... No problem for me with this little device. The switch over of our telecom connection to IP telephony, I have taken as an opportunity to set up an in-house phone system based on a Raspberry Pi with the Asterisk PBX software. At this PBX an older, simple analog phone was connected via the Cisco Adapter now. The establishment of this is indeed gone directly to me not intuitively obvious, but was nevertheless entirely feasible in a quarter of an hour with Google Help. The external communication, ie in particular the connection to the telecom IP server assumes fully the telephone system! Over the direct connection of the Cisco with Telekom, which is in other reviews obviously did not succeed, I can therefore say nothing. The unit has been running for 6 months and is once crashed so at this time, that you had to reboot it manually (power plug). Otherwise, I have therefore in all that time have to spend another second, I'm quietly and unobtrusively his service.
