What is a wholesale VoIP solution?

A wholesale VoIP solution is a full carrier service package providing bulk voice termination, SIP connectivity, and supporting infrastructure — routing, billing, and NOC support — for businesses terminating high call volumes.

What uptime does the wholesale VoIP solution guarantee?

Softtop guarantees 99.99% uptime on wholesale routes, backed by direct Tier-1 interconnects, 70+ global Points of Presence, and automated failover for every traffic flow.

Does it include STIR/SHAKEN compliance?

Yes. All US-bound termination traffic is STIR/SHAKEN attested at the carrier level, ensuring your outbound calls are verified and not flagged or blocked by receiving carrier networks.

How many countries does the wholesale solution cover?

Softtop provides A-Z termination to 180+ countries, with specialized CLI and CC route options across major US, UK, European, LATAM, and APAC destinations for all traffic types.

How do I connect to the wholesale VoIP platform?

Connection is via SIP over IP. Softtop provides SIP credentials, a static IP or SRV record for trunk configuration, and technical assistance for initial route testing. Most partners are live within one business day.

What support is available for wholesale customers?

A dedicated 24/7 NOC monitors all wholesale traffic. Enterprise and carrier customers receive an assigned technical account manager and priority escalation paths for critical issues.

Carrier-Grade Voice. Scale Without Limits.

Softtop's Wholesale VoIP Solution page (at /wholesale-voip-solution) is aimed specifically at US-focused carriers, resellers, and enterprises evaluating a domestic wholesale voice provider. Six capabilities anchor the page: direct CLI and non-CLI routes across all 50 states with industry-leading ASR and ACD; bulk pricing on US domestic, toll-free, and international destinations refreshed weekly; geo-redundant softswitches in US data centers backed by a 99.99 percent uptime SLA; unlimited concurrent channels with IP authentication and G.711, G.729, and Opus codec support; live dashboards for CDRs, route performance, and minute consumption broken down by destination; and engineers available around the clock for troubleshooting, route updates, and escalations. A use-case section maps the platform to different buyer types: operators launching or scaling a voice business get white-label tools and reseller-friendly margins with no infrastructure investment required; businesses running outbound and inbound campaigns get calling at the lowest cost per minute without sacrificing quality; developers get carrier-grade voice embedded into their applications via SIP or REST API; companies replacing legacy telecom get elastic, IP-based trunking that swaps out expensive PRI lines at any scale; and US-bound traffic runs through clean, STIR/SHAKEN-compliant routes. The emphasis throughout is domestic US coverage and reliability — all 50 states, US-based data centers, and US compliance requirements — distinguishing this page from Softtop's broader international wholesale VoIP offerings. This page targets US carriers, resellers, and enterprises specifically evaluating domestic route quality, US data center redundancy, and STIR/SHAKEN compliance before committing wholesale voice volume.

Replace expensive PRI lines with elastic, IP-based trunking at any scale. Send and receive US-bound traffic through clean, STIR/SHAKEN compliant routes. Wholesale VoIP delivers voice termination, origination, and DIDs in bulk at carrier-grade pricing for resellers, call centers, and carriers, while retail VoIP serves end users on a per-line basis. Wholesale focuses on volume, route quality, and margins rather than per-seat features. How quickly can I activate Softtop's wholesale VoIP service? Most accounts are provisioned and live on the network within one business day after IP verification and route testing. Our onboarding team handles SIP configuration, codec setup, and initial traffic validation. Do you support STIR/SHAKEN call authentication for US traffic? Yes. All US-bound calls are fully STIR/SHAKEN-attested at Level A for verified traffic, protecting your call delivery rates and brand reputation from spam labeling. No. Softtop offers prepaid and postpaid wholesale VoIP accounts with no mandatory minimums, though higher monthly volumes unlock better A–Z termination rates, dedicated route engineering, and priority routing. What is the difference between CLI and non-CLI wholesale routes? CLI routes guarantee your caller ID is passed to the called party, delivering higher ASR and protecting sender reputation. Non-CLI routes are priced lower but may mask or strip caller ID, which lowers answer rates. Most operators run both on the same account, split by trunk or dial-plan.
