| I have a DX-80 connected to a CO line that has call waiting service from the bell company. From a digital station set I can dial Feature 3 and it sends a flash hook to the CO and connects me with the new caller if they beeped in. However, when I try using the feature code from the single line set (Flash-#-3) it does not flash the otside line and all I get is a busy signal. Any ideas on why this is not working or a setting I could check? Thanks, David |
