Recent Sipxcom Open Source Telephony Contributions by Peter Krautle

Thought I would provide a partial list of recent contributions to theSipxcom WIKIs that focus on integration with Internet Telephony Service Providers and voice server configurations. I am currently working on a Sangoma Session Border Controller interoperability document with Sipxcom and Microsoft Skype for Business that will be published shortly.

Some Recent Customer Feedback by Peter Krautle

Here is some recent feedback from John Karlovich of Newton Consulting - it was originally posted on my Linkedin page. All the best Peter

Peter and Louisa Voice are excellent at what they do. They have been extremely responsive and helpful regarding our phone system and firewall. Louisa Voice has helped make our VoIP server more secure and reliable. I cannot thank them enough. I would recommend them to anyone needing phone system installation or support. Peter is honest, knowledgeable, and goes the extra mile to ensure things are functioning properly.

Session Border Controller Implemented at Louisa Voice by Peter Krautle

We have just completed integrating a Sangoma Session Border Controller (SBC) into our Louisa Voice network to simplify our internal voice communications. The SBC terminates registered SIP trunks from our Internet Telephony Service Provider (ITSP) and routes incoming and outgoing calls between our internal SipXecs voice server and Microsoft Lync. We use the hotdesking, instant messaging, and video capabilities of Lync for collaboration. Main  incoming Louisa Voice numbers can be answered from either SipXecs or Lync side of the voice network, with the SBC managing the signaling, anchoring the bearer path, and performing the call routing between the two services.

Our SBC is a virtual appliance from Sangoma and was straight-forward to set up. When integration issues were encountered, the Sangoma technical support team answered questions in a timely fashion. 

The SBC will be positioned as one of our products  in some of the larger Louisa Voice customer opportunities.

The Importance of Network Monitoring in VoIP Networks by Peter Krautle

The largest telecommunications cost savings for small and medium enterprises occurs when voice and data can share the same broadband connection. In the lower NY/NJ/CT region, the competition between the carriers and cable companies for customers has resulted in good quality broadband connections to small enterprises. This means that quality voice conversations and Internet services can be delivered over the same broadband connection instead of paying for additional telephone facilities that connects your office voice system to the public phone network. 

For every customer Louisa Voice deploys, we constantly monitor the broadband connection for round-trip delay times, packet losses, and overall service availability. When issues do arise, we work with the network provider on behalf of the customer to resolve - often the monitoring history helps expedite a solution to the problem.

The router(s) used for voice and data traffic are configured at the enterprise so that voice traffic leaves the network first - this ascertains that voice quality is not compromised when the broadband network connection is congested with Internet traffic.

Finally for new installations, Louisa Voice works with the customer to assess the quality of the broadband connection and works with the provider to resolve before voice services are deployed. This significantly improves the initial voice experience for new customers and avoids the issues of troubleshooting onsite after the service is cut over.

We try hard to avoid  the 'implement and pray' approach to deploying an enterprise VoIP network - that is why we monitor the broadband connections of our customers,

Ubiquiti Router Certified by Peter Krautle

We just completed our internal certification of the Ubiquiti Edgerouter-Lite 3 router for home office and small business deployments. It's a solid edge router with great traffic shaping capabilities for voice and other traffic types at a reasonable price point. 

Much of our work centered on stress-testing the router to prioritize voice traffic over data in broadband networks where the downstream traffic is greater than the upstream. Ascertaining that firewall and traffic shaping rules are configured correctly for voice while giving equal access to other traffic types can be  expensive to resolve when voice quality issues appear in the field.

Simulating the small business network in the lab with load-generating applications and validating the traffic shaping impact on voice and data applications improves the customer experience when new systems are first deployed.

Did some last minute updates today  to the web site based on feedback I've received - am now in the process of contacting clients referenced in the Case Studies and lake photos used throughout the web site for permission to use the content.
