The specs for this network are:

  • My home telephone number is 6105555555 (pretty cool, eh?  j/k – that is a fictitious number for this posting.)
  • Cisco PoE Capable Switch
  • Cisco 2811 Series Routers w/256 memory and 512 compact flash
  • VIC2-2FXO card for analog telephone in the house
  • VIC2-2FXS card for the connection to the Telephone Company
  • Cisco ASA 5500 Firewall for Internet connectivity
  • Cisco 7960G IP Phones
  • Cisco 7920 Wireless Phone
  • A few normal Analog phones around the house.
  • Hold music via multicast – BMG.wav
  • Web services hosted on berbee.com
  • CallManager Express v7.1

So, quick background on the FXO and FXS cards. These cards are what allow you to connect your router to the Telephone company for inbound/outbound calling or to an analog phone.  The FXS provides battery to (S)tuff, FXO points toward the Central (O)ffice (Thanks Tom for the analogy)
Below is an image that depicts the cards and their connections.
