synopsis

Create and/or implement a telephone communication system for companies to communicate with the front desk or vice versa, for notifications, emergency and-or quick automation.

This idea was mentioned before: not only can we be informed there is a pizza delivery boy at the desk, but also other companies can benefit from a telephone/intercom system.

The cheapest setup would be SIP/RTP (VoIP); make use of the current network infrastructure. I happen to have a system with FreeSWITCH running, but it's currently in experimental mode.

Be aware that FS has a very steep learning curve, but once you get the point, you'll never want to go back (hint: regular expressions ftw)

implementation

Current setup consists of the following:

  1. a public accessible number
  2. simple IVR menu
  3. permanent space phone (1001)
  4. simple conference room (3100)
  5. various participant registrations (see #extensions)

extensions

This is the list of registered extensions. If you want to register your own extension, let Xopr know. For available extensions, refer to the #dialplan

Also note that 085 can have a special tariff

todo

  • Correct dialplan (faster dialing)
  • Open up 19xx registrations
  • Trunking over VPN
  • install PoE blade
  • add other extensions (other residents)

history

CCC

The CCC Binary Voice Radio telephony server was a mixed success. Actually, it was a disaster: -The visual ring indicator circuit didn't trigger the optocouplers so that was the first thing to fail. -a lot of power failures which caused a lot of downtime and eventually database corruption -the DECT system was getting too complex for the simple phones we've modded for field reporting (Technical clarification came from one of the Eventphone key people who explained that the antenna register on cheap phones was too small to identify them all). Besides that, it looked like the cabling had short-circuited because the 9v battery didn't have any oomph left to generate amplified audio. -wifi had a hard time maintaining the links and coverage wasn't 100% so the wifi field reporter wasn't a good alternative -last but not least: the public ip addressing threw a spanner in the works and the server went limbo. The server's database went corrupt, and after a restore, it didn't match the regular config files. I got it semi-working after it was far too late to make it useful to the studio. Also, after I got it to work, it wouldn't register correctly to the Eventphone trunk and we only got to call the editorial room (2781|BVR1) via DECT twice or so. Despite all that stress, it was promising, so better luck next time.


Open door day

For the open day, I set up a stand-alone test system with two Cisco 7940s, a FxS/FxO and dual FxS ATA, which included some softclients.

The phones were successful in a rough field test on the open day, connected to a FreeSWITCH exchange and two ATAs which provided connections to two additional analog handsets. The field test proved reliable enough and a great platform for some hilarious phone pranks.

The Cisco phones had a menu where you could view a 2 bit grayscale snapshot of the two space cams, and you were able to switch some outlets. People were allowed to navigate the configs and exploit functionality and LuckY sniffed and replayed audio over a wifi link.

future

  • Move the current setup to the SAN server and release the current setup as a ACKspace FS playground.
  • Create a larger deployment of the VOIP network as a testing ground for a more high-traffic environment.
  • Stoney would like to build a visual ring indicator which flashes once somebody calls a specific number.

notes

Here's some information on how to power the Cisco 7940's through standard PoE switches. As featured on CampZone 2011. Thanks, Stoney
