Technically there should have been a site survey done before the access points were installed, and that would have provided you (or should have if the person doing it was worth their salt), the TX the access points should be operating within.
That being said, what power levels do those phones operate at? Assuming they are lets say 14dBm, then you would want your access points to be running around the same power level to ensure no near/far issues occur.
Phones can be very particular with how you deploy wireless, so if your doing a voice over wireless solution, the wireless design is usually catered to those phones first and foremost.
You'll want to ensure you have fast-roaming (or as close to it as you can get) enabled. How are the phones authenticating? What channels do the phones support, and what channels are you using on the access points?
What power level are the access points settling onto (assuming your using the autoRF feature)?

I'm not familiar with that product.
What do you mean they only play nice on 2.4? If they support 5GHz I would only use that if I were you.
Do they have communication issues even when you don't move, or is it only during roaming from one AP to another?

This seems to be the configuration manual for that phone:

Check to see how you have the phone configured. Is it scanning every channel available (wasting time) or is it only scanning the channels your using? If your using 2.4GHz (which I don't recommend) then only scan 1/6/11. If your using 5GHz only SSID (it's recommended to have a dedicated SSID for the phones, make it 5GHz only, try to avoid using DFS channels).
Make sure your switch ports for the access points are all configured correctly as well, in case there is a vlan issue somewhere.
