New platform brings eight handset manufacturers under one API and introduces invitation-based device transfers between communications providers
Liverpool, UK — 17 August 2026 — Giant Communications has launched Unified RPS, a new wholesale platform designed to simplify both zero-touch handset provisioning and the process of moving existing VoIP hardware between communications providers.
Unified RPS provides a single API and management platform across eight major SIP handset manufacturers at launch, while introducing an invitation-based transfer system that allows participating Giant partners, ITSPs and MSPs to transfer compatible RPS devices between one another.
The aim is simple: make changing VoIP provider easier without unnecessarily replacing perfectly usable hardware.
At launch, Unified RPS supports Yealink, Polycom, Fanvil, Grandstream, Snom, Gigaset, Auerswald and Panasonic provisioning services.
Making VoIP provider switching easier
Moving a business from one hosted VoIP provider to another can involve far more than porting its telephone numbers.
Even where an existing handset is technically compatible with the new provider, transferring control of its remote provisioning can be cumbersome. Devices may remain associated with the previous provider’s RPS account, require manual intervention or, in some cases, simply be replaced because doing so is easier operationally.
Giant wants Unified RPS to change that.
The platform introduces an invitation-based device transfer system, allowing participating providers to securely request and approve the movement of RPS-managed devices between organisations.
The concept takes inspiration from established switching processes elsewhere in UK telecommunications, including telephone number porting and One Touch Switch.
Instead of treating the physical handset as something that automatically needs replacing when a customer changes provider, Unified RPS is designed to make the provisioning relationship itself transferable.
A receiving provider can initiate a transfer request for compatible devices. The existing provider can review the request and approve the release, creating a clear and auditable process for moving provisioning responsibility between providers.
Once transferred, the receiving provider can redirect the existing hardware towards its own provisioning infrastructure.
For the end customer, that could mean a considerably simpler migration: keep the phones already sitting on the desks and change the service behind them.
Eight manufacturers. One provisioning layer.
Alongside provider-to-provider transfers, Unified RPS addresses another long-standing problem for VoIP operators: manufacturer fragmentation.
Each handset manufacturer traditionally operates its own redirect or zero-touch provisioning environment, with different portals, credentials, APIs and processes.
Unified RPS puts a common Giant layer in front of them.
The platform currently integrates with Yealink YMCS/RPS, Polycom ZTP, Fanvil, Grandstream GDMS, Snom Redirect, Gigaset RPS, Auerswald RPS and Panasonic Cloud.
Providers integrating with the Unified RPS API therefore don’t need to build completely separate provisioning workflows for every supported manufacturer.
Whether the device is Yealink, Fanvil, Polycom, Grandstream or another supported brand, the provider can manage it through the same underlying platform.
Built for Giant partners — and independent MSPs
Unified RPS isn’t restricted to companies purchasing their underlying voice service from Giant.
The platform has been designed for Giant partners and independent MSPs and ITSPs alike, including providers operating their own PBX infrastructure or purchasing voice services elsewhere.
This is particularly important to the device-transfer model.
By allowing different providers to participate in a common RPS ecosystem, Giant hopes to reduce one of the practical barriers businesses can encounter when moving between hosted VoIP providers.
A customer moving from one participating MSP to another could potentially transfer both their telephone numbers through the established porting process and their compatible physical handsets through Unified RPS.
Less hardware waste
Making existing handsets easier to transfer also has a secondary benefit: reducing unnecessary hardware replacement.
Business IP handsets can remain operational for many years, yet provider migrations can result in functional equipment being removed simply because reprovisioning it is operationally difficult.
Unified RPS separates the handset from the provider.
Where equipment remains technically suitable and supported by the receiving provider, Giant believes changing communications provider shouldn’t automatically mean changing phones.
That can reduce migration costs for customers, reduce deployment work for providers and extend the useful life of existing equipment.
A common device estate
Unified RPS also gives providers a single searchable view of their supported handset estate.
Features include:
- One API across eight handset manufacturers
- Invitation-based provider-to-provider device transfers
- Transfer requests and approval workflows
- Auditable transfer history
- Unified multi-vendor device management
- Multi-tenant and reseller support
- Scoped API keys
- Centralised activity and audit logging
- Webhooks for provisioning events
- Bulk device imports
- Role-based access
- Per-vendor statistics and monitoring
- Support for providers’ existing vendor credentials
Existing handset estates can also be imported, allowing providers with hundreds or thousands of deployed devices to bring them under the Unified RPS management layer.
“Changing provider shouldn’t mean changing your phones”
Callum Longworth, Director at Giant Communications, said:
“We’ve spent a lot of time looking at the friction involved in moving businesses between VoIP providers. Porting the telephone numbers is already an understood process, but the physical phones sitting on everyone’s desks can be a completely different story.
“A perfectly good handset shouldn’t become obsolete simply because a customer wants to change provider.
“With Unified RPS, we wanted to create something closer to the switching mechanisms we’re already familiar with elsewhere in telecoms. A provider can invite another provider to transfer compatible devices, the transfer can be approved and audited, and those phones can then be reprovisioned for the customer’s new service.
“At the same time, we’re solving the other major RPS problem: fragmentation. Instead of integrating separately with eight different manufacturers, providers can integrate with Giant once.
“Ultimately, we want moving a business VoIP service to become much less disruptive — port the numbers, transfer the devices and move on.”
Unified RPS launches with support for eight major VoIP handset ecosystems: Yealink, Polycom, Fanvil, Grandstream, Snom, Gigaset and Auerswald.
Behind the scenes, Unified RPS connects to each manufacturer’s respective remote provisioning infrastructure — including Yealink YMCS/RPS, Polycom ZTP, Fanvil XML-RPC Redirect, Grandstream GDMS, Snom Redirect, Gigaset RPS, Auerswald RPS and Panasonic Cloud — and brings them together behind a single Giant API and management dashboard.
This means providers no longer need to maintain separate integrations and operational workflows for each manufacturer. Devices from all eight supported vendors can be searched, managed, audited and automated from one platform.
Crucially, Unified RPS also introduces an invitation-based device transfer system between participating providers. This allows Giant partners, MSPs and other VoIP providers using the platform to transfer compatible RPS devices between one another when a customer changes provider.
The principle is similar to telephone number porting or the UK’s One Touch Switch process: rather than making the customer replace perfectly functional hardware, the existing provider can release the devices and the gaining provider can take over their provisioning.
Port the numbers. Transfer the phones. Keep the hardware.
Creating a more portable VoIP ecosystem
Giant sees Unified RPS as more than a device-management dashboard.
The longer-term objective is to establish a common provisioning layer through which communications providers can manage, automate and — where appropriate — transfer existing hardware between one another.
The company believes this could make VoIP hardware more portable between providers in much the same way that established industry processes have made telephone numbers portable between networks.
Importantly, a Unified RPS transfer does not replace the existing telephone number porting process. Instead, it addresses another part of the migration: the devices themselves.
For businesses changing provider, the combination could ultimately make a migration significantly simpler.
Port the numbers. Transfer the phones. Keep the hardware.
Available now
Unified RPS is available to Giant Wholesale partners, MSPs, ITSPs and other communications providers.
The service operates independently of Giant’s own hosted voice platform, meaning providers do not need to move their SIP traffic, telephone numbers or PBX infrastructure to Giant in order to use it.
