The held intercom call gets a line number assigned to it- I think it uses line 85 and up (or something).

ESI-Link line appearances are not supported by ESI. I think it's due to potential channel lockups, which caused them a lot of grief in earlier software versions even without line appearances. I know they wanted to, when they first brought out ESI-Link, because it was there in ESI-Access at one point though it was never in the literature.

Line supervision and packet switching are two concepts which do not "get along" well together.
