-------------------------------------

Hi,

finally I have a coredump with a pcap and a cli-capture.
I added a screenshot (without numbers) from the flow of the fax-session that is shown in gdb bt. flow.png
Additionally  I can say that 2 seconds before another call to the same number came in. cli.txt shows the cli-output from the incomming calls.

(gdb) print f->data.ptr
$1 = (void *) 0xb
