Have some ACD groups set up in Nortel CS1000 PBX. We use "RTQT" and "RTQO" to set phones to "Not Ready" if not answered after 4 rings (RTQT). When we build CDNs to use with Symposium Express, those two options are not presented from the PBX. Is there another way to have phones put in the "Not Ready" state if not answered when using the CDN with Symposium Express?
