if a number is dialed that legitimately fails it keeps trying all the other endpoints / pbxs /faxs

[AVNECLD]

solicited below are two devices one is an ip office one is a fax server.  if a call goes out on the ip office (172.16.99.41) and it is to a legitimately failed number the SBC keeps trying until it dials the fax server (in this case voice grouped-trunk 172.17.99.11) instead of passing along a busy signal etc.
