I followed all the steps documented in the wiki. I had it working with the old fritzbox binding. I also have the message you posted above in my log, I would expect to see a log message telling me that a connection to the call monitor port has been opened though. (TCP/1012)
I have version 6.51 installed on the 7490. I had the call monitor running since a few weeks ago while running the Fritzbox on version 6.50. If I recall correctly AVM removed telnet before 6.50. Furthermore the call monitor is not using telnet acess, but an officially supported service of the FritzBox using a specific port.
If I connect to the port by telnet I can see calls coming in:
Ralphs-MacBook-Pro-2:Downloads ralle$ telnet 192.168.x.y 1012
Connected to fritzbox
Escape character is ‘^]’.
I still think the only thing missing here to make it work as it did before is openhab connecting to the call monitor port of the fritz box.
I encountered the same problem.
In the end I decided to write a short shell script and use the exec binding.
Works for me although I would prefer to use the “official” Fritzbox-tr64 binding.
