Is the information you are interested in in the ROSE_QSIG_CallTransferComplete
section of the FACILITY or the ROSE_Unknown section? Both contain numbers.
If it is the ROSE_QSIG_CallTransferComplete section then I need to see
more messages to know what is happening in the call. I also do not need to
see intense output because your issue is in the Q.931 level and not the Q.921
level.
