Cisco VP of Collaboration, Amy Chang, just gave her keynote at Enterprise Connect 2019 and we’re excited for the amazing new features and integrations Cisco has lined up for their collaboration platforms.
No matter how seasoned an engineer you are, it’s a magic feeling to reach the end of a Cisco UC upgrade. The systems are up, devices are registered, you've dodged all the bugs in the code that threatened to throw your little upgrade train off the rails of your cut plan and burning into the canyon of despair. Things are working and its time to start testing. Its at this point, that you or more specifically I in this case, noticed an interesting all circuits busy message when I attempted to dial inbound from the outside. After some quick investigation, my curiosity turned to surprise when I discovered that the customer's voicemail system had not only been compromised but, was being used to place hundreds of outbound calls to international numbers per minute. This is toll fraud. A well-known attack among voice engineers who have spent some time in the field but, largely a mystery to victims who only learn about it when they receive massive phone bills for seemingly no reason. In a nut shell, the attack leverages compromised voicemail boxes on your system to allow attackers to make unlimited international calls at your expense. While simple in theory, I thought I would try to share the details and origins of this hack below. Enjoy!
My wife and I had a baby recently which has been wonderful…save only for the lack of sleep it has brought us. Sitting up with our son and my wife at night has given me not only insight into the amazing amount of work mom’s do but, also some time to think (and catch up Golden Girls re-runs). It was still dark out, sometime early this morning, while my wife rocked our young son to sleep (again), when I started to think about my day. How could I change my routine to squeeze in 20 or 30 more min of sleep? “Maybe I could stop showering and brushing my teeth?” I thought. That would save 30 min but, probably wouldn’t fly for long with my wife.
Whether you're making the jump to cloud with Cisco Spark or sticking with your existing on premise Unified Communications implementation, the push to enable collaboration is happening in businesses across all verticals. The need to enable collaboration and empower employees to work from anywhere while maintaining the same level of collaboration as an in-person interaction is in high demand. This need is driven by the influx of millennials into the workforce, the fact that no one likes commuting, or a bit of both.
