[Freeswitch-users] Better approach for multi-tenant SIP testing (part 1)

Cal,

I took a different approach and took advantage of a rack of Polycom
phones and a bit of electronic tinkering.

I took the Polycom 550s and, using the built-in XML Command Push and the
state polling features, plus some perl automation, I was able to
automate a large batch of call scenarios. Then when I found that SLA and
BLF lights weren't available, I assimilated the phones borg style.

In the album, I'm using an Arduino board, a muxer(to talk to multiple
chips easily), and a set of light sensors(color, and intensity) to now
detect presence issues in FreeSWITCH.
