The standard in secure IVR payments for mission-critical environments, with patented 3D Secure technology
Pay by Call is the specialist company that turns the telephone channel into a secure, auditable and fully integrable payment environment.
We help enterprises, public administrations, BPOs and PSPs close IVR payments with maximum security, as if they were e-commerce payments, without replacing the infrastructure they already use.
Pay by Call is a Spanish technology company exclusively focused on secure telephone payments via PCI DSS-certified IVR.
In today’s terminology, the Pay by Call platform is a PCIaaS (PCI Compliance as a Service) solution: it delivers PCI DSS compliance as a cloud, pay-per-use service.
Our proposition is built on a clear idea: we do not compete as a generic payment gateway; we solve, with deep specialization, the problem of insecure phone payments.
Since our strategic relaunch in 2020, we have built a platform designed to integrate with the PSPs, PBXs, BPOs and contact center platforms our clients already run, simply adding the missing specialist layer to secure the voice channel and reduce the high costs of PCI DSS compliance.
On top of that security layer, we add strengthened PSD2/3D Secure authentication for the voice channel—our native PBC 3DS method, with international patent pending.
Unlike generic solutions, Pay by Call treats voice as a first-class channel, not as a secondary feature.
This specialization is grounded in a telco-grade foundation that is uncommon in the payments space, in a cloud-native platform deployed on Google Cloud, and in a partner-first approach that turns PSPs, integrators and BPOs into technology and go-to-market allies.
Today we work with tier-one customers in demanding public and private environments, with live integrations in production and a clearly differentiated positioning: PCI DSS Level 1, Spanish ENS “High” category, native 3D Secure active in the voice channel, and a roadmap driven by conversational AI applied to telephone payments.
We are not just another payment gateway. We are the specialist layer that fixes the weak link in telephone payments.
