End‑to‑End Expertise
We understand the full Metaswitch Core platform – voice services, SIMPL, SIMON, and more – so you don’t have to piece together support from multiple vendors.
Streamlined Migrations
Whether you’re moving from TDM, BroadWorks, NetSapiens, or another platform, we help you plan and execute migrations without disrupting your customers.
Integrated SBC Support
We configure and integrate Perimeta and third‑party SBCs to ensure voice traffic flows securely, reliably, and in compliance with evolving regulations.
Flexible Vendor Interoperability
ECG doesn’t play favorites. We work across platforms and vendors to help you integrate Metaswitch Core with the rest of your ecosystem.
Enhanced Provisioning Workflows
From custom software to SIMPL API support, we automate provisioning tasks so your teams can work faster and more efficiently.
Built for Service Providers
We support the unique needs of CSPs and ILECs – not just the basics, but advanced features like robocall mitigation, STIR/SHAKEN, and hosted PBX delivery.
Unclear Product Roadmaps
With constant updates from Alianza and evolving Core components, it’s hard to know what’s being enhanced, deprecated, or replaced. We help you keep up.
Underused Platform Features
Hosted PBX, SIMPL, SBCs, fraud protection – if your team isn’t taking full advantage of these, you’re missing out on value you already pay for.
Complex Migrations
Moving off legacy platforms like TDM or integrating new systems like STIR/SHAKEN isn’t easy – we design migration paths that actually work.
Shortage of Skilled Staff
If your original Meta-certified engineers have left, we bring the technical depth needed to maintain and evolve your platform.
Gaps in SBC Support
Many providers struggle with SBC configuration and interoperability, especially when Perimeta is involved. We fill those gaps.

What Is Metaswitch Alianza Core?
Metaswitch Alianza Core is the rebranded heart of the original Metaswitch platform, now owned and developed by Alianza. It powers SIP trunking, VoIP call control, hosted PBX services, and key Class 5 functionality for voice providers. While often referenced as a single product, the Core encompasses a suite of components, including SIMPL, SIMON, CFS, and integration with Perimeta SBCs.
- Alianza Core combines legacy Metaswitch tech with modern cloud capabilities.
- It’s designed to support voice, messaging, and real-time applications at scale.
- Understanding your deployment’s specific components is critical for roadmap planning.
What’s the Difference Between Alianza Core, One, and Fusion?
Alianza now offers three distinct platforms: Core (formerly Metaswitch), One (a full-stack cloud solution), and Fusion (an upcoming hybrid). Each serves a different operational model and level of control. For many providers, Core is the current foundation – but knowing when and how to transition is key to long-term success.
- Core is best for providers with existing Metaswitch deployments or custom integrations.
- One offers full-stack cloud services for those seeking a managed experience.
- Fusion is expected to blend both models but may not be generally available yet.
