Welcome to ACKspace; a hackerspace located in Heerlen, The Netherlands.

A hackerspace is a place where people get together, socialize, share knowledge, tinker and build stuff.

In order to make this possible we have a collection of tools, (useful) stuff, work area and a lounge where we can relax and discuss our favorite games.

xopr 5 April 2017: I'm working on a new system to replace the current virtual machine


VoIP system with its involved servers

new system

The current system is lacking functionality and needs revisioning. Currently, the trunks that register with the extensions, don't work. When they do, participants registered to the (public) VoIP system are able to directly dial an internal space extension.

The current VoIP setup consists essentially of three servers ('nodes')

  • NLnode (primary public system, sip.ackspace.nl)
  • DEnode (fallback public system, sip1.ackspace.nl)
  • SpaceNode (internal system handling IVR and internal extensions)

The public servers are tied with SRV records as a semi-high availability setup with the primary service having high priority and weight (10 20), while the backup server has it the other way around. All (correctly implemented) services connect to the servers in the given order.

Note that currently, it is not yet possible for an extension on the primary server to call another extension on the fallback server. xopr has seen it happen that a third-party Fritz!Box falls back to the secondary server and never reconnects to the primary server without editing the credentials and reapplying the registration.

This is the SRV output:

$ dig -t srv _sip._tcp.ackspace.nl

; <<>> DiG 9.10.3-P4-Ubuntu <<>> -t srv _sip._tcp.ackspace.nl

;; MSG SIZE  rcvd: 110

All nodes connect to the BudgetPhone PSTN trunk for incoming calls, both public nodes connect to CheapConnect for the conference (and backup) number, to VoipBuster for outgoing calls and to Speakup for Limesco cell phone services. The SpaceNode connects to VoipBuster for an alternative PSTN trunk and landline services and to InterVoip for cell phone services.

When a call comes in, both public nodes try to route the call within 3 seconds: they try to call the SpaceNode user/trunk. When this fails, they try to call each other in case one of the nodes wasn't connected to BudgetPhone. If this fails, a tape will be played after 10 seconds stating that "currently, we're not reachable", whereafter the user will be placed in the (public) conference room.

If both public nodes weren't connected to BudgetPhone, the SpaceNode will answer within 10 seconds with the IVR.


current status

  • SpacePhone ENUM number
  • Dutch language for IVR
  • spacestate information logic
  • Every room has its own phone
  • possible to dial ackspace.nl sip addresses (info, conf, [username])

todo

  • Create new (vanilla) VM on new server
  • update/extend 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
  • update public SIP addressing (dedicated public IP or a VPS redirect)

wishlist

  • multilingual IVR
  • 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)

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

Chaos Communication Camp 2011

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 2011

For the open door 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 door 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.

Other events


connecting various devices to ACKspace VoIP

connecting the Fritz!Box

  • Note that the Fritz!Box is pretty quirky regarding SIP: it can't handle a 407-unauthorized correctly when in router mode (which is needed to differentiate between public and internal calls). xopr had more success setting the device as a flat switch and putting it behind a generic router (tested with a ZyXel).
  • It also doesn't like usernames; you have to start with a number and change it afterwards.
  • It does seem to have more ring power than the tested ZyXel, though.

connecting the Linksys PAP2T

The following settiings are needed:

  • TBD

Schoonmaakbord


Het schoonmaakbord was opgezet met het idee om (een deel van) de space soepel draaiende te houden.

Waarom niet meteen dat concept doortrekken naar alles wat bijdraagt aan een betere space? Boodschappen gedaan? Handig space project opgezet? Aan infra gewerkt? .. ? Vinkje erbij! Mensen verdienen erkenning voor hun bijdrages! Go team go! :P

De volgende zaken dragen bij aan een schone space en aan je collectie vinkjes (deze moet nog verder uitgeschreven worden):

  • Stofzuigen
  • Afwassen
  • Ramen schoonmaken
  • Boodschappen gedaan
  • Handig spaceproject opgezet
  • Aan infra gewerkt
  • ...
