    How To Not Get Fired By Not Buying Cisco How To Not Get Fired By Not Buying Cisco Presentation Transcript

    • How To Not Get Fired By Not Buying Cisco
        • How we saved $1m on a VOIP PBX and lived to tell the tale
        • Anthony Rodgers
        • Shayne Dunlop (aka Rick Pratt)‏
        • District of North Vancouver
    • A Little History
      • Had an aging Nortel Meridian Option 11C
        • High maintenance costs
        • Reaching end-of-life
      • Tried VOIP as early as 1999
        • Nortel
        • Televantage
      • Plagued with echo and interoperability problems
    • A Little History
      • Abandonment of Televantage led to search for alternatives
      • Discovered Asterisk Open-Source Software PBX on the Internet
      • Pilot install in Spring 2005
      • Production install in Fall 2005
      • Now over 400 phones at 15 sites
    • Infrastructure Ditech E/C Asterisk Test Asterisk 1 Asterisk 2 Allstream Telus 23B+D 3B+D 23B+D Polycom IP501 Sipura ATA 911 IAX Trunk
    • Challenges
      • Interoperability with Nortel
        • Support from user community, online documentation
        • Had to work around caller ID issues
      • EeCcHhOo.......
        • Long loop to GTD5 CO
        • Tried software EC, on-board EC
        • Bought a Ditech carrier-grade EC appliance
          • Thanks, Vic!
    • Challenges
      • Handset selection
        • Single largest expense
        • Evaluated Snom, Aastra, Polycom, Grandstream
        • Polycom emerged the winner
        • Mostly IP501 sets, a couple of IP601s
        • Very pleased so far
      • Wifi handsets
        • Use UTCStarcom, but no clear winner
    • Handset Criteria
        • PoE
          • Maintain phone service during a power outage
        • Built-in switch
          • Most workstations only have one drop
        • Software-defined labeling
          • No whiteout-encrusted labels
        • Remote administration and provisioning
        • SIP standard
        • User acceptance
    • Challenges
      • Failover
        • Two identical production servers
          • Second is a hot standby
          • Use VSS to mirror configuration between them
            • Also has advantages for migrating from test to production
        • Voicemail stored on separate server
        • Polycom phones use DNS SRV records to automatically switch to hot standby server
        • PRIs are switched using the Armstrong method
    • Challenges
      • 911
        • Took the view that we are the telco for our staff, and have responsibility to provide accurate 911 location
        • Municipal Hall is covered by PRIs
          • All other locations have at least one 1B line
          • Billing address is set to street address
        • Dialplan matches calling phone to location and places call on appropriate 1B line using ATA
        • ATAs have power and Ethernet failure detection
    • Challenges
      • Unified Messaging with MS Exchange 2007
        • Got it working via SIP Express Router (SER) ‏
          • Jammed the pump with a small stone
          • Got the fish tank dirty
          • Waited to be put in plastic bags
          • Rolled across the counter, out the window, through the grass, across the road, over the edge of the dock and into the bay
        • Now what?
    • What Is It?
      • Full-featured, open-source, software PBX
        • Standard PBX features
          • Voicemail, auto-attendant, staff directory, music on hold, etc.
        • ACD Queues
        • No-cost conference bridging
        • Telecommuting – local extension at home
        • Anything you can program it to
    • How To Do It
      • What we did
        • Requires in-house skills, adoption of open-source mindset
        • Probably the hardest way to not get fired
      • Consultants

    • How To Do It
      • Tailor-made Linux distributions
        • One install does it all

          • FreePBX

          • Fonality (Trixbox) ‏
