Is there a way to simulate line appearances on phones with a PRI, at least for incoming?

Customer replaced 12 analog lines with a PRI. They use it pretty much for incoming only. First day they are saying that calls are dropping or recalling, but I think it is because they don't see the call on thier phone when they transfer the call.

I tried my best to explain the differences. I think another point is that they transfer the calls to another switchboard through analog extensions in a hunt group. When the caller disconnects, the other switchboard does not release, so I think they use the Norstar phone to see how many callers are still connected.

I put the target line on the phone and figured out how to add multiple appearances, but when the cal is transfered, the call is removed from the phone.

Version is 7.0. Second switchboard is for a braodcast studio to take callers live on air.
