Wholesale VoIP, SIP trunking, DID numbers,
and referral income for
global business communication.
Partner with a wholesale VoIP provider built for real business use cases. VoipTower delivers managed VoIP infrastructure, international SIP trunking, premium DID numbers, and business call routing for companies operating across multiple countries. We do not just provide access — we help with setup, routing, integration, testing, onboarding, and ongoing support, so you can focus on growing your client base. You bring the client. We provide the service. You earn recurring income. Not API-only. Not a standard UCaaS platform. A managed VoIP infrastructure partner for businesses and partners that need reliable voice services, clear routing, technical execution, and long-term support.
Why partner with VoipTower
Many businesses need SIP trunking, DID numbers, international call routing, PBX integration, CRM workflows, and reliable technical support. But not every reseller, agency, telecom consultant, system integrator, or B2B service company wants to build the full voice infrastructure alone.
A managed wholesale VoIP partner behind your client projects
VoipTower works as your backend VoIP infrastructure partner. You bring qualified business demand. We help review, configure, deploy, and support the voice setup.
Recurring revenue, not one-off referrals
This gives your clients access to reliable VoIP services while helping you build recurring revenue from active client traffic — up to 10% monthly commission on active client turnover, depending on the project and agreement.
Partnership highlights
Four things that make the VoipTower partner program practical for real B2B voice infrastructure.
High-value business clients
Partners bring high-value business clients that need SIP trunking, DID numbers, international voice routing, and managed VoIP infrastructure. Call centers, B2B sales teams, e-commerce companies, logistics businesses, international service providers.
VoipTower is your backend
VoipTower acts as your backend wholesale VoIP provider. We help with routing, SIP trunking setup, DID number configuration, PBX integration, CRM workflows, testing, and technical execution.
Quality first, then price
We focus on stable business-grade voice traffic. VoipTower does not position itself as a low-quality retail routing provider. Our focus is quality first, then price.
Beyond launch
We help with onboarding, testing, launch, routing adjustments, and ongoing optimization. Your clients get a stronger technical setup, and you get a reliable infrastructure partner behind the project.
How the VoipTower Partner Program works
Four clear steps from partner request to long-term recurring revenue.
-
1. Request submission
You submit a qualified business request for VoIP services. This may include a client that needs SIP trunking, DID numbers in one or more countries, international call routing, PBX integration, CRM integration, call center VoIP setup, local business phone numbers, business telephony support, technical onboarding, or ongoing VoIP support.
-
2. Infrastructure review
VoipTower reviews the project requirements. We check country coverage, DID number availability, SIP trunking needs, expected call volume, routing requirements, PBX or CRM setup, support requirements, possible technical limitations, onboarding complexity, and long-term growth potential. This helps us understand whether the request is a good fit and what setup is needed.
-
3. Technical deployment
VoipTower helps deploy the voice infrastructure: SIP trunk setup, DID number provisioning, inbound and outbound call routing, international call routing, PBX connection, CRM workflow support, call testing, failover routing where needed, launch support, and routing optimization after launch. We handle the technical voice layer so the client can start using the service with confidence.
-
4. Long-term growth
You keep the relationship with your client. VoipTower provides the infrastructure and support behind the service. As the client grows, the setup can also grow with them through more numbers, countries, routes, integrations, and call flows. Partners can earn up to 10% monthly commission on active client turnover, depending on the project and agreement.
What VoipTower handles
Your wholesale voice infrastructure partner. VoipTower manages the technical side of international business telephony. The full voice chain: DID numbers → SIP trunking → call routing → PBX integration → CRM workflows → onboarding → support.
Request qualification
We review each project based on real infrastructure capabilities, country coverage, number availability, routing requirements, and business use case. This helps protect both the partner and the client from unclear expectations or weak technical setup.
SIP trunking setup
We help configure SIP trunking for businesses that need reliable inbound and outbound calls. SIP trunking can connect to PBX systems, call center platforms, CRM-connected phone systems, and business telephony setups.
DID number setup
We help source and configure DID numbers for business use: local presence, customer support, sales callbacks, call centers, e-commerce support, logistics dispatch, international communication, regional business phone numbers.
Call routing
We help build inbound and outbound call routing based on country, DID number, team, campaign, business hours, call quality, and failover rules. Partner clients route calls to the right destination instead of relying on a one-size-fits-all setup.
PBX & CRM integration
We help connect VoIP infrastructure with existing PBX systems, CRM platforms, dialers, and call center systems where possible. Clients use voice services inside their real business workflows.
Ongoing optimization
We support routing changes, call quality checks, number changes, configuration updates, and technical adjustments after launch. Business voice infrastructure changes over time, and VoipTower helps keep it working.

What referral partners bring
Referral partners usually bring clients that need SIP trunking, DID numbers, international call routing, business VoIP setup, call center VoIP infrastructure, PBX integration, CRM integration, local phone numbers in target countries, or managed VoIP support. You do not need to build the infrastructure yourself. You introduce the client, and VoipTower helps review the request, set up the service, and support the technical side.

Why the referral model works
Many businesses need VoIP services but do not know how to choose routes, numbers, SIP trunks, integrations, or support. If you already work with business clients, you may know companies that need better call quality, local phone numbers, SIP trunking, international call routing, call center voice infrastructure, sales team VoIP, e-commerce support numbers, or logistics dispatch routing. VoipTower provides the technical voice infrastructure. You create the introduction and earn from the client's ongoing usage.
