I have a proprietary system we use internally for speech-driven dial-by-name. it is an analog system with a pilot DN and 4 analog ONS stations in a hunt group. When you speak the name of your party, it does a hook flash and dialas this party, so it's a transfer. The issue is that when this system calls a party that is not available even though it rings the extension the call reroutes to Auto Attendant. If the called party is available, they can answer it live. Now if I dial any station in the system directly from my Multiline IP set, the call reroutes to voicemail, but I hear the individuals voicemail greeting. All of these analog stations are in the same COS as my IP sets. There are no interconnect restrictions. What am I missing and why will calls transferred by my speech system not reroute to the called aprties greeting but instead reroute to my auto attendant? Thanks in advance.
