Security and Multi-Tenant Call Management

ECG designs authentication and device-management flows, ensuring only authorized calls from approved devices are recorded, with proper multi-tenant boundaries and endpoint security throughout the pipeline.
Common Challenges

Call Transcription and AI Summary Platforms Are Hard to Build and Harder to Scale

Most teams struggle with fragile pipelines, vendor incompatibilities, and the gap between raw transcripts and business-ready insights. ECG solves the problems that keep call summary tools from working in production.

icon-AIcalltranscription-3-1

Capturing Calls Across Different Platforms

Different PBXs and carriers behave differently with SIPREC, CALEA, or packet capture. Teams struggle to ensure every relevant call is captured reliably across multi-vendor environments.
icon-AIcalltranscription-3-2

Fragile Transcription Pipelines

ASR library updates, API changes, and framework releases frequently break existing call transcription flows, forcing emergency rework just to restore basic functionality.
icon-AIcalltranscription-3-3

Scaling ASR Is Expensive and Complex

Teams struggle to balance GPU/CPU usage, concurrency, and latency for real-time transcription, leading to backlogs, timeouts, or runaway infrastructure costs when call volume spikes.
icon-AIcalltranscription-3-4

Raw Transcripts Aren't Business-Ready

Getting words isn't enough – you need structured call summaries, action items, vCon objects, and redacted views that integrate with actual products like CRMs and workflow tools.
icon-AIcalltranscription-3-5

Brittle CRM and Tool Integrations

Mapping calls and AI summaries into HubSpot, Salesforce, or Monday – matching the right contact, deal, or ticket – is error-prone and often built as one-off glue code that breaks.
icon-AIcalltranscription-3-6

No Standard Format for Call Data

Without a consistent format like vCon, every integration reinvents how to bundle audio, metadata, and transcripts, making it painful to share calls across tools or evolve data models.

WHY CHOOSE ECG

Carrier-Grade Telephony Expertise Meets Modern AI

ECG brings deep, long-running experience with production telecom systems – not just greenfield AI experiments. 

We have proven ability to make SIPREC work across messy, multi-vendor environments where most teams give up. ECG brings hands-on ownership of the entire stack – from call capture through Moonshine and ASR orchestration to application-visible insights.

We partner with legal experts to deliver compliance-first, privacy-first AI call summary platforms, because "move fast and break things" doesn't work when you're breaking the law. When you work with ECG, you're working with engineers who've solved the hard problems in carrier-grade telephony and know how to make AI call transcription actually work in production.

How We Help

Best AI Call Summary Tools Built for Production Environments

ECG architects call transcription and AI summary platforms that work with your existing UC infrastructure – delivering a call summary after calls with the reliability and compliance enterprise customers require.

AIcalltranscription-9-1

Building New AI Call Summary Platforms

ECG starts with your business objectives to ensure any technology delivers true business value, not just proof-of-concept demos.

  • Integrate with your call processing stack – Microsoft Teams, Zoom Phone, Cisco UCM, Avaya, BroadWorks, NetSapiens, PortaOne, Ribbon, or others – to capture calls using SIPREC, CALEA, or packet capture
  • Focus on audio quality, reliability, and analytics to detect when call summary systems are working and when they need repair, ensuring consistent transcription accuracy
  • Consult on compliance to ensure proper call recording and transcription under two-party consent laws, GDPR, CIPA, and federal regulations – connecting you with legal authorities, not relying on ECG's legal interpretation

Troubleshooting Call Transcription and AI Summary Issues

When call transcription fails, or AI summaries don't generate, ECG investigates the deep technical reasons – from audio delivery to GPU usage to cloud configuration.

  • Analyze how ASR platforms access audio streams from SIPREC endpoints, packet captures, or recording systems to identify connectivity, format, or routing failures
  • Examine ASR transcription decoders, GPU allocation, and cloud provider configurations to ensure proper resource management and API compatibility
  • Review troubleshooting logs and analyze Word Error Rate (WER) metrics to improve transcription accuracy and identify systemic quality issues in call summary generation

Optimizing and Expanding Call Summary Capabilities

ECG assesses performance metrics on existing platforms and evaluates available interfaces to expand functionality and improve integration quality.

  • Deliver customized tools for transferring call audio, recordings, live streams, or transcriptions between platforms – enabling migration from legacy systems to modern AI call summary tools
  • Provide adapter shims connecting legacy proprietary call recording platforms with vCons and other modern standards for portable, structured call data
  • Analyze new features available on emerging AI call summary platforms to ensure optimal use of capabilities like real-time summarization, action item extraction, and CRM integration
Frequently Asked Questions

Common Questions About AI Call Summary and Transcription Solutions

Get answers to the most common questions about building production-ready call transcription pipelines, integrating AI call summary tools, and ensuring compliance in enterprise environments.

ECG uses SIPREC from platforms like Oracle, Metaswitch, BroadWorks, Ribbon, and other PBXs to send call audio and metadata into our infrastructure, handling SIPREC session setup, IP allow-lists, multi-tenant routing, and vendor quirks so that the right calls reliably arrive for processing and AI summary generation.

We can also integrate with packet capture, CALEA, or build technology directly into Session Border Controller (SBC) gateways using drachtio and RTPengine.

ASR is the engine that turns SIPREC audio streams into text, both in real time and after the call.

ECG designs the pipelines that feed audio into ASR engines, manages partial and final transcripts, handles speaker diarization, and surfaces those transcripts as structured data that downstream AI call summary tools and business applications can use to generate summaries, action items, and insights.

Moonshine is the orchestration and streaming layer that runs ASR workloads at scale. ECG deploys Moonshine to support multi-threading, manage concurrency, cope with breaking API changes, and coordinate how SIPREC-originated audio gets processed and turned into transcripts.

Moonshine works perfectly in Kubernetes (K8S) environments, allowing dynamic scaling of call transcription and AI summary workloads as call volume fluctuates.

ECG addresses real-world SIPREC issues that other providers struggle with – configuring allow-lists, handling IP-based security, dealing with vendor-specific implementations, supporting multi-tenant environments, and normalizing SIPREC behavior from different PBXs.

This ensures call recording and AI call summary generation work consistently across platforms instead of failing due to small interoperability gaps that break production systems.

ECG defines how SIPREC endpoints authenticate, how tenants are separated, and how device and account data control which calls are recorded and transcribed for AI summary generation.

We ensure call and transcript data stay correctly scoped to each customer. In many cases, this requires a strict database connecting communications platform telephone numbers with user identities to maintain security boundaries and regulatory compliance.

Yes. ECG connects call transcripts and AI-generated summaries into platforms like Wingman, HubSpot, Salesforce, Zendesk, and Monday.com. We also handle the mapping of calls to the right contacts, deals, or tickets, ensuring business call summary data flows reliably into your existing workflows.

We can also integrate with legacy call recording systems from Enghouse, CTI Group, Genesys, Dubber, ASC Technologies, Verint, CallCabinet, and NICE Systems to add modern AI call summary capabilities.

ECG's AI call summary tools generate structured outputs including conversation summaries, identified action items, extracted topics and keywords, speaker-attributed transcripts with diarization, sentiment analysis, and redacted versions for compliance.

These summaries integrate directly into CRM records as business call summary templates that sales, support, and operations teams can act on immediately – turning every call into searchable, analyzable intelligence.
