I want to remotely find out if a line is working (analog in this case). When i dial it, i hear ringback and SUSIP shows CALTEREX, but i want to know if their is a wiring problem as the analog port has been reported as not working. Before going to site i would like to check that the wiring by seeing if the MD110 'sees' the extn. Is there a REN test facility? or anything else i could use?
