has anyone ever used an 827-4v DSL router to do SIPtoPOTS conversion? how would I set up my 4 pots lines to be SIP extensions/phones? any ideas? Cisco site is a little lacking on sample configs. I would like to set up 3 of the ports for FXS analog sets and one port for FXO. convert all the analog to SIP and send it to a SIp gateway like FWD or Asterisk. Any thought or suggestions/examples would be a great help Thanks Dave
