# History:
#
# $Log: incoming.py,v $
# Revision 1.9.2.1  2003/08/24 12:47:19  gernot
# - faxIncoming tried to reconnect when it was called after a switch from
#   voice to fax mode, which lead to a call abort. Thx to Harald Jansen &
#   Andreas Scholz for reporting!
#
# Revision 1.9  2003/06/27 07:51:09  gernot
# - replaced german umlaut in filename "nachricht-gelscht.la", can cause
