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 26-11-2011|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 [[User:LuckY|LuckY]] sniffed and replayed audio over a wifi link. === Other events === * Moving to the [[Putgraaf]]: Used a (wrong) [https://en.wikipedia.org/wiki/Yagi%E2%80%93Uda_antenna Yagi antenna], connected to HeerlenLive, [[VPN|tunneling]] to the server in the [[xCBS]] building, making it ACKspace's first offsite VoIP phone in a place where there wasn't even carpet or ventilation * [[Open_Door_Day_30-3-2013|Open door day 2013]]: Experimented with a cluster of [[Raspberry Pi]]s and put some phones on various locations on the ground floor * [http://illegaleshow.nl/ illegale show 2013(?)]: Provided power, [[Guerilla_VoIP|uplink and DECT]] in a location about 80m away from any utility facilities * [[Open_Door_Day_28-3-2015|Open door day 2015]]: probably one of the largest setups counting physical phones; no features whatsoever * [[Open_Door_Day_26-3-2016|Open door day 2016]]: lot's of lag on the skinny protocol (controlled by a Raspberry Pi == connecting various devices to ACKspace VoIP == {{:Fritz!Box|transcludesection=connecting_Fritz!Box}} {{:Telephone_system:Analog_Telephone_Adapter|transcludesection=connecting_PAP2T}} {{:Siemens_Gigaset|transcludesection=connecting_N510_IP_PRO}} {{:Telephone_system:Analog_Telephone_Adapter|transcludesection=connecting_SPA3000}} {{:Thomson_ST2030|transcludesection=connecting_ST2030}} [[Category:Telephony]]
