Thanks for all the suggestions so far. Specwar, your suggestion is basically what we are doing now. All the other company phones are 7941's so they just have to do a PickUp dn# if the call is not transferred from the 7961. I'll read through the example configs to see if I can learn anything new. I'll post a solution if I find a better way.

I recently setup a customer similar to this, who wanted all the PBX features, but still wanted it to work like a key system. needless to say, it was a pain of an installation.

What I did was create a DN for each PSTN line they had, then setup each line appearance on the phones with a normal ring button. The trick is to then have the users put the call on hold (not transfer). So the receptionist would recieve a call on line 1, put it on hold, and ask the destination staff member to 'pick up line 1'. that way the call is always active on that DN, and the line status is monitored.

Does not make for the best configuration, but they were happy.

Configuring the system in KTS mode should help you accomplish what you need.
