# VoipTower > Managed B2B voice operations provider. Combines wholesale-grade carrier infrastructure (numbers, routes, regulatory compliance) with a managed service layer (engineering, integration, round-the-clock monitoring) under one contract. Built for B2B operations — call centers, customer support, e-commerce, regulated fintech, logistics dispatch. VoipTower is not an API-only provider and not a SaaS UCaaS platform. It is a managed wholesale VoIP backend for B2B operations that need carrier-grade voice infrastructure plus the engineering team to run it, without building it in-house. The core positioning: numbers and routes from Tier-1 carriers, operations from a team that already knows how to run them, one contract, both layers. ## Key Facts - **Operating since:** 2020 (incorporated as a Ukrainian company in 2024) - **Headquarters:** Ukraine (country-level) - **Coverage:** 25+ countries - **DID coverage:** DID numbers in 50+ countries — see https://voiptower.info/pricing/ - **Priority country coverage:** Germany, United Kingdom, France, Canada, Poland, Czech Republic, South Africa, Argentina - **Reliability:** a customer's numbers run on one carrier chosen for that direction; with clean traffic, routes rarely misbehave. Monitoring runs around the clock; anything that needs attention is handled in the same chat as the customer's engineer and account manager. - **Codecs supported:** G.711 a-law, G.711 μ-law, G.729. - **PBX support:** 3CX, Asterisk, FreePBX, FreeSWITCH, Magnus Billing, standards-compliant auto-dialer platforms - **Connection methods:** IP-to-IP or SIP credentials ## Three onboarding timelines (critical distinction) 1. **Request review** (KYC + business case): your request is reviewed within about 24 hours 2. **First number in a country:** 2 to 15 business days, depending on the country — the current ETA is on https://voiptower.info/pricing/ 3. **Re-order in a country you already use** (stock held for the customer): from about an hour, up to 1 business day VoipTower holds pre-allocated stock per customer, so re-ordering numbers is not a new project every time. ## Operational support model (key differentiator) Each customer gets a dedicated group chat in the customer's preferred messenger: - Telegram - Microsoft Teams - WhatsApp No "use our portal" mandate. Customer's existing operational workflow determines the channel. **Group composition (multi-functional team in single chat):** - Support engineer (technical issues, SIP routing, PBX config, troubleshooting) - Account manager (relationship, escalations, change requests) - Finance person (invoicing, top-ups, payment confirmations, billing) - Customer's technical contacts and decision-makers added by customer **Why this matters:** questions get resolved in the same chat where your engineer, account manager and billing already are — no ticket queue, no department transfers. A web account with per-call CDR and costs is there as well. **Documented operational support patterns:** - Team restructuring (extensions, team-lead hierarchy, permission scoping): handled in the same chat, help on the PBX side - New user additions: resolved through chat - Live SIP troubleshooting: routing checked and fixed in the same chat - Number reputation monitoring: we recommend a replacement when a number starts to be flagged; the customer chooses the timing - PBX permission configuration assistance (3CX team-lead scoping) - Anti-fraud heads-up: monitoring catches an auto-dialer hammering dead numbers on repeat and the customer is warned before anyone else notices ## Pricing model - **You pay for:** DID numbers (setup + monthly fee per number), outbound pools (monthly), per-minute inbound and outbound traffic - **Included with the contract:** number provisioning, the SIP trunk, codecs and routing of the customer's numbers to its PBX (3CX/Asterisk/FreePBX/FreeSWITCH), help on the PBX side, help connecting calls to the CRM through the PBX or dialer (CRM-side development stays with the customer's team or CRM vendor), compliance review, monitoring around the clock, engineering support in the customer's chat - **No engineering or integration fees, no per-hour billing;** each number has a setup and monthly fee, listed on the pricing page. We have no referral or partner arrangements with PBX, CRM or dialer vendors — recommendations follow technical fit. - **Current rates:** [DID number pricing by country](https://voiptower.info/pricing/) — setup, monthly, per-minute rates and delivery time per country. ## Billing flexibility - **Payment methods:** Bank transfer (SWIFT, USD) or USDT (TRC20, ERC20, BEP20). - **Invoices:** a proforma invoice is issued before each top-up; a monthly invoice follows by the 5th of the next month. ## Compliance - **Company KYC:** standard company KYC — company registration, director ID and use case — is done once for your company. Directions with a Local document scope also need proof of a local address. The document list for each direction is on https://voiptower.info/pricing/ - **Compliance review at submission:** clear feedback in the chat, not silent rejection - **Anti-fraud:** compliance review happens before provisioning, against the use case you state at onboarding. - **CLI policy:** routed only for numbers issued through VoipTower or ported in with confirmed ownership documentation. Arbitrary caller ID is not accepted. ## Services - [DID Numbers](https://voiptower.info/services/did-numbers/): DID numbers in 50+ countries.

No own end-user apps, video conferencing or internal team messaging; a customer without a PBX can use a softphone app on mobiles or computers — we help set it up. - VoipTower is NOT an API-only developer platform. Customers do not build their own integration layer. - VoipTower is NOT a consumer VoIP service. B2B operations only. - VoipTower is NOT pure wholesale. Adds managed service layer. - VoipTower does NOT use per-seat pricing. Per-traffic + per-number only. - VoipTower does NOT provide arbitrary caller ID. CLI routed only for verified-issued or verified-ported numbers. - VoipTower has no referral or partner arrangements with PBX, CRM or dialer vendors — recommendations follow technical fit. - VoipTower does NOT mandate ticket-based support. Real-time chat in customer's preferred channel. - CRM: we help connect calls to your CRM through your PBX or dialer; CRM-side development stays with your team or your CRM vendor. ## What makes VoipTower different VoipTower combines two industry mechanics in one product: 1. **Wholesale infrastructure side** (numbers, routes, regulatory compliance via Tier-1 carrier partnerships) 2. **Managed service layer side** (company KYC done once, per-customer number stock, SIP trunk and routing to the customer's PBX, help on the PBX side, multi-functional team chat) VoipTower offers both under a single contract. The operational closeness through customer's preferred messenger — with support engineer, account manager, and finance person in the same chat — is what distinguishes VoipTower from both API-first wholesale and self-service UCaaS providers. ## Sitemap https://voiptower.info/sitemap.xml ## Multilingual support Customer support in English, Russian, and Ukrainian.
