SS7 or Signaling System 7 is the dominant protocol used to control the public telephone network. Call routing, number portability, caller-ID, mobile SMS and more are handled using SS7 in the public network. SS7 (along with SIGTRAN for transport), allow application to access public network resources for call control and authentication. During this session, we share some background on SS7, show how it is used in everyday communications, and provide some use cases in popular applications.

Extending the Life of your SS7 Network with SIGTRANAlan Percy
Since the late 1970’s SS7 have been the dominant signaling standard for the global PSTN, interconnecting service providers, ILECs, CLECs, and wholesale operators. With the advent of number portability, 800-toll-free, mobile wires and SMS, SS7 had adapted and carried the bulk of the signaling to make all these services possible.
Service providers have made a significant investment in this infrastructure and have made it clear to us that they need to maximize their investment going forward.
Today we’re going to share 5 ways to leverage SIGTRAN and STPs to extend the life of SS7 network infrastructure.

Network Transformation Best Practices-Working.pptxAlan Percy
Despite the wishes of the equipment makers and regulators, there still is a lot of TDM circuits and equipment in the global telecommunications network. How do we know? We talk to service providers every day that are working in mixed TDM and IP networks. What we have found is that Service providers are often challenged with navigating the complications of migrating their network to IP infrastructure, dealing with new regulatory mandates, replacing obsolete technologies, and finding the expertise to make the transition.
To help our customers make the transition, TelcoBridges has invited ZT Technology Solutions to join us as our newest Alliance Partner, bringing a host of experience in planning service provider migrations from TDM to IP.
During this event, we discuss our Network Transformation strategy, get to meet the team from ZT Technology Solutions and hear their FIVE best network transformation practices. Best of all, we have saved some time to answer your questions.

Contact Center as a Service - Challenges and Successes Alan Percy
Contact Centers as a Service opens a range of new opportunities for service providers, offering high-margin customer care applications and improved customer experience features to small and medium businesses. Service providers building or deploying a scalable and reliable CCaaS platform will surely face challenges. We know, because we've seen the hurdles and are going to share some really innovative solutions.
In this session, we talk with Jon Arnold, the principal at J Arnold & Associates, and a leading analyst covering the contact center market.
Robocall Mitigation with YouMail and ProSBCAlan Percy
In January of 2021, over 4 billion robocalls were placed, many were part of an international scam and designed to ensnare unwitting victims. Illegal robocalling continues to be the #1 consumer complaint to the FCC. To address this, the FCC has issued numerous orders, designed to stamp out illegal robocalling and protect US consumers from fraud and other various scams. One of these orders requires development of a robocall mitigation program at the originating service provider.
In this session, we are joined by Mike Rudolph, the CTO of YouMail, to learn about their AI-powered robocall sensor network, and show how service providers and enterprises can use YouMail along with ProSBC to quickly implement a highly-effective robocall mitigation program.

Poor voice quality is one of the leading complaints for VoIP systems. Dropouts, echoes, static, and latency can ruin a conversation. Knowing how to measure voice quality and isolate the cause is an important part of delivering a quality experience to users and customers.
In this presentation, we share some background on voice quality in VoIP systems, examine the various causes of poor voice quality, and consider the role that SBCs can play in monitoring and isolating voice quality issues.
Questions covered in this session:
> Why is voice quality important to the customer experience?
> How is voice quality measured?
> What causes poor voice quality?
> How is voice quality measured on-the-fly?
> What is the role of SBCs in measuring voice quality?
> How do you isolate voice quality issues?
> Your questions
Who should attend:
Network architects at service providers and enterprises, networking consultants, analysts and decision-makers involved in acquiring network technology
Managing multiple SBCs across a complex network requires provisioning, coordination of routing-plans, performance monitoring and much more from a centralized network operations center. In this session, we take a look at using RESTful APIs as a means to manage SBCs - automating provisioning, configuration, diagnostics and other functions.
We'll also share stories from two ProSBC customers that have used RESTful APIs to manage their network configuration, making adding new subscribers easier and reducing the risk of fraud.
Building VoIP-based systems with SIP can be daunting. The entire telecommunications industry is a layered stack of technologies, some from the age of telephones with hand-cranks. Others from the Internet age of packet switching and VPNs.
Over the years, the experts at TelcoBridges have built a knowledge base about underlying telecommunications and VoIP technology, SIP signaling, networking products and design methods. In this event, we pull some of our favorite Frequently Asked Questions from our video library, our forum, Wiki, and your emails, sharing answers and insight that both beginners and advanced designers will find helpful.

New Opportunities with Two Factor Authentication (2FA) - A How ToAlan Percy
Phishing attacks are almost a daily event – the result of someone trying to trick an unsuspecting victim into sharing their username and password for their bank account or other valuable resource. Other attacks try to impersonate the victim attempting to change passwords in hopes of gaining access to their email, financial or other on-line accounts. Simple username/password combinations used to be enough to keep the bad guys out…not anymore.
Two factor authentication or (2FA) is a security tool that has become the norm to protect high-value targets, using SMS or voice calling to verify the user identity. As financial services and many other industries work to secure their systems, they need access to two factor authentication tools, including APIs, ability to send SMS and make voice calls to deliver temporary passcodes.
During this event, we’re joined by experts from both Telestax and Network Intelligence who are going to show us how 2FA can offered as a service by service providers, creating new revenue opportunities. Be sure to stay with us for information on a live demonstration you can try on your own.
Unified Communications as a Service (or UCaaS), is a relatively new opportunity for service providers, making a complete business communications solution available from virtually anywhere and billed on a monthly basis, without the cost of on-premises equipment. The OPEX model makes UCaaS extremely popular with growing and distributed companies.
One of the popular software providers enabling the UCaaS market is 3CX, an open-standards communications solution. Service providers are discovering that deploying 3CX as a service is an excellent opportunity to grow their business, bringing business-class UCaaS to a range of vertical markets and geographies. As we’ll show today, TelcoBridges’ ProSBC offers a valuable set of capabilities to make hosted 3CX implementations secure, avoids on-premises CPE, is easy to manage and the subscription-based business model makes scaling easy and affordable.
In this recorded webinar, we are joined by Matt Ussery, CIO and founder of Austen Consultants, and take a closer look at how he built his successful hosted cloud service based on 3CX and ProSBC.

Media gateways are a fundamental building block of voice communications networks, interconnecting legacy TDM voice networks and equipment with voice-over-IP networks. Found in service provider and enterprise networks, media gateways range in scale and capabilities, meeting a range of diverse applications. However, with the increasing adoption of SIP and VoIP networks, what role will media gateways play going forward? Will they become obsolete and join the VCR in the dustbin of technology? Or will they evolve to take on new roles in converged voice networks?
Welcome to “The Future of Media Gateways”, our 23rd monthly webinar, covering technical, business and partner topics to help service providers and enterprises build better voice networks.
During this session, we take a closer look at the market for media gateways, some recent innovations, and a number of new use cases. We’ll finish up with a summary of the media gateway portfolio from TelcoBridges and leave time for your questions.
The phones won’t stop ringing…or they don’t ring at all. Contact center agents waste time answering bogus calls while customers complain they can’t get through. 9-1-1 agents waste time answering robo-callers instead of dealing with real emergencies.
Telephony Denial of Service (TDOS) attacks clog up business telephone lines, causing disruption of business and wasting employee productivity. TDOS attacks can be the result of nefarious actors trying to extort money or a targeted grudge to settle, but also can be caused by rouge robocall campaigns, either way, TDOS attacks are becoming more common and difficult to prevent. Service providers are very often unprepared and unable to address TDOS attacks, leaving businesses vulnerable while they search for a solution.
Welcome to “How to Protect Against TDOS Attacks”, our 22nd monthly webinar in the FreeSBC/ProSBC series, covering technical, business and partner topics to help service providers and enterprises better secure their voice networks.
During this session, we describe methods that service providers and businesses can use to mitigate TDOS attacks, reducing or eliminating their impact. Toward the end of this session will also share three real end-customer case studies, showing how these businesses implemented their own TDOS solutions, deflecting hundreds of unwanted calls per day.
Microsoft's Azure is one of the top requested cloud platforms for communications solutions and a popular choice for hosting ProSBC and other cloud communications applications. During this session, we'll give a step-by-step tutorial and demonstration of the process to activate and configure ProSBC on Azure. At the conclusion of the tutorial, attendees will be prepared to provision ProSBC into their Azure communications solutions.
Topics covered in this session:
- Ordering process
- Selecting a processor
- Preparing the Azure account
- Preparing and Loading the ProSBC on Azure Image
- Activating the ProSBC Image
- Configuring and operating ProSBC
- Roadmap for ProSBC on Azure
- Your Questions
In this session we explore the future of new network services and how Universal CPE (uCPE) is used by service providers to combine many separate fixed-function network elements with a single multi-function device. Using virtualized network function software (VNFs) on Universal CPE, providers have a consistent and flexible foundation they can build on to offer new SD-WAN, SIP Trunking, and other services while improving network security with SBC and firewall VNFs.
How to Prevent Telecom Fraud in Real-TimeAlan Percy
Telecommunications fraud continues to plaque the industry with ever increasingly sophisticated methods and tools. From simple theft of services to international premium toll rate calling scams, stories of service providers and enterprises being stuck with thousands of dollars of fraudulent calls is a common occurrence that can be financially devastating. The Communications Fraud Control Association reports that in 2015, service providers suffered over 22 billion dollars in fraud.
During this “How To” session we will be joined by the experts from Jerasoft, showing various methods that utilize real-time billing systems and Session Border Controller software to stop fraud in its tracks!
The programmable telephone network has always intrigued me. As a developer, having the ability to create custom applications within the service provider network seems to have endless possibilities. I can envision all sorts of applications that make businesses more productive and consumers better informed. I can also envision business opportunities for service providers, offering hosted development platforms that developers can use to create new customer-facing services.
Communications Platform as a Service (CPaaS) is a means to offer an open API-based development environment to businesses of all sizes, allowing them to build custom business applications to improve their customer experience and better secure their data. Today we plan to explore opportunities for CPaaS, explain how service providers can integrate CPaaS into their existing networks and review a live customer case study of CPaaS in action.
Slides from the June 4th, 2019 webinar, introducing ProSBC.
In October 2017, TelcoBridges took the bold step to offer FreeSBC, a software-based session border controller product, to the market. Since then, over 10 million sessions of FreeSBC software have been downloaded by thousands of users around the globe. Many of those sessions are now in production or various stages of evaluation. During that time, we at TelcoBridges have been listening carefully to customer feedback and working diligently on a product development roadmap to implement those suggestions. The result is ProSBC, an enhanced session border controller offering that fits many more use cases in both service provider and enterprise applications. Today - We’re pleased to share with you an overview of ProSBC, explain its features, capabilities, target markets and use cases.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
