Since as far back as I can remember, back to when I was Sinister 8, it's always been Bell Labs. Lucent Technologies comes in at #2. Within these two companies is the heart of telephony. From VoiceDNA, to having to say what the office number on the door is, to email verification. Web Pannels, Mail Servers, Trunk Provisioning/Siemens Overlay. Once you become one of them, the world of telephony is yours. May you arp long and poison.
