing. Session capacity can be expanded mid-cycle via license key, no infrastructure change required.
Are there setup fees?
Essentials has no setup fee for self-serve deployment. Managed Service and Hosted + Managed may include a one-time onboarding fee depending on complexity, disclosed in the initial quote.
What about per-minute fees?
No per-minute fees. Pricing is session-based. You bring your own carrier relationships (BYOC), so your per-minute carrier costs are negotiated directly with your carrier, not bundled through TelcoBridges.
Do you offer reseller discounts?
Yes. The TelcoBridges Partner Program offers reseller discounts for system integrators, MSPs, and consultancies deploying ProSBC for their customers. See partner details
Is the Teams Direct Routing add-on required?
Only if you need to connect Microsoft Teams Phone to a PSTN carrier through ProSBC. The add-on is $0.75/session/year and is optional.
What’s the cancellation policy?
Essentials annual subscriptions can be cancelled at the end of the billing cycle; mid-cycle cancellations are not refunded but service continues through the paid period. Managed Service and Hosted + Managed contracts with monthly billing can be cancelled at the end of any billing cycle. Individual contract terms may vary.
Can I evaluate ProSBC before buying?
Yes. The free Lab license is permanently free, capped at 3 sessions, no credit card. A 30-day free trial of the full 500-session license is also available for production evaluation. Build your lab
