Frequently Asked Questions

Everything you need to know about VoiceBuy wholesale VoIP termination, routing tiers, billing, and integration.

Still have questions?

Our technical team responds to integration and routing questions within one business hour.

What is VoiceBuy wholesale VoIP termination?

VoiceBuy wholesale VoIP termination is a cloud-native SIP routing service that allows carriers, MVNOs, call centers, and enterprises to send outbound voice traffic across 60+ countries using VoiceBuy’s interconnected global carrier network. Traffic is terminated via four quality tiers — Standard, Premium, Premium+, and MIX — each engineered for a different cost-to-quality balance. All routes use standard SIP (RFC3261) and bill in precise 1/1 per-second increments.

What is the difference between Standard, Premium, and Premium+ VoIP routes?

LCR

Standard — Least Cost Routing optimized purely for price. CLI delivery is best-effort and not guaranteed. Suited for bulk dialers and call shops.

CLI

Premium — Up to 50% ASR with ACD of 5–10 minutes and stable CLI across major regional networks. Suited for retail VoIP and corporate telephony.

Premium+ — Up to 65% ASR, direct Tier-1 interconnects, full CLI transparency, T.38 fax, and DTMF across 90% of global destinations. For mission-critical enterprise, banking, and MVNOs.

What is VoiceBuy MIX and how do the routing prefix codes work?

The three fixed tiers differ in routing logic, CLI guarantee, and ASR targets:

9991
→
Standard Route

9992
→
Premium Route

9993
→
Premium+ Route

This lets operators route bulk dialer traffic and live enterprise calls through a single SIP trunk without splitting infrastructure or managing multiple accounts.

How does VoiceBuy bill wholesale VoIP calls?

All standard international routes are billed in 1/1 per-second increments — you pay only for the exact airtime consumed with no rounding to the nearest minute. Three destination exceptions apply: USA is billed at 6/6, Mexico at 60/60, and Gambia at 60/1. There are no setup fees, no activation charges, and no minimum monthly volume commitments. VoiceBuy operates on a fully transparent pay-as-you-go model.

What SIP authentication methods does VoiceBuy support?

VoiceBuy supports two SIP gateway authentication models. IP-based authentication authorizes traffic from one or more static real IP addresses — no registration required, ideal for fixed softswitch infrastructure. SIP registration uses a username and password credential pair, suitable for dynamic IPs or cloud-hosted switching environments. Both methods are managed in real time through the self-service web portal at my.voicebuy.com.

What do ASR and ACD mean in VoIP termination?

ASR — Answer Success Rate

The percentage of call attempts successfully answered. A higher ASR means fewer failed connections and a more reliable route. VoiceBuy Premium targets up to 50% ASR; Premium+ targets up to 65%.

ACD — Average Call Duration

The mean length of connected calls on a route. A higher ACD indicates calls complete meaningfully without being dropped. VoiceBuy Premium and Premium+ both target an ACD of 5–10 minutes.

Is there a minimum deposit or monthly commitment?

No. VoiceBuy operates on a fully transparent pay-as-you-go model with no activation fees, no monthly minimums, and no forced volume commitments. You load credit to your account and pay only for calls made. This applies to all four routing tiers — Standard, Premium, Premium+, and MIX — and makes VoiceBuy accessible to both early-stage telecom startups and large-scale wholesale carriers.

How do I switch routes or change my plan in real time?

Route switching is instant — via the web portal or the API-driven routing controller. There are no cooling-off periods, no provisioning delays, and no support tickets required. For MIX plan users, tier selection happens at the call level using the prefix code, meaning no portal action is needed to switch between Standard, Premium, and Premium+ on a per-call basis. The entire platform is built for <strong>zero-friction, real-time control</strong>.

Can I access CDR records and invoices directly from my account?

Yes. Raw Call Detail Records (CDRs) are available on demand through the portal, archived for the last 3 months in standard CSV format for easy import into your analytics or billing systems. Monthly itemized invoices are generated automatically and available as PDF downloads — no manual billing requests required. All financial records are accessible 24/7 from your account dashboard at my.voicebuy.com.

What softswitch or PBX systems are compatible with VoiceBuy?

VoiceBuy uses native SIP (RFC3261) and integrates seamlessly with any standard Class 4 or Class 5 softswitch. Tested and compatible platforms include Asterisk, FreeSWITCH, Kamailio, OpenSIPS, Sippy, PortaSwitch, 3CX, and most major enterprise PBX systems. If your switching platform supports standard SIP trunking, it will work with VoiceBuy without custom configuration.
