About Mark Snow, CCIE #14073:

Mark Snow has been actively working with data and traditional telephony as a Network Consulting Engineer since 1995, and has been working with Cisco Call Manager and voice-over technology since 1998. Mark has been actively teaching and developing content for the CCIE Voice track since 2005, and the Security track since 2007. Mark's story with both data and voice technology started out quite young, as he began learning around the age of five from his father who was a patented inventor and a research scientist at AT&T Bell Laboratories. Mark started out on Unix System V and basic analog telephony, and went on from there to large data networking projects with technologies such as Banyan Vines, IPX and of course IP, and large phone systems such as Nortel 61c, Tadiran Coral, Avaya Definity and of course Cisco Unified Communications Manager in both enterprise and 911 PSAP environments across the US and internationally. Mark is also an accomplished pilot and punched his ticket in 2001. When Mark isn't learning, labing, consulting or teaching, he can be found either piloting or possibly jumping out of a perfectly good airplane, hanging off a rock somewhere or else skiing out west. He also might just be enjoying a quiet day at the beach with his wife and two wonderful young kids, Ryleigh and Judah.

    Hello Mark,

    very nice video. Dial tone was introduced in 1954, and even tough it was a long time ago, CCIE Voice candidates still look for that dial tone when they are configuring their devices in the lab ;) . Somehow not all things are meant to disappear.
    I wonder what the next evolution will be….. Hummmm we will see…..
