Sarond,
Not a bad solution, but I assume that you set the Ring-When to 0 so that the phones don't ring when there is a call there. Also you would probably also want to create a CRA that plays a recording that says the call has been handled or something along those lines. After that you would then set the forwarding on the phantom port to forward immediately to that CRA whenever someone tries to IC it. This stops the annoying condition when two or more people try to pick that call up at the same time. The first one gets the call, the second one intercoms it, and the third answers the second one, etc..
I must also assume that you do not do a transfer to hold, but a transfer to ring so that it lights the phantom port; correct? This would also allow the call to Recall back to the person who transferred in the first place; which in some scenarios may be what they want.
Of course in my solution I forgot to mention that the person would need to use the reverse transfer feature, default 4, and then press the Hunt Group key to retrieve the call. What I normally do is set the Hunt Groups extension to be 1 digit less than the normal extension number and then tell them to pick up 4XXX or 4XX depending on whether we are using 3 or 4 digit extensions. I also usually set the Username to be Park 4XXX so that the person knows which one is which when using a 53XX style phone.
I like your solution it is very nice and probably preferrable to some customers who want the call to return to the person who put it in park.
