I've been working with a Definity G3 through some CTI middleware for a few months now. However, I have very little knowledge over how a PBX switch actually works inside. I'd like to learn more so I can understand why certain things work and others don't.
For example, from a device in the Definity controlled through the CTI middleware, I cannot conference a VDN. Completing the conference fails until the consultation call is actually answered. However, if I conference the VDN using its external DID, the conference works immediately -- presumably because the call looks like a new, independent call once it has gone through the trunks.
Why is this? Is there a better way to do this?
