Tnestel,
I get what you are saying about the partner mode and auto hold. I was going to think out loud here, but it may not be the best answer.
Does anyone know if he programs the system in ip full mode and unticks auto hold and changes mode if it would carry over or is it a total wash of programming?
Also, you could get creative with regular IP office mode by simply assigning line appearance buttons but would need to explain to them that they would get a double blink on incoming calls (one on the appearance key, one on the line button itself).
I am rambling, but I have to say in the end, if you can just get them to be full IPO mode and tell them the Park 1,2,and 3 are like public hold buttons that anyone can pickup just like the old line buttons, it's not that bad. I totally hear you, but we have got it down to the presentation and it's working for us selling full IPO mode.
Plus! you can add cool short codes like 101 for hunt group enable 200, 102 for hunt group enable 200 which just means that by dialing the shortcode, anyone can turn on or off their phone for incoming calls, or if they have an auto attendant, full IPO mode also gives you the ability to have a mailbox associated with a group of phones which Partner mode does not. Later on, you can offer a VPN home user, click to call email contact with tapi, remote support them and so much more.
You should buy one and just mess with it for a couple of weeks in full mode. You may be surprised how close you can come and then just polish how you present it. I learned, not to stumble in the presentation, but be more matter of fact so they don't 2nd guess you.
Lastly, as for dial 9, I prefer not to, but you could mess with that an suppress it, but it may not be 100% perfect.
I nursed the ACS for the little guys as long as I could, but I have had my fill with noisy ports, burnt tops of mods, and repaired units that still flake out on occasion. A fresh new IPO in in IPO mode is the way to go.
Hope this helps. My 2 cents.
