Abstract: A call setup process (28) in a telecommunication device (10) is controlled, wherein the telecommunication device (10) receives a user command (22) to set up a call, initiates the call setup process (28), determines that the call is likely to reach a voicemail system (14), and, in response to the determination that the call is likely to reach the voicemail system (14), automatically terminates the call setup process (28). A telecommunication device (10) comprises related features. A telecommunication network (12) is adapted to support or implement a determination whether or not an incoming call is forwarded to the voicemail system (14). The invention improves the user experience if a called party does not personally answer a telephone call.

Abstract: Disclosed herein is a process for the separate control of the methane and rare gas contents of an ammonia-hydrogen recovery-rare gas plant complex. By the controlled withdrawal of a purge gas from the synthesis gas circulation, splitting of the purge gas into two partial streams and recycling of a partial stream to the synthesis gas generation section, the increase in inert gas to be taken out of the synthesis gas circulation as a result of the modernization of the ammonia plant can be prevented negative effect on the downstream hydrogen recovery/rare; thus energetic disadvantages or costly expansions or modifications of the ammonia-hydrogen recovery-rare gas plant complex are voided.
