kClient+firmware
kServer

Current version of the kClient: X.19 (October 30, 2009)

New feature "Number of conference channel limitation" was added. It makes possible to split permanently all available PCM channels between both conferences or to reserve some channels for the conference. It may be usefull in situation where both conferences work independently and every conference must be available all the time. Default value is 0 - it means that this feature is switched of by default.
The call repetition feature is more configurable. It is possible to switch off this feature or set up number of repetition in range 1..100. Now, if the function is switched off, time controll for the connection will be done by the exchange. In prevoius versions, the KKO controlled the connection and disconnected it if supervisory time (max 60 secs) in the KKO passed by. Now, if the value is set up to 0, the controll is done by the exchange (global supervisory time).
Mechanism of attenuation regulation in conference was rebuilt and some bugs were fixed. Value -3dBm is default now (0dBm in previous versions).
Subsriber's auto answer mode is currently possible. In previous version such call sometimes was disconnected without a reason. The bug is fixed.
The KKO with Ethernet interface can't work via kServer software. This software is usefull with KKOv2 i.e. with RS232 only. Now, such situation is blocked because lack of the limitation was a reason of some troubles.

Version X.18:

New feature "CMD command files" was added. It makes possible to use leased conferences according to own demands. A customer can generate special "command" file in own application and send it into exchange folder. Such file is able to create a conference, close it, add/remove new party or annouincement etc. A password is obligatory in this conference and it is generated for given conference by an user.
New feature "Tandem 2xKKO" was added. This is fully functional service used in order to extend capacity of the conference. Now, maximum capacity for tandem 2xKKO is 118 parties. All these subscribers are maintenanced by one kClient application (like one big conference). This feature is available for KKOv3 hardware version only.
New feature : maximum call rate limitation within piece of time was added. New parameter "Call Rate in last 10 seconds" is respected. In the other case, Alarm 320 : High Call Rate was generated in multi-lim version of exchange.
PS: Special thanks to Mr Petr Radil from MUS Company in Czech Republic!
Call distribution procedure was added in the KKO 60-parties version. It makes calling phase shorter.
