Be aware that <abbr title="FreeSWITCH">FS</abbr> has a very steep learning curve, but once you get the point, you'll never want to go back (hint: regular expressions ftw)

My ([[User:Xopr|Xopr]]) personal interest is pulling the all types of communication into a central point and thereby link them.

=== current status ===
 +
Every room has a phone now, albeit analog, DECT or ISDN, see todo for Cisco 7900 setup.

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.

Cisco IP Phone 7940 series

synopsis

Create and/or implement a telephone communication system for fun and automation. It can provide conference rooms, reach key people from a central number, quickly notify if the space is closed and provide a quick and cheap way of communication.

xopr 12:43, 28 September 2015 (CEST): I'm working on a new system to replace the Guerilla VoIP which starts to fail more often. It doesn't have a public IP address (yet), so participants SIP addresses are yet to be implemented

new system

The current (emergency) system is starting to fail and needs revisioning, and it's time for a more permanent solution anyway.

current status

Every room has a phone now, albeit analog, DECT or ISDN, see todo for Cisco 7900 setup. The phones connected to the Fritz!Box are connected to both VoIP systems which in their case, are both connected to the VPS.

todo

  • add outgoing trunks (dialplan)
  • fix SpacePhone ENUM number
  • add Dutch language for IVR
  • add spacestate information logic
  • fix IVR menu
    • mention the space state before actually answering (183:progress)
    • start with a brief menu, but give more info on demand
  • add support for Cisco 7900 phones (Cisco phone deployment)
    • need to put an interface on a different VLAN
    • update all switches to offer the same VLAN
    • add TFTP and add the firmware + configs
    • update the DHCP (option 66 or 150)
    • update dialstring to both signal SCCP and SIP

wishlist

  • multilingual IVR
  • conference rooms
  • enable fax/modem detect
  • enable 2600 toying option
  • key people (1333)
  • Add a HAM autopatch system to the telephony system so sip phones and amateur radio are interconnected
  • simple intercom service
  • number lookup script
  • various participant registrations (see #extensions)
  • some scripting to ease life and add some nifty features
  • trunking over VPN
  • install PoE blade or smaller PoE switch (might want to choose for regular power supplies)

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

Note that numbers for remote and external network services behave differently:

  • Local services are called on the server itself (where the user is calling to)
  • Remote services are either upstream (parent) if it is a private server (typically behind NAT),
    or a fallback (sibling) server in case of a public server
  • External might be of several things:
    • alternative upstream (fallback server)
    • alternative sibling (fallback or 2nd fallback server)
    • 3rd party service

One can make the assumption that remote services within the space are forwarded to it's local service upstream (public VPS) with a few minor exceptions: Motivationals and Radio can be serviced anywhere; see it as Bergeijk being external and Poetry comes via (emulated) Citizens band radio and thus is remote


Interactive Voice Response

The concept for the new IVR menu will have something like this:

ack_main and ack_info (are the same, but with different spoken texts)

  • 1[059]\d: direct dial extensions
  • 2 switch to English language
  • 3 switch to Dutch language
  • 5 direct dial ring group
  • 6 dial key persons, enable voicemail detect and use time schedule
  • 7 go to conference rooms
  • 8 go to menu ack_extra
  • 9 go to menu ack_info
  • 0 go to menu ack_directory

ack_extra

  • 1 more info on space state (time of toggle)
  • 2 speak out telephone number and/or IP address
  • 3 listening rooms
  • 4 extended time service
  • 5 contact location abroad (when online)
  • 6 echo test
  • 8 call test setup
  • 9 repeat this menu
  • 0 go back
  • * go to main menu

ack_directory

  • 100 for slACKspace (lounge)
  • 101 for hACKspace (workshop)
  • 109 for DECT (wireless)
  •  ??? for chairman
  •  ??? for secretary
  •  ??? for treasurer
  • 1(all other public extensions)
  • 5 call anyone
  • 8 lookup by typing first three characters using keypad
  • 9 repeat this menu
  • 0 go back
  • * go to main menu


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.
