Had this puppy up and running for over three years and ready to cut the cord from the old definity switch. PSTN -> Definity -><- VoIP. This build is a Xeon(R) CPU X5550 @ 2.67GHz dell server which is over kill, better safe than sorry. Have three years of CDRs and two years of 215779 recordings in/out I covert to mp3 bit rate of 16k on off peak times every day and only using 11% out of 536.98GB HD. Receiving faxes inbound and outbound and emailing them. Have FOP2 working great. I just finished the queue/ivr menus for the call center (I'll let you know when I active that). Had it up for over 48 weeks with out a glitch (THANKS ELASTIX TEAM)Now just want to cut over to the PSTN "isdn-pri network".
