Well, I'll go with the contrary position. I haven't yet been sold on the idea of integrating the voice and data fields into patch panels.
Now, my situation is a little different in that I'm in a campus environment, and have a centralized PBX, so in the individual buildings, I am only cross-connection from station cable to outside plant cable.
We have discussed moving the voice station cable to the rack and putting it on patch panels, for the above mentioned purpose of using "any jack for any service". Well, without moving the station cable we're doing that already, using the mentioned 110-RJ45 patch cords to go from the voice-110 field to a data switch. This is our typical situation. I don't think we've ever needed to use a data jack for a voice application. Plus, since the voice and data station is all Cat6 anyway (yes I know. Cat6 is way over kill for an analog phone) when VoIP happens, we don't have to change anything, save for pulling all the cross connect jumpers, and installing the Cat6 110-RJ45 cords.
My point boils down to, separate does not mean inflexible.
