Yes we are using the Executech E80PT. In the manual it talks about the DSID feature. I thought maybe this could be integrated with DID so that callers coming in can be routed automatically to the correct intercom station.

Our new phone provider can do DID so that is what is promting these questions.

SO how does DSID work. Is it just a feature where when people call in, they get hold music and they can type in an extension. It sounds like a poor man's auto-attendant.
