That looks like something annoying but harmless. It looks like the comms 
path is disabled slightly before the flow of packets is turned off. 
That's probably just a silly slip in the code.

Does Fritz FAX means the ISDN card stuff? If so, that should be

the FAX at the far end is buggy. I think a log of the audio from one or 
two of these calls is needed for analysis.
