Protecting devices connected to the UC system

Devices connected to the UC system, such as SIP user terminals (VoIP phones and FXS Media Gateways) and SIP trunk media gateways, must also be secured using the best available policies.

Many currently available UC systems still do not implement proper policies or do not apply them by default. What security risks can this cause?

If TFTP is used, simply knowing the MAC address of the device allows acquisition of the provisioning file, which contains the SIP credentials to connect to any device.

How to use the bravado of the adversary to drag him by his jersey to score a goal in his own goal post

I am about to tell you a story about something that happened to me a few days ago.

Steve Osler and I had a few laughs ‘sitting at the Kite bar,’ and this is how the idea of sharing my experience with the group came to be.

In all honesty, there isn’t much to tell, but the dynamics with which it occurred is quite funny (and even educational). No soda and popcorn needed, I will be brief…

As I was saying earlier, a few days ago I went to meet with a client. A multinational player in the hotel industry, who is the owner of a structure on 7 hectares with approximately 1,000 rooms.

The purpose of my trip was just a simple visit, but I found myself casually, and indirectly, in a confrontation with the competition: Mitel. Continue reading “How to use the bravado of the adversary to drag him by his jersey to score a goal in his own goal post”

Inspecting signaling over TLS/ SSL

Any UC solution must use state-of-the-art cryptographic tools to make sure that information exchanged remains secret.

For TCP connections, the de facto standard is Transport Layer Security (TLS) and, its predecessor, Secure Sockets Layer (SSL). Both of these are frequently referred to collectively as “SSL” and are cryptographic protocols that provide communications security over a computer network.

The primary goal of the TLS protocol is to provide privacy and data integrity between two communicating computer applications. When secured by TLS, connections between an SIP, XMPP, or HTTP client (for example, a web browser) and a server (for example, wikipedia.org) have one or more of the following properties:

The 6 obstacles that block the growth of the system integrator

There is a common uneasiness among “classic” system integrators:

“We are unable to grow”

Regardless of the daily effort, abilities and experience, year after year profit is stagnant.

Sales never really take-off as you would like, and the books cry month after month.

Have you ever thought about the obstacles that prevent you from growing like other companies in your area? Continue reading “The 6 obstacles that block the growth of the system integrator”

A French Case Study: Carpe Diem Nursing Home

A contribution to the health sector and the Wildix solution become a fundamental part in a nursing home

Establishing a quality nursing home on all levels was the objective of Clotilde Hautrive, director of the CARPE DIEM nursing home, located in Compiègne.

From the construction of the building by Spie Batignoles group to the study of the information and telephone service needs, nothing was left to chance. This new medical structure, built in August of 2017, can accommodate 48 residents living with Alzheimer’s. These are patients who require a continuous and quality communication service, that is able to guarantee the wellness of the residents and that of the healthcare personnel.
