Intercom with X80s

[davidlavender]

Hello, I have not found a way yet to set up intercom an extension using a prefix button. We are coming from an ESI PBX where a simple press of the extension on an interoffice call could be set to auto answer. Anyone have any luck with this? As it is, I have to program an intercom button for every extension using *92XXX where the X is the extension. This takes up a lot of real estate.
