When testing a new VRU connected to a Siemens 9006.3 with Dialogic digital JCT cards the following occurs:

If I call an extension that has voicemail from an extension that also has voicemail, I get the greeting of the calling phone. If A calls B, and they both have voicemail, if B doesn't answer I get A's mailbox greeting. Per the Dialogic documentation the channels are configured as RP400s. The extenions are configured to display the extension then name. If an extension with a mailbox is called from an extension that does not have a mailbox the calling extension is connected to the correct mailbox. I wonder what I could have set incorrectly?
