Creating Exchange UM Greetings Using Audacity

The firm I work flow is slowly rolling out Microsoft Lync 2013 as a replacement for the myriad of phone systems we have across our offices. One of Lync’s features is the integration with Exchange Unified Messaging for voicemail.

Exchange UM allows you to create auto attendants with custom audio files. However, you’ll need to record the file yourself. I use the open source program Audacity to do so. Exchange 2010 requires .wav files encoded in Linear PCM (16-bit), in mono, with 8 KHz sampling rate.

Project Steelwall – pfSense on a Steelhead

I acquired for a reasonable price an old Riverbed Steelhead SHA-250. These are no longer supported by Riverbed, so they can be fairly inexpensive second hand.

The Steelheads all seem to be x86 based, which makes them a great appliance for pfSense. With just a little bit of work, it is easy to turn one of these appliances into a great firewall.

The SHA-250 I have has the following specs:

  • Intel Celeron-M 1.66GHz Processor
  • 1GB DDR2 RAM
  • 120GB SATA hard drive
  • 2GB flash drive, connected to an internal USB header
  • 4x Intel Gigabit Ethernet ports (*bypass pair not working in pfSense)
  • 2x External USB 2.0 ports
  • 1x DB-9 Serial Port for console

Since this will be used for my firewall at home, I removed the hard drive to conserve power and installed pfSense on the internal flash drive. Also, I can only get two of the four network ports working. The bypass pair seem to be missing some software component for them to work.

Photos can be found at the bottom of the post.
